don't go right for the pet, hold out your fingers and approach him, let him sniff your fingers, and if he rubs against them, give him a little scratch behind the ears and say loving things to him
I can't point to anything specific but I get the impression that he's in bad health, and I can't get him to the vet before tuesday (and that's if I can wrangle him on tuesday)
officially diagnosed with ADR (aint doin right) and maybe put on an antibiotic just in case (which they might not for him because hes not really handle-able yet) and then you wait for like. a week and a half. and it'll run itself out.
yeah honestly he seems mostly fine hes hangin out and watchin birds on tv i think hes just sneezy because all shelter kitties get a little sick but he'll be just fine
