Pets and COVID-19: Infected By Humans

Two cats in New York state, and later a pug in North Carolina, were diagnosed with COVID-19, the disease caused by the coronavirus SARS-CoV-2, in the past few weeks. What does that mean for those of us who live with cats and dogs?

Really, just that we should be careful not to spread the disease to our pets, as apparently happened here, but there is no evidence that pets have spread the disease to people.

The two cats, from different households in different areas in New York state, developed mild upper respiratory symptoms. One of the cats lived with a person who was known to be infected by COVID-19, so no surprise there. The second cat did not live with a known infected person, however, and while it’s apparently an indoor-outdoor cat the speculation was that it was infected by a “mildly ill or asymptomatic household member” or another person outside the house. Their veterinarians had PCR (polymerase chain reaction) tests for SARS-CoV-2 done at a private veterinary laboratory and both cats tested presumptive positive. The laboratory then reported the results to state and federal officials, required for certain animal diseases in the U.S. in order to comply with national and international reporting procedures.

The United States Department of Agriculture’s (USDA) National Veterinary Services Laboratories (NVSL) collected additional samples and confirmed the discovery of antibodies to SARS-CoV-2 and announced its findings. NVSL serves as an international reference laboratory and provides expertise and guidance on diagnostic techniques, as well as confirmatory testing for foreign and emerging animal diseases. Both cats are expected to fully recover.

And the pug?

The pug in North Carolina lived with infected humans and also tested positive as part of a study with Duke University, though another dog, a cat, and a lizard tested negative. Brachycephalic breeds like pugs are subject to respiratory conditions so it’s not clear, even with the positive diagnosis, that the respiratory condition was due to the COVID-positive diagnosis because dogs don’t seem to be as susceptible to the virus as cats, for instance.

Again, all notices tell us there is nothing to be concerned about as far as being infected by our pets, though the do need to be concerned about us.

Update on big cats in the Bronx Zoo

A Malayan tiger named Nadia was tested and found to be infected with the coronavirus at the Bronx Zoo after exhibiting symptoms, and six other big cats were exhibiting symptoms as well. No one is certain how the cats were infected. The zoo staff presumes it was from an asymptomatic or presymptomatic staff member though no one has been tested, but no one has developed clinical symptoms of COVID-19. The zoo closed on March 16, even to volunteers. Staff members don’t physically interact with the big cats which is puzzling because infection seems to take a prolonged exposure to the disease. The cats developed the characteristic dry cough and diminished appetite. Only one tiger was tested because general anesthetic was required for a blood draw.

Later several more big cats at the zoo were tested by fecal sample, which does not require anesthesia to collect. Several other cats tested positive, but one positive cat was asymptomatic. In all, eight cats were infected, but many other big cats were not. In this case, the initial testing was done at Cornell University, and, as with the little cats described above, the confirmatory testing was done at NSVL. All the infected cats are recovering well.

Coronaviruses and zoonoses

Early on, the coronavirus that came to be called COVID-19 was speculated to be zoonotic, meaning it originated in an animal but could then infect humans. Could it also be spread from humans to animals by reverse zoonosis? And then back to humans?

Right now, all situations indicate that we can indeed, on rare occasions transfer COVID to our cats and even dogs, but there is no instance yet of any of our domestic pets transferring it back to us.

In a video interview with the Association for Animal Welfare Advancement, Dr. Sandra Newbury, Director of the Shelter Medicine Program at the University of Wisconsin noted, “In New York City right now there are numerous people who are sick with COVID, we can assume that many people have cats, and we are not seeing cats flocking to the emergency room in crisis from COVID infections.”

Dr. Newbury continued, “There is no sign at all that animals are part of the serology of this disease. When we study the disease travel from one place to another we can always trace that to a human.”

But she cautioned that there is danger to our cats from us. “We do know that there is the possibility that humans can infect our beautiful cats” though haven’t seen that happen in the US yet, but she noted we haven’t tested much. “Let’s be so careful,” she said, “because we don’t want people to panic.”

Most importantly, Dr. Newbury suggested, people need to have a care plan for their pets in they instance they themselves develop COVID-19 and they should quarantine away from their pets as well as humans, finding someone else to feed and care for them.

Social distancing for your pets!

However, we still need to keep our pets in our social distancing plan—meaning that we need for them to quarantine as we do and keep a distance from other people and animals when we leave our quarantine area.

  • Dogs at the dog park should keep a distance from other dogs—and from people, just as we should.
  • Indoor-outdoor cats should not roam and mingle with other cats, animals and people.
  • Continue feeding your community cats because caring for animals is considered “essential” under all definitions, employing all social distancing and wellness guidelines. If you become ill, stop, quarantine, and find another caretaker to take your place.

Fur can act as a fomite, a material that can catch and hold the infection just like any doorknob or keypad. If an infected person coughs on your cat and your cat comes home and you pet and hug your cat, the infection could be transferred to you.

And in reverse, anyone who is infected with COVID-19 should quarantine themselves from animals just as they distance themselves from people to keep from spreading the virus to either animals or people. If you become sick with COVID-19, no matter how sick you are, someone else should care for your pets.

Several very new and very small studies of SARS-CoV-2 infection in animals have shown that the disease is more infectious among ferrets and cats who will develop symptoms and develop antibodies and other ferrets and cats near the infected animals will also catch the infection within days. Another study of cats only from Wuahan China showed that cats will become seropositive when in homes with actively infected humans, and will also develop infection from a milder exposure. Exposed dogs will typically not develop symptoms but may develop antibodies showing they were infected and their immune systems responded. Pigs and chickens showed no changes.

While it’s good to know they won’t suffer from the disease as much as we do, animals who develop the disease, even if they are asymptomatic or only develop antibodies may lead to an animal reservoir for this disease that keeps it in the environment.

Caring for your community cats in the COVID-19 era

Alley Cat Allies assures it’s fine to provide food and water for your community cats, but refrain from contact for both their good and your own. Wash your hands before you dish out the food and water to be sure you don’t transfer anything to them. Wear gloves when you clean up their feeding area, disposing of the dishes if disposable, and thoroughly washing their food bowls if not.

There are no prohibitions on caring for your community cats. Just remember that the bigger risk is from us to them.
