Please don't feel bad, sweetie. T&P's mom is right, how were you supposed to know that Oliver wouldn't get along with the other cats in your home? Apparently, the person who thought he got along with other cats was mistaken, or just like my Sam from college, maybe he was ok with cats in neutral territory. You tried, and it's not your fault that he would be better as an only pet. You're the best kitty mommy around, and it shows, because you know your babies so well, and you know that it would be better for all 6 of them for Oliver to be an only cat. That in itself is a tough decision, but made out of nothing but love.

I'm here for you, chica, if you need to talk
**hugs**
