I have a six year old brother and sister cat which are of unknown parentage. They were found on a sidewalk at an estimated age of 2-3 days old. They were fostered by a mother/daughter team in my town and put up for adoption when they were about 10-12 weeks old. They have been very easy cats, quite wonderful in fact, until more recently when Timo, the male, has gone from pesky to bullying me with respect to food. He is a very large cat weighing about 17 pounds or more. He is very slightly overweight, his sister just a bit more than slightly overweight, so I try not to feed them in a way that will lead to weight gain. But apparently Timo doesn’t think he is getting enough food. He used to pester me by walking on me. Now he jumps on me, usually landing on my stomach. Hard! Repeatedly. Or he will leap over me, narrowly missing my head, my glasses. He head butts me. Hard! He walks all over me. He just will not let me alone! I’ve taken to pushing him away, sometimes fairly roughly, but to little benefit. I if he does stop he’ll sometimes lie on my arm, pinning my arm down, and then stay still for a short while and I will pet him and praise him. But that doesn’t last. At this point I will often get up and feed him. I do make it a point to not respond to his bullying until it stops before I feed him. But it doesn’t work very well, if at all. I’m lost as to how to train around this problem. Would appreciate suggestions.
