I guess I'm not as nice as everyone else, I'm for finding the cat a new, more loving home. From what I read, it sounds like these are people that really don't care for the cat. I think it would be save to say the cat doesn't get the right vet care / love she needs

Your the one who lives there and see the cat and it owners, so you are the only one who knows what really going on. So I guess if I where you I'd ask myself some ?'s.

Is the cats safty/life at risk?

Do you belive the cats is being abused, in anyway?

Do you think the cat needs vet care?

Do you honestly belive that the owners will even care or miss the cat?

It's the same as a child, if you belived a child was uncared for, unloved, abused, you know you do something about it. No question about if it's right are wrong, right? So why not do the same for the cat?

If you know you can find her a good loving home, I say do it. For the cats sake. Sometimes you have to bend the rules a little and find that gray area between right and wrong.

I did this once with a dog that always came down to my house, I knew his owners and knew how bad the dogs life was, so one day, I keep him. Told the man who's dog it was that he wasn't getting him back and if he tried, I'd make his life a living H#$l. He left the dog with me. Duke was with me 5 years and was one of the best dogs I have ever had, it was as if he was thanking me for saving him, so he gave more back to me then any pet could.

Good luck to you what ever you decide.
