I'm so very sorry to hear this, what a tough decision for you to make!

But I think it's the right decision - for him, for the other cats in the household and for their humans. As sad as is it, we have to accept that some cats just are like that, and that they cannot handle other felines in their environment. I'm sure you tried everything you could and did your best to help him adjusting to the group, but he doesn't seem to be comfortable with that arrangement.

It's a heartbreaking decision and I'm not sure if I would have the strenght to decide that myself, but I'm sure you'll realize you did the right thing once Oliver has found a single-cat household where he's happy and pampered. Best wishes to all of you,
