Information about COVID-19, Pets, and Other Animals

A number of animals worldwide have been infected with the virus that causes COVID-19, including pets like cats and dogs, farmed mink, and large cats, gorillas, and otters in zoos, sanctuaries, and aquariums. Reptiles and birds have not been affected by this virus. The risk of animals spreading the virus to people is low, but people with COVID-19 can spread the virus to animals during close contact. The information linked to below provides guidance for pet owners, public health professionals, animal health and wildlife officials, veterinarians, and others on how to prevent the spread of COVID-19 between people and animals.

Maybe It’s Time to Take Animal Feelings Seriously

Dogs can read human emotions. So, it appears, can horses. Whales have regional accents. Ravens have demonstrated that they might be able to guess at the thoughts of other ravens — something scientists call “theory of mind,” which has long been considered a uniquely human ability. All of these findings have been published within the past several weeks, and taken together they suggest that many of the traits and abilities we believe are “uniquely human” are, in fact, not so unique to us.

Maternal Gorilla Received Box Of Kittens For Her Birthday

Koko was one special gorilla. She could communicate very well with her handlers and loved taking on a mother role to other animals. After becoming a part of the longest experiment to teach language to another species, Koko had become an icon for The Gorilla Foundation. Aside from art, Koko also loved kittens.

According to The Gorilla Foundation, Koko loved babies. Although her handlers weren't able to find Koka a baby gorilla, they did find her the next best thing. As a gift for her birthday, her handlers got Koko a box full of adorable kittens.

Nabisco Animal Crackers Boxes Got A Makeover And Now The Animals Are Roaming Free

Nabisco's parent company redesigned Barnum's Animal Crackers boxes to show the animals roaming free — and not in cages — after pressure from PETA.

These cookie critters are tasting freedom.

After spending 116 years behind bars, the majestic beasts on boxes of Nabisco Barnum’s Animals Crackers are no longer being depicted in lock-up.

Nabisco’s parent company, Mondelez International, redesigned the snack's packaging in response to pressure by People for the Ethical Treatment of Animals.

PETA, which has denounced using animals in circuses, wrote a letter to Mondelez in the spring of 2016 calling for a redesign, according to AP.

“Given the egregious cruelty inherent in circuses that use animals and the public’s swelling opposition to the exploitation of animals used for entertainment,” PETA wrote to the food giant, “we urge Nabisco to update its packaging in order to show animals who are free to roam in their natural habitats.”

Mondelez agreed and started working on a makeover.

Rebooted cookie boxes, which declare “new look, same great taste,” are on U.S. store shelves now.

The new boxes have the same lettering and color scheme, but a zebra, elephant, lion, giraffe and gorilla wander side-by-side outside, instead of being confined in circus boxcars.

A Few Years Before Koko Passed Away, She Shared an Important Message to Humankind that Needs to Be Heard Now More Than Ever

The world was struck with grief once again when the beloved gorilla, Koko, passed away at the age of 46.

Koko's ability to use sign language to communicate with people warmed the hearts of millions worldwide.

She even became best friends with Robin Williams, and felt tremendous grief after learning about his tragic death in 2014.

It wasn't just Koko's ability to learn American Sign Language that stunned the world, it was her empathetic personality and worldview that everyone found to be so fascinating.

As Koko got better at communicating, thanks to the efforts of animal psychologist Francine "Penny" Patterson, many people wondered, "What could ape say to mankind?"

The former San Francisco Zoo resident actually had a lot of important things to say.

Gorillas may not be smarter than humans, but we sure could learn a lot from them.

A few years before Koko passed away, she shared an important message to humankind that needs to be heard now more than ever.

For the 2015 United Nations Climate Change Conference, Koko had an important message for world leaders.

"I am gorilla. I am flowers, animals. I am nature," she began signing in front of a dark background.

"Man Koko love. Earth Koko love," she continued. "But man stupid, stupid! Koko sorry. Koko cry. Time hurry."

Then she looked down in deep thought, before finishing off her message. "Fix Earth. Help Earth. Hurry! Protect Earth. Nature see you. Thank you."

