My cat bender is about 7 and a half months old, and i have noticed some weird behavior lately. he is supposedly neutered,( i got him from the humane society) and my other cats ARE spayed. a few days ago i saw Bender on top of Izzy (1 year old) biting her back, she was not happy about it. he was aggressive. i have been watching them lately and he does it regularly, not excessively though. is this just something a male cat will do? or maybe something didnt go correctly when he was neutered? i dont really know what to think. if anyone knows what this behavior means or why he woudl do this or what to do about it, let me know! thanks a bunch.
