i can't stand that look on their face when they go white. Every cat i've had to put down has been in a state, it's like butyo. In the end, no matter how attached you are, it's worse for the dog. I think there's less of an emotional attachment from a cat. There's still something about the cat that sits on you cause it wants to be warm.

It's like saying he shouldn't have friends or family
