That poor gray cat. Bless you if you help him. We have an older adoption and she was somewhat mistreated from what I can figure out. 3 months in and she's very comfortable with me. I think a man might have figured in on her mistreatment because she took to my wife right away and avoided me. Well, the plan was for her to have more of the companionship, so it's working out fine.
Let me introduce you cat folks to a budding forum:
