Sorry to post again and i know its already been said, i just wanted to say, if i were you i would definitely be getting onto the vets tomorrow morning, and demand they tell you which crematorium your cat was taken to, and there number. Im sure they HAVE to tell you this. Then you could ask for his body to be returned, or you might have to pick him up i dont know. Sorry if its not what you want to do, I'd also understand if you just wanted to let him go rest now instead, just giving you my opinion x
