We've had a lovely cat coming to see us lately which I assumed was stray as had no collar, so I have been feeding him (I know, I know that's a big no no but I honestly thought he must be hungry as he was hanging around a lot). But in hindsight, he's very clean and friendly so now I'm questioning myself, and although no collar a quick google tells me he could be chipped which is obvs not visible to me. So.... you guys with chipped cats, so they also have collars? Wondering how likely it is that I've pissed off a family by feeding their cat as he's here ALOT now.
