I have had pets that were more trouble than they are worth. Elvis is nothing like that. One time feral. been through a lot out there... went through a couple of owners. Last years with me. Trying to make his last days comfortable. Sit outside (he is an indoor cat) with him in the sun for an hour. Gave him some milk which I never did but he is not eating so? what the hell.
Fucking vet has not even returned my call. Rather he die here than on some table in a vets office all freaked out. So long as he is not in pain of course.
Against the law to bury a pet in the backyard. I would never break the law of course.
