I'm sorry for your loss. I can't sleep right now because I'm having all these questions too. For us it was an accident. It involves my son and not to get into a ton of detail, but I just have a ton of questions for him, but I don't want to ask because I don't want him to have guilt out on top of the pain he's already processing for himself. I wonder what might have going through my cats mind, do cats have those kind of thoughts? Was he feeling betrayed or unprotected by us? It's killing me to think all of this stuff. I have been reading a lot to find out how cognizant is a cat. I just want this to go away and go back to before it happened.
