I know how you feel man I just lost one of my cat's this morning after he was holding on-to he's last breath's for 3 days. I wanted him to stay with me, told him I was here for him so he should stay, but I also wanted him to go, to stop suffering as I also felt selfish for not wanting him to give up on life, but I guess it was our love that I didn't want to lose, he looked into my eyes often I only wish I knew what he wanted to tell me, in the end I expected too much and I'am sorry.
