Hi. A little back story on the feral cat I'm taking care of. I moved into a house that a lady I know was previously living. When she moved in over six years ago there was a cat living under the house next door. She started feeding him and taking care of him (I don't really know if it's a he or she). He has good shelter and I feed him everyday, he lets me pet him and hold him. I want to try to bring him indoors to be a indoor/outdoor cat. I have a 5 year old male indoor/outdoor cat now. The feral is very nervous when he is away from the hole underneath the neighbors house. I really want to bring him in for the rest of his life so he can be warm and enjoy his elder years. It gets very cold where I live. It's already been below zero many days this winter. I'm looking for some input on bringing him in? Is it a good idea? Thank you for your help.
