I hope you are being ironic, but there have been numerous scare stories about animals spreading Covid and I dare say some owners have been very frightened., possibly even to the extent of giving up their much loved pet because of the paranoia regarding infection.
There was a thread a while back and I found this on it
The RSPCA say :
" In most cases we don't know why pets are abandoned but it's really important to remind people that there is no evidence to suggest that Covid-19 can be passed from pets to people ."
