Our eldest cat has been quite aggressive towards me for a very long time and I'm not sure why. He has been desexed and absolutely worships my husband but any time I even come near him he constantly growls, hisses and swipes at me! He was totally fine when he was a kitten but I think it got worse as he got older. We rescued him at about 2 weeks of age when he was abandoned by his mother and makes me think his behavioural problem may stem from this? There are some times where he seems fine with me and enjoys a little pat but the majority of the time he's in a bad mood. Any idea what could be causing this?