As much as many people would like to deny the existence of climate change, it's only doing a disservice to the world by thinking that the burning of fossil fuels and the destruction of the environment is not making a negative impact on the world.

As Koko said, she's part of nature, and so are we.

It's humankind that has a powerful impact on this world, and it's up to us to change the world for the better.

Koko, The Famous Gorilla Who Learned Sign Language, to Be Laid to Rest at Animal Sanctuary

Koko, the gorilla who mastered sign language and became a pop-culture phenomenon, will be laid to rest Saturday in a ceremony at an animal sanctuary in Northern California where she lived for decades.

The western lowland gorilla died in her sleep Tuesday morning at the age of 46, according to the Gorilla Foundation, which is headed by animal psychologist Francine "Penny" Patterson, who worked with and cared for Koko since the primate was a year old.

Koko was renowned as one of the most intellectual apes in history, beloved by millions of people around the world. Under Patterson's tutelage, she learned more than 1,000 words in sign language and came to understand over 2,000 words spoken to her in English.

"She taught me more than I taught her, for sure," Patterson, 71, told ABC News in a telephone interview Thursday. "She had opportunities to show her brilliance and that’s what we saw. We saw a person, really. She had all the attributes of a person and then some."

A Germophobe Gorilla? Philadelphia Zoo Primate Walks Upright So He Won't Get His Hands Dirty

An 18-year-old gorilla named Louis hates to get his hands dirty. That’s why he sometimes walks upright like a human -- especially when food is involved.

Louis, a 500-pound, 6-foot tall gorilla that lives at the Philadelphia Zoo, walks upright when he’s carrying tomatoes and other snacks, The Associated Press reported.

He also walks upright when the ground is muddy, according to the Philadelphia Zoo, which recently posted a video of Louis walking on two legs.

Weekend Outing at Cincinnati's Zoo Turned Tragic When a 4-Year-Old Boy Was Hospitalized After Falling into a Gorilla Enclosure

A holiday weekend outing at Cincinnati's zoo turned doubly tragic Saturday when a 4-year-old boy was hospitalized after falling into a gorilla enclosure - and zoo workers had to kill the rare gorilla to protect the boy.

Cincinnati police and emergency crews responded to a report of a child falling into the exhibit at the Cincinnati Zoo & Botanical Garden at about 4 p.m. Saturday. Police confirmed the child was taken to Cincinnati Children's Hospital Medical Center near the zoo, and was treated for serious injuries that were not considered to be life-threatening.

Cincinnati Zoo President Thane Maynard said the boy crawled through a barrier and fell an estimated 10 to 12 feet into the moat surrounding the habitat. He said the boy was not seriously injured by the fall.

The Cincinnati Fire Department reported in a press release that first responders "witnessed a gorilla who was violently dragging and throwing the child."

Maynard said the zoo's 17-year-old male western lowland gorilla, Harambe, grabbed the boy and dragged him around. Two female gorillas were also in the enclosure.

The boy was with the 400-pound animal for about 10 minutes before the zoo's Dangerous Animal Response Team deemed the situation "life-threatening," Maynard said.

"The choice was made to put down, or shoot, Harambe, so he's gone," Maynard said. "We've never had a situation like this at the Cincinnati Zoo where a dangerous animal needed to be dispatched in an emergency situation."

The fire department release said  the boy was in between the gorilla's legs at the time of the shot.

Maynard said the Dangerous Animal Response Team followed procedures, which they practice in drills. He said in the 38-year history of the zoo's gorilla exhibit that they've never had anyone get into the enclosure.

After the gorilla was shot, zoo employees unlocked the gate and two firefighters quickly retrieved the child, according to the fire department.

"It's a sad day all the way around," Maynard said. "They made a tough choice. They made the right choice because they saved that little boy's life. It could have been very bad."

Brittany Nicely of Dayton was visiting the zoo with her two children and four other children on Saturday. They were at Gorilla World when the incident took place.

"Out of the corner of my eye, I saw the little boy in the bushes past the little fence area. I tried to grab for him. I started yelling at him to come back," Nicely said.

