I need to train my cats to not go in the kitchen and to not get on certain furniture (If you are wondering why go see the thread "Hubby is Compromising" in the Cat Lounge). I know of all the techniques: water bottle, jar of marbles, citrus spray, double sided tape, throwing a rag by them (not at them) to startle them. My concern is do you use a variety of them or do you just stick to one? Do I use just one for everything, a different one for each thing or a variety of them no matter what?
