i recently adopted two kittens from the shelter. they are 6 months old and very destructive. they have knocked off and broken some very heavy and valuable things from my mantle...they really are out of control with their behavior and causing a lot of stress in the family. they are little lovey kitties for the most part when i am home wiht them but the trouble starts during the hours when we are at work or while we are trying to sleep. one is an abby and if he is not knocking things over in the middle of the night then he starts talking non stop around 5 am so i will get up and feed him(if i lock him out of the bed room he just keeps tapping at the door and whining out side of it)....can't keep them off my tables, counters, flower pots. my perfect 4 year old cat whole has always been very good is now picking up their bad habits..as i was eating dinner last nights she decided to get up and LAY on my dining room table!!! i can tell them no, and squirt them with water while i am there and see it happening but like i said the problem mainly is going on while i am sleeping or not there.. any suggestions??