"Everybody started screaming and going crazy," she said. "It happened so fast."

Nicely said the gorilla rushed toward the boy and led him by the arm through the water in the enclosure. She said initially the gorilla seemed protective and only alarmed by all the screaming.

The area was then evacuated by zoo staff. Nicely stood with her group outside the exhibit.

"About four or five minutes later we heard the gunshot," she said. "We were pretty distraught. All the kids were crying."

Nicely said she spent the whole trip home explaining why they are told to stay close and not run at the zoo.

"That could have been them," she said. "Something like that could have happened. It's a very traumatizing experience for anybody involved. The kids, the zookeepers, the other gorillas that now don't have him there any more."

News of the incident triggered huge social media response.   A video posted by the Enquirer  had been viewed about 71,000 times at 9:30 p.m. Saturday.

Many commenters criticized the parents of the boy for not watching him more closely. A Facebook group called Justice for Harambe was created and gathered more than 100 "likes" in less than two hours.

"This page was created to raise awareness of Harambe's murder on 5/28/16," the page states. "We wish to see charges brought against those responsible!"

Lt. Steve Saunders, the spokesman for the Cincinnati Police Department, said no charges were being pursued against the child's parents.

The decision to shoot Harambe instead of tranquilizing was made in the interest of the boy's safety, Maynard said.

"In an agitated situation, it may take quite a while for the tranquilizer to take effect," he explained, "At the instant he would be hit, he would have a dramatic response. You don't hit him and he falls over."

Maynard also explained that while Harambe didn't attack the child, the animal's size and strength posed a great danger.

"All sort of things could have happened in a situation like that. He certainly was at risk," Maynard said. "Our thoughts and prayers are with the family and little boy.”

He said that zoo officials have not yet spoken with the family of the child who fell into the habitat. Zoo officials will be reviewing the security of the enclosure and their procedures, but said they have no plans to stop the gorilla program.

Harambe was born at the Gladys Porter Zoo in Brownsville, Texas before he was moved to Cincinnati in September 2014. Another gorilla, Gladys, named for her home zoo, also come to Cincinnati from Brownville.

Western lowland gorillas are one of the four gorilla subspecies. According to the World Wildlife Foundation, populations of the critically endangered animal are hard to estimate due to the dense, remote rainforests where they make their home, but experts say between 175,000 to 225,000 could live in mostly in Congo, but also in Angola, Cameroon, Central African Republic, Equatorial Guinea, and Gabon.

In 2009, the International Species Information System counted 158 male western lowland gorillas and 183 females in captivity in the United States.

"Harambe was good guy. He was a youngest who started to grow up. There were hopes to breed him," Maynard said. "It will be a loss to the gene pool of lowland gorillas."

The zoo is open Sunday, but Gorilla World will remain closed until further notice.

Researchers Witnessed a Couple of Four-Year-Old Gorillas Working Together Dismantling Poachers’ Traps

Not long after a poacher’s trap killed a young mountain gorilla in Rwanda’s Volcanoes National Park, researchers actually witnessed a couple of four-year-old gorillas working together to take apart other traps in the area. Large gorillas are able to use their strength to do this, but the younger ones aren’t.

“This is absolutely the first time that we’ve seen juveniles doing that . . . I don’t know of any other reports in the world of juveniles destroying snares. We are the largest database and observer of wild gorillas . . . so I would be very surprised if somebody else has seen that.” – Veronica Vecellio from the Dian Fossey Gorilla Fund’s Karisoke Research Centre in Rwanda

It’s sad to think that thousands of snares are set up in these areas, leaving many animals to be caught and left to die.

As Science Alert Points Out:

While adult gorillas are large and strong enough to extract themselves, young gorillas often are not, and if they don’t die from being stuck in the trap, they run a very real risk of dying from injuries sustained during their escape, such as dislocated bones and gangrenous cuts.

Here is the brief version of how the events unfolded from National Geographic:

On Tuesday tracker John Ndayambaje spotted a trap very close to the Kuryama gorilla clan. He moved in to deactivate the snare, but a silverback named Vubu grunted, cautioning Ndayambaje to stay away, Vecellio said.

