Is sneezing in cats contagious to humans?

The common causes of sneezing in cats, including cat flu, are not contagious to humans. There is usually nothing to worry about if a cat sneezes on you. There are some cat illnesses that cause sneezing and can be caught by humans, but these are very rare. If a cat does sneeze on you, particularly an unknown cat, it’s best to wash the area with soap and water. Speak to your doctor if you do start to feel unwell. 

Could my cat have COVID-19 if they are sneezing?

There is some evidence that cats can catch COVID-19 from an infected human, but it’s extremely rare. If they do catch the virus, sneezing can be a symptom. But cats usually have no symptoms or very mild symptoms and recover quickly. The chances of cats spreading COVID-19 are very low. Humans are much more likely to catch it from other humans. If you have COVID-19, you can reduce the risk of giving it to your cat by limiting contact with them as much as possible while you’re sick. If you think your cat might have COVID-19, discuss this with your vet. 

What is reverse sneezing?

Reverse sneezing is when a dog rapidly sucks in air though their nose causing a loud snorting noise. It helps them to clear their nostrils of any irritants and is usually completely harmless. Reverse sneezing is not something that cats typically do. Cats are more likely to do a normal sneeze if they have irritants in their nose.
