To have his cats put to sleep?
One of them has at least two chronic health conditions, and another appears to be quite ill, but the vet doesn't know exactly what's wrong. He's spending a small fortune, and is in a constant state of worry over it. The cats' quality of life can't be good. I'm sure he'd think I was horrible for suggesting it, but I really think it's time to consider it. I'm surprised the vet hasn't brought it up.
