We feed a stray cat. He isn't really a stray, because we have seen him go

aren't working properly

How have you diagnosed that?

IOW, I
would prefer to just catch him, put him in a cat carrier, call the roving
vet, get him operated on, and let him go without ever telling anyone else
about it. What do you guys think?

I think removing his thyroid is a death sentence if you are not
prepared to give him thyroid supplements the rest of his life.
