I have two cats the same age, and the other one has been trained easily. But his brother is constantly doing things like he will jump up on the worktop several times a day, play with my corded secure flat entry phone, rip up bin bags before I've took them out. He rips up the litter tray liners and I can't use them. He tries to climb out the window if I leave it open. He knocks over the same lamp over and over again. I think my other cat is smarter and just understands no. I don't know what to do I'm frustrated having to deal with the same things over and over several times a day and I get really frustrated and annoyed with him. Will he grow out of it ? He's 4-5 month old
