This morning was very hard for me. Had too take one of the cats in to the vet too be put down. We'd had her over 20 years, so needless too say, we got pretty attached. Man, this sucks !!!!! She was a very loving animal, in good health, but she wouldn't use the litter box anymore. We just couldn't have her pissing in the carpet. I'm at a loss for words. I feel like such a heartless bastard. We've tried about everything the vet told us, and nothing worked. I feel guilty, she trusted me.
