Training Strategies
Since cats, unlike dogs, rarely do things merely to please their owners, you will need a feline-based system of positive reinforcement and possibly some form of aversion stimulus in order to achieve a change in your cat's behavior. The best way to encourage a cat to continue a behavior is with an immediate food reward, whether a full meal or a tasty treat. If at the same time you say, Good! the cat will come to associate the word with a positive event, even when food isn't forthcoming. Anything your cat loves will also work a good scratch behind the ears or a play session with a favorite toy may work as well as a food treat.
Many cat owners try to discourage their cats from undesirable behavior with sprays of water from a plant mister, loud shakers or any startling sound such as a hand clap or a whistle. If your cat is jumping onto the counter and you stop him by spritzing him with water, in actuality you are reinforcing jumping off the counter when the real problem is jumping onto it. While spritzing and other such methods can often discourage unwanted problems temporarily, they may also cause additional problems. Some cats actually like getting sprayed and chased. They think it's a game. For them, spritzing provides positive reinforcement for the undesirable behavior, which is then likely to increase. Other cats, particularly those that tend to be excitable, are threatened by such methods and become defensive, which can lead to serious aggression problems. Aversion methods that don't frighten or excite the cat are much safer. Putting sticky two-sided tape on the counter, for example, should provide enough discomfort for most cats to decide that the surface isn't a fun place to explore. And this method works whether you are there to witness the behavior or not. When you are present and see the unwanted behavior beginning, say, "No!" in a stern tone; your cat may, after a while, obey the vocal command alone. Never hit your cat. Injury can result and physical punishment won't change his behavior. The cat will simply become afraid of you and the stress may provoke further misbehavior. Reward your cat when he performs a desired behavior in place of the undesired one. Such a payoff will usually clinch the deal.
Some household items may simply be just too tempting for your cat to stay away from. Put up physical barriers to areas and surfaces you want your cat to avoid. For instance, if your cat is always getting into the garbage, you may have to get a container with a heavier or tighter-fitting lid. If he opens and enters cupboards, install childproof latches. After a while, the cat will probably lose interest in these forbidden locations and avoid them of his own accord.