Suddenly two juveniles—Rwema, a male; and Dukore, a female; both about four years old—ran toward the trap.

As Ndayambaje and a few tourists watched, Rwema jumped on the bent tree branch and broke it, while Dukore freed the noose.

The pair then spied another snare nearby—one the tracker himself had missed—and raced for it. Joined by a third gorilla, a teenager named Tetero, Rwema and Dukore destroyed that trap as well.

Humans have strayed far from the teachings of our ancestors. We once knew the importance of preserving and respecting all living things on this planet. Now, with the rise of today’s consumerist culture, we focus instead on acquiring material possessions, only to discard them and acquire even more, newer versions of these possessions. Worse still, much of what we purchase today has its roots in child labor and animal cruelty/suffering, and all of this is done for the sake of economic growth and globalization.

As a result, as studies have recently shown, the Earth has entered into a mass extinction phase. Vertebrates are disappearing at a rate 114 times faster than normal. These include mammals, birds, reptiles, amphibians, and fish, and there are several reasons for this decline. For example, an acre of land is cleared every second to graze animals and grow their food crops, resulting in the loss of over one hundred plant, animal, and insect species. Climate change, pollution, and deforestation seem to be the main culprits.

At the rate we are going, it seems unlikely that humans will be able to survive on this planet as close as one hundred years from now.

This entire experience, however, has served us in a way like no other. More and more people are starting to become aware of what is really happening on this planet and are starting to feel the urge to change. This is a good sign, and something that’s desperately needed at this time. I personally feel that our planet is actually shifting itself in the right direction, but it seems likely that it will be a challenging, if worthwhile, process for us all.

Meet Shabani, The Handsome Gorilla That Has Japanese Girls Going Ape Over Him

Shabani, the 'handsome gorilla' is driving Japanese girls mad. The Australian-raised gorilla finds fame as women flock to the zoo to see him because he is 'so good-looking'.

Shabani now lives in Higashiyama Zoo and Botanical Gardens in Nagoya, and has attracted a large following of admirers who visit him because he is so 'handsome'.

The western lowland gorilla was raised at Sydney's Taronga Zoo but moved to Japan in 2007.

Zoo officials said there has been a notable increase in young female visitors thanks to Shabani.

His rise to fame has been fueled largely by Twitter, where fans post pictures of him claiming he is 'too handsome'.

His adoring Twitter following often refers to him as an 'ikemen', which means a 'good-looking man'.

Taronga Zoo’s Senior Zookeeper, Allan Schmidt said “Shabani was moved to Australia from The Netherlands as a two-month-old in December 1996 with his family.”

When asked if he was surprised by Shabani's popularity he said, “No because the Japanese are crazy... The Japanese love their fads.”

He added, “I would say most people would consider him fairly dashing.”

Schmidt said this is not the first time 18-year-old Shabani has enjoyed viral internet fame.

After moving to Nagoya, he was pictured in 2007 walking along a tightrope in the zoo enclosure.

“He's used to the limelight. He was born in The Netherlands and moved to Australia as a baby, where he grew up with a very stable father and mother”, he said.

“It's not surprising he's very successful, he was moved to Japan to mate with three female gorillas, where he has had two healthy male offspring.

Shabani has lived at the Japanese zoo since 2007, but has only recently become so popular, Rocket News 24 reported.

Pictures of the gorilla posted online capture him in moments where he appears to be flexing his muscles, staring broodingly into the distance or playing with the younger gorillas.

Comments posted online describe him as 'hot' and 'too handsome'.

“I went to Higashiyama Zoo. This hot Shabani ikemen was certainly handsome,” one woman wrote.

Another posted photos with the caption: “Shabani who is in Higashiyama Zoo is famous as the too handsome gorilla!”

Meanwhile another visitor posted a picture at the zoo with friends with the caption: Went to see the handsome gorilla Shabani... it was a fun holiday.”

