Not at all, I have taken in several cats that have followed me home over the years. I am currently feeding a cat every day and have made a shelter for him too. Someone obliviously dumped it because during the summer he was covered in fleas and isn't neutered. I can't take him in because I already have 4 cats and all the no kill shelters are full. So for now until I can find a shelter with room, he has food 24/7 and a warm shelter he can sleep in and get out of the snow/cold. I also took care of his fleas and go out and see him every day to get him more use to people petting him.
