Hi all please excuse me if I put this question in the wrong place but here goes, I just recently lost my cat, Ive had for a really long time since I was young, he was very old and stuff, and just a couple days ago he disappears from my house, which i thought was weird because he was an indoor cat. I later found out that cats run away from home to go die peacefully and this is just about the saddest thing ive ever heard, im still kinda depressed about it, but my question is can animals become like spirits too? like a human being can become a ghost if it dies with unfinished business, I want to know if my cat left peacefully knowing that we gave him a good home and saved him from the shelter I wish I could thank him for being there in good and bad times, I loved my cat and I miss him dearly
