Yeah, I posted too hastily - the Snopes piece was actually about a case in Europe someplace (Berlin?) where a covid patient's cat got sick, and was diagnosed with coronavirus, although it wasn't clear if it was
the coronavirus, and if it was, how much there was, i.e. was the cat actually sick because of it, or had it just picked it up in its environment and was sick with something else?
Several big cats at the Bronx Zoo were sick, they and their keeper are recovering fine! There's a paper on bioArXiv that supposedly documents infection in domestic cats; I haven't read it properly but I think it involved three cats and they were exposed to very high viral loads. It's not gone through peer review so I wouldn't put a lot of faith in its results yet. I have yet to find any reliable reports of household pets being infected by ill owners, so if it does happen it must be vanishingly rare. But don't rely on your cat to keep you safe from covid-19!
