fixed cat fights

Hello

Do fixed male cats sometimes fight the same way an unfixed male will and chase other cats off their yards etc... DO females ever do this?

Yep. My cats are all fixed. And Tinga is the worst. He will chase any cat off his territory. My cats also gang up on other strange cats in the garden and surround them. It usually ends up with Niko walking down the middle, and cos he is so big and fat the other cat runs away.
