1) cayenne pepper on top of the dirt around the plants. It only takes a tiny bit.
2) You might need seperate cat box for each cat. some cats do not like sharing.
3) Keep the cat boxes clean.
4) Animals respond to positive reinforcement much better than negative reinforcement.
5) All it takes to let a cat know he is acting bad is a stern voice.
6) And cats are different from dogs in that the INSTANT they stop doing something wrong you must stop correcting them. For example if he is up on the dining room table you can talk sternly with him. But the instant he gets down off the table you must be nice to him.
7) I taught my kitty to
play the piano with only positive reinforcement.
