aggressive behaviour

Question
My boyfrineds cat Rolex is 5 years old and has become very aggressive as time goes by. I will say this he is home alone alot and sees his owner on a daily basis and myself a few times a week he is not neglected by either one of us and is shown lots of attention and love by us (he sits on his owners lap for hours and grooms me every chance he gets but when a visitor comes to the house he turns into a very mean cat hissing and spitting batting I can,t say he has tryed actually biting yet! how do resocialize a cat with other humans (we don't get company often)

Answer
Paula,

There is probably some jealousy, some territorial issues involving 'protecting' you and/or your boyfriend from 'strangers', and some attitude thrown in.

At that age (he is approximately 36 years old in human years) and "set in his ways" and routines and it will be difficult to turn him into a lovebug to others.

Don't try to force him be friendly. Have your company ignore him and not try to pet him or hold him. If he's curious or wants to be friendly let him come to them. If not, let him hide. That is his personality. If he becomes aggressive with company on his own, then I would put him in another room until they leave.
