I just got a female kitten about 8 weeks old. I have a indoor/outdoor male cat about 10 years old that keeps hissing at her and growling and seems as if he is going to lunge at her until i step between them. He has grown up with two other cats, both female, though one of them has just passed away. The female, also 10 years old, seems to be adjusting to the new kitten being around, but i am scared the male is going to kill her. Are male cats that have been raised with other cats likely to kill or hurt a female kitten?
