Damn! My cat is 17 years old and fat. What shall I tell him??
Goodbye?
(S\eriously, it's an oddity, very rare so far. Unfortunately, other things will bother a seventeen year old kitty. We had one until fairly recently. I miss him.)
ETA: maybe not so rare... I saw a paper (forgot where) purporting that domestic cats can acquire COVID-19 from owners and pass it on to other cats and people. Dogs too but much less. If the work is correct.
