Well, here is a bit of an update to my last post. So I hear Dot outside meowing loudly, nothing new I thought. I ignored it & started to clean my room like planned to see if that would work. While taking out some trash I found her, dead. She was really fresh still, hadn't gone into rigamortis. I've thrown her out before & she has ran off before so it's not like being outside for 24 hours killed her, neither did I. Though, the guilt is there but probably for no good reason I know. She was dry, so she found somewhere to huddle down last night. I guess it just makes me guilty that I ignored her death cries. I found a little private spot & buried her underneath a ton of leaves since I don't own a shovel. I do feel a bit better knowing that I was trying to make her feel better with the new cat litter, water thing, better food, cleaner room but still, guilt. I also know I couldn't have taken her to the vet even if I wanted to, I don't have that kind of extra cash. Sigh, guilt, I was pretty angry with her when I threw her out, smacked her on the head & yelled at her. I guess it's just always bad to have things end on a bad note, no matter what you were trying to do. Blah, this sucks.

Aww I am so sorry ;( RIP Dot. You couldn't have known that it was her time to pass, it sounds like she went really peacefully. You were good to her it seems and loved her lots. It still sucks though....however, I do not see any reason to be guilty- besides guilt is bad, you cannot change what happened. I hope you feel better
