I would recommend making arrangements for the body beforehand/having someone else around to take care of the immediate 'aftermath', as morbid as that is to think about. You aren't going to be in any shape to handle any logistics and seeing her body without 'her' in it WRECKED me.

Hmm so the vet doesnt deal with that? what do i actually do to make preparations, as theres no pet cemetaries that Im aware of?

Vets usually have information about cremation services. Some vets offer them on site, but some don't - check with your vet. There are also memorial options (urns, paw prints, etc.) that you might want to look through now as kitty is alive, because trying to decide how you want to remember them right after they go is just asking for ugly sobbing. Also figure out your budget because the last thing you want to do is pick something in the throes of grief and be unable to afford it. "I can't even afford to remember them properly" - > More crying.
