The help I am looking for is how old are the cats when they stop playing so hard that they knockover stuff!!! Every morning I have about 3 hours of work to do putting the house back together again!!!! It is a good thing that almost everything in this house is worn out b/c if it wasn't it would be soon!!! The cats are very hard on the house while I sleep!! When I got Bambi she was 5 months old and she was never hard on the house at all. She was the smartest dog I ever knew. You only had to tell her one time and she ever did it again as long as she lived!!! My German Sherphard was smart but there were times you had to tell him again b/c he forgot........ I got my GS dog when he was 7 weeks old and by the time he was 4 months old which is what the kittens are, he was a super dog!! Never doing anything wrong in the house!!! So dear friends, how long before it is easier to live with the kittens??????