The Question of Whether Only Human Beings Deserve Human Rights: Chimpanzees Get a Day in Court

A year after the starting fight for legal personhood for the research chimpanzees Hercules and Leo, the apes and their lawyers got their day in court. At a hearing in Manhattan on Wednesday, a judge heard arguments in the landmark lawsuit against Stony Brook University, with a decision expected later this summer. At stake: the question of whether only human beings deserve human rights.

A decision could set a precedent for challenging, under human law, the captivity of other chimpanzees—and perhaps other species. It’s a radical notion, and many legal experts doubted whether the lawsuit, one of several filed late in 2013 by the Nonhuman Rights Project, would ever reach court.

But Justice Barbara Jaffe decided to consider the arguments. “The law evolves according to new discoveries and social mores,” she said while presiding over the hearing. “Isn’t it incumbent on judiciaries to at least consider whether a class of beings may be granted a right?”

Jaffe posed that question to New York assistant attorney general Christopher Coulston, who represented the university, where the two chimps are housed. Coulston had argued that Jaffe was bound by the previous decisions of two appellate courts, which had ruled that other Nonhuman Rights Project chimps didn’t qualify for habeas corpus, the legal principle that protects people from illegal imprisonment.

Both those decisions are controversial. In one, judges decided that habeas corpus didn’t apply because the chimp would be transferred from one form of captivity to another—in this case, a sanctuary. But illegally-held human prisoners have been released to mental hospitals, and juveniles into the care of guardians.

In the other appeals court decision, judges declared that chimps are not legal persons because they can’t fulfill duties to human society. But that rationale arguably denies personhood to young children and mentally incapacitated individuals, as several high-profile legal scholars, including Constitutional law expert Laurence Tribe, pointed out. He filed a brief on behalf of the Nonhuman Rights Project, saying the court “reached its conclusion on the basis of a fundamentally flawed definition of legal personhood.”

In fact, Nonhuman Rights Project attorney Steven Wise argued, New York law only requires judges to follow appeals court decisions involving settled legal principles—which animal personhood is not. That set the stage for the pivotal question: What is the basis of legal personhood? Wise said it’s rooted in the tremendous value placed by American society and New York law on liberty, which is synonymous with autonomy. “The purpose of the writ of habeas corpus isn’t to protect a human being,” he said. “It’s to protect autonomy.”

By that standard, Wise said, chimpanzees qualify. “Chimps are autonomous and self-determined beings. They are not governed by instinct,” he said. “They are self-conscious. They have language, they have mathematics, they have material and social culture. They are the kinds of beings who can remember the past and plan for the future.” In a human, argued Wise, those capacities are grounds for the right to be free.

Coulston marshalled an argument elsewhere made by Richard Posner, a legal theorist and federal appeals court judge who has written that legal rights and personhood were designed with only humans in mind. “Those rights evolved in relation to human interests,” Coulston said. “I worry about the diminishment of those rights in some way if we expand them beyond human beings.”

The cognitive capacities of chimpanzees have been compared to 5-year-old humans, said Coulston; how would the legal system handle animals with minds comparable to a 3-year-old, or a 1-year-old? “This becomes a question of where we’re going,” he said, with chimp personhood opening the floodgates to lawsuits on behalf of animals in zoos or on farms, or even pets. “The great writ is for human beings,” he said, “and I think it should stay there.”

Wise countered by saying that denying freedom to an autonomous being is itself a diminishment; it could even come back to bite us, serving as rationale for limiting human freedom. He described the slippery slope as a separate issue. Freedom—or at least sanctuary—for Hercules and Leo is something to debate on its own merits, just as rights for any potentially deserving human should be considered without regard for social inconvenience.

It is true, though, that success could lead to personhood claims on behalf of other chimps, as well as other great apes, orcas and also elephants, for whom the Nonhuman Rights Project is now preparing a case. More than a third of Americans now support rights for animals.

Win or lose, Wise said at a press conference following the trial, the hearing itself was a victory. “Many human beings have these kinds of hearings,” he said. Chimpanzees “are now being treated like all the other autonomous beings of this world.” Whether they’ll continue to get that treatment will be up to Justice Jaffe. Or, more likely, whoever hears the almost inevitable appeal of her decision.

