I will try to answer all of the questions so far:
We have had the cat since he was fairly young (about 6 months or so). A friend of mine (female) raise Victor since he was a kitten. When we got him, my husband and I were already together, so it wasn’t like hubby had the cat and I invaded their perfect relationship.
I have no idea what triggered his behaviour, but it has gotten steadily worse in the past year and a half. For example, he used to only attack my hands. Then he started attacking my bare legs when I got ready in the morning. Recently he has started attacking my legs, bare or clothed. He follows me around howling and yowling with the occaisional growl for good measure.
I usually don’t try to touch the cat, since it obviously does no good. But if one of my hands comes near him (while I’m sitting on the couch, for example, and he jumps up on the end table next to me), he will attack. My husband can pet him fine. In fact, I can pet him so long as he thinks it is my husband (for example, hubby will be petting him on the couch and Victor’s eyes will be closed. I can then take over for a very brief period of time. I assume the smell tips him off). Once he realizes who it is, he bites.
Let me clarify that I am not hitting the cat hard, etc. It is more defensive “batting away” type movement with the occaisional harder smack if he really just won’t leave me alone.
We tried using catnip (it sedates our other cat. We actually hang a little baggie of it around her neck when we clip her nails), but Victor becomes more aggressive, particularly to the other cat (who is just trying to enjoy her high).
The cat knows that my husband will “protect” me, so he generally reigns himself in until we are alone together. If he does bite me while hubby is here, he runs in for a quick nip then dashes under the bed to hide. He knows he is not supposed to attack me.
Victor will attack from any direction. I’ve tried staring contests with him in the hope that it would establish my dominance or somesuch, but the lesson seems lost on him.
I will definitely try some of the tactics listed here, such as the scruffing and sheeting. I’ll let you know how it goes.
In the mean time, please continue with the suggestions and questions!
