We have had cats for the past 20 years. Obviously not always the same ones and a mix of 3 usually. They have all mixed really well until we took on the last rather cross girl, totally unintentionally as you do with strays. we now are back to a boy and the cross one. Both neutered. Would love to get a kitten but worried that cross kitty wil be awful again. She bullied the previous girl to distraction. Is it worth the risk. Have had loads of mixed advice...cats don't know age, girs dont get on etc, any ideas much appreciated