A Western Lowland Baby Gorilla Was Born At The Lincoln Park Zoo, in Chicago, Illinois

There's a new reason for families to swing over to Lincoln Park Zoo. A western lowland gorilla was born there in this week. Visitors can get their first glimpse starting Saturday.

The zoo is cautiously optimistic about the baby's health.

"The infant is looking very strong; it's clinging tightly to mom, and we're seeing a really good pattern of nursing for several minutes from both breasts then taking a nap afterward," said Maureen Leahy, curator of primates.

Mom Bahati, age 27, shows solid maternal instincts, Leahy said.

"At this stage, although the infant can cling on and sort of support herself, she can't do it for very long," Leahy said. "Mom will hold her close and tight to her chest even when she's out and about or climbing. We look for her to support the baby's head, very much like humans."

The newborn joins a troop of six individuals, including 2-year-old half-sisters Nayembi and Patty, born at the zoo in fall 2012. At one point, Patty approaches the newborn slowly, then reaches to brush her fingers over her nose as mom munches hay.

That's where silverback dad Kwan, 25, comes in.

"He is doing a really good job keeping a watchful eye over the new mom and infant," Leahy said. "The two toddlers are very curious; they've been approaching a lot and touching the infant, but when they start getting too bold, Kwan will come over and sit down next to Bahati and kind of cue the toddlers to take a step back and give the new mom a break."

Bahati had not given birth since 2004. Her two adult offspring now reside in other Association of Zoos and Aquariums accredited zoos.

Gorilla Scares Children at Zoo With Routine

A gorilla at the Henry Doorly Zoo in Omaha, Nebraska, likes to give his onlookers a thrill. As seen on this video, he waits motionless then lurches toward the viewing enclosure and gives it a bang. Shrieks -- and cheers -- ensue.

According to the person who filmed this, it’s a part of his regular routine. “The cool part is that he waits for someone to enter the barrier and a crowd before doing this routine,” he told Storyful.

Among the Millions Mourning the Death of Robin Williams on Monday was Koko, a Gorilla who Communicates in Sign Language

Among the millions mourning the death of Robin Williams on Monday was Koko, a gorilla who communicates in sign language. Williams met Koko in 2001 at The Gorilla Foundation in Northern California, where the great ape managed to upstage the great comedic actor.

“Years later (on Aug. 11, 2014), Koko overheard Penny (Dr. Penny Patterson, Koko’s mentor and surrogate mother) talking on the phone about Robin, who had just passed away,” The Gorilla Foundation stated on its website. “She became extremely sad.”

“When you remember Robin Williams, remember that he is not only one of the world’s most beloved entertainers, he is also one of the world’s most powerful ambassadors for great ape conservation,” the organization said.

For his part, Williams called his conversations with Koko a “mind-altering experience.”

The encounter with Koko was just one of many efforts Williams made over the years on behalf of wildlife. In 2011, the actor appeared with other celebrities in a TakePart video to call attention to the annual slaughter of dolphins at the cove in Taiji, Japan, where the few survivors are sold to zoos and water parks.

“My friend doesn’t belong in captivity,” Williams says in the video. “The others are brutally killed.”

In 1995, the comedian narrated and starred in the PBS documentary In the Wild—Dolphins With Robin Williams. He followed the work of marine biologists and swam with Atlantic spotted dolphins in the Caribbean.

In the Wake of Robin Williams' Death, Will We Finally Start Taking Depression Seriously?

As with Koko, he attempted to communicate with his newfound dolphin friends.

“What’s up, my main mammal?” he asked a spotted dolphin.

Closer to his Marin County, Calif., home, Williams once made an impromptu appearance at a fund-raiser for the local humane society, jumping onstage to riff with another comedian.

“The Marin Humane Society is very sad to hear about the passing of Robin Williams,” the group said on its Facebook page on Monday. “In 2009, we were honored when he gave a surprise performance at our Woofstock benefit concert.”
