Joanna, yes I agree, bringing another cat into the mix is very problematic. I figure my only hope is to get a very young female for my male, and hope that they bond because the kitten won't leave him alone, and because he's interested in her because she's female. He's only about 4. Neutering doesn't erase their interest in girl cats, especially since he was a rescue, who apparently fathered kittens before he was "fixed".
