Overview: Can cats catch and spread SARS‑CoV‑2?
Yes, cats can become infected with SARS‑CoV‑2, the virus that causes COVID‑19, but serious illness is uncommon. Most cats have mild or no symptoms, and severe disease is rare. Current evidence indicates that cats are not a major driver of community spread, and the risk of animals transmitting the virus to humans remains low. Key practices—such as isolating a sick cat, avoiding close contact if you are unwell, and maintaining hygiene—can further reduce any potential risk. This page explains what the science shows and what to do if you think your cat may have been exposed.
How cats can be infected
Routes of transmission
Cats most often catch SARS‑CoV‑2 from infected humans, whether through respiratory droplets or contact with contaminated surfaces. There is limited evidence that the virus might spread between cats in households or shared environments, but cat-to-human transmission is considered very rare. Other species, such as dogs, ferrets, and some zoo animals, have also been infected, but cats appear to be more susceptible than dogs. The virus uses the ACE2 receptor to enter cells, and cats have receptors that can bind the virus, which supports documented infections.
Household and shelter settings
In households where a person has COVID-19, cats may be exposed through close, prolonged contact. In group settings like shelters, outbreaks have been reported, often linked to high-density housing and shared equipment. Simple measures—such as isolating an infected person from pets, having a healthy person care for animals, and practicing hand hygiene—can lower the chance that cats are exposed.
Symptoms and detection in cats
What illness looks like
When cats do develop signs, they are usually mild and may include fever, coughing, sneezing, runny nose, eye discharge, lethargy, reduced appetite, vomiting, or diarrhea. Some cats show no obvious signs yet can still test positive for the virus. Because these signs overlap with many common cat illnesses, testing and veterinary assessment are important if you suspect COVID-19.
Testing and diagnosis
Veterinarians typically collect samples from the nose, mouth, or stool to detect viral RNA. A positive PCR test may indicate an active infection or, in some cases, recent exposure where the virus is no longer replicating. Your veterinarian will consider your cat’s clinical signs, contact history (such as exposure to a person with COVID-19), and local transmission levels when interpreting results and recommending care.
What to do if your cat may have COVID-19
Immediate steps and care
- Contact your veterinarian before visiting the clinic to discuss symptoms and possible testing.
- Isolate your cat from other pets and people, especially those who are at higher risk.
- Have a single, healthy household member care for the cat to reduce household transmission.
- Use separate food and water bowls, litter box, and bedding, and clean them regularly.
- Wear a mask and gloves when handling the cat or its items if you are symptomatic or immunocompromised, and wash hands thoroughly afterward.
When to seek veterinary care
Seek urgent veterinary attention if your cat has difficulty breathing, persistent coughing, severe lethargy, loss of appetite for more than a day, or signs of pain. Even with mild symptoms, call your clinic ahead so staff can prepare to protect other animals and people in the practice.
Prevention and practical measures
Reduce risk in multi-person households
If someone in your home has COVID-19 or is waiting for test results, minimize close contact with pets. Ideally, another healthy household member should feed, clean, and interact with the cat. Avoid sharing food, kissing, or letting the cat sleep in your face. Keep the cat indoors if possible to limit exposure to unknown animals outside the home.
Hygiene and facility management
Regular handwashing with soap and water before and after handling pets, bowls, or litter helps reduce the chance of spreading viral particles. Clean and disinfect shared surfaces frequently, and ensure good ventilation in living areas. In group housing such as catteries or shelters, reduce density, increase space between animals, and implement routine health checks to catch infections early.
Long-term considerations and outlook
Available data indicate that most cats recover fully from mild COVID-19 infections with supportive care. Reinfection appears possible, especially as the virus evolves, but reports remain limited. Public health agencies continue to monitor situations where people and animals share spaces to refine guidance. Ongoing communication with your veterinarian about local case trends and risk factors helps ensure that care decisions are up to date.

Comparing cats, dogs, and other animals
Among common pets, cats appear more susceptible to SARS‑CoV‑2 than dogs, and both can carry the virus after contact with infected humans. Ferrets also show high susceptibility, while birds and reptiles generally do not support efficient replication. The differences reflect variations in ACE2 receptors and viral binding efficiency. Regardless of species, the main source of infection for pets is people. Managing contact, hygiene, and density helps protect all animals in multi‑species households.
When to contact professionals
If you suspect your cat has been exposed to COVID-19 or is showing respiratory or gastrointestinal signs, reach out to your veterinarian before visiting the clinic. Public health departments and veterinary schools can provide advice on local case trends, testing options, and safe handling practices. Reporting unusual clusters of illness in shelter cats can support broader surveillance and inform guidance for other facilities.
Bottom line
Cats can become infected with COVID-19, usually after exposure to an infected person, and they commonly experience mild or no symptoms. The risk of cats spreading the virus to people is very low. Most cats recover with supportive care, and simple precautions—such as isolating sick individuals from pets, practicing hand hygiene, and minimizing close contact—can further reduce risk. If your cat shows signs or has known exposure, contact your veterinarian for tailored advice and testing.
