I recently got a male kitten. He was 7 weeks when we got him and he is now 7 months almost 8. We had also already had a 2 year old female cat. She was lovable and very at peace. However, the new kitten we got is something I have never seen. He attacks my 2 year old cat all of the time, she can barely walk by him. And he is constantly up on furniture knocking anything down and clawing at screens and my couches. We also have 3 cat scratching posts placed in 3 different rooms but he shows no interest. I need this to stop. I especially need him to stop attacking my other car. Oh and he loves water, I tired the water guns and he loved it. He loves baths. Any suggestions?
