I agree with the others, he should have found himself another apartment. You don't leave your children behind, wether they have 2 legs or 4. If I were you I would tell him what is going on and make him pay to put an ad in the paper to find him a home. But if you choose this option ask them that they keep the animal inside and charge an adoption fee. This stops people from taking free cats and giving them to there pitbulls for training. Normal fee is 25 to 50.00,

Other options would be to check with your local rescue groups abnd see if someone can take him. Most of the time they are full, but you can always try. I am so sorry that this is happening to you, i wish it would have worked out . There is a product called?????I think soft paws,? You put them on the cats nails so they can't hurt the other animal. or scratch your furniture.

Another option is putting him in a cage, and making he will back off, but he will have to stay there awhile. and trying to reprogram him,

I know there was a post here awhile back that teaches you how to reprogram them, I know it starts with putting one cat in one room and the other in another room, and then in a week switch them.
Anyone know the post or link to that site?

well good luck on your quest, it is a hard and difficult one for anyone. I hope it works out for the best for you.....keep us update
