Hi, you were all helpful to me in introducing my kitten, Harry, to my 3 year old princess Isabelle. She was NOT interested in meeting him, although I kept them apart for seven weeks (no small feat, trying to give each one enough attention). They seemed fine at the introduction, although Isabelle did continue to growl and hiss at him. He, at that time, was 3 months old. He had a growth spurt and now is as tall as Izzy (he's 4 1/2 months old) and very strong, and he stalks her and attacks her INCESSANTLY. She screams and runs away, she fights back fiercely, and she hides. Her life is he**. We try to re-direct him, and he is NOT interested in anything but her. I met a woman who had the same situation and she said after TEN YEARS it is still the same, her female, older cat lives in a constant state of harrassment. TIPS please!!! I love them both... he is scheduled to be fixed next month. We do put him in 'his' room at night, and Izzy snuggles in bed with us happily, so she gets 8 uninterrupted hours of sleep - does this ever work out? Sorry it's long, once again I'm at my wits' end....
