ask your vet for mild sedatives for his visit.
otherwise, fuck you, veterinary staff is trying to prevent ourselves from catching covid. we are already over-worked; if we get sick, then the whole clinic has to be shut down. and then there will be no one to give your cat its fucking vaccines. no animal enjoye being at the vet. if your vet doesn't practice fear free or provide at least anti-anxiety meds or sedatives, then find a new vet. We aren't going to put our health or our jobs at risk for anyone.
