When dealing with objectionable cat "crimes" like behavior problems, cat lovers like to use rewards such as positive reinforcement techniques as a part of behavior modification. There are different kinds of reinforcement and it's helpful to understand the different techniques and how they work to help with your cat behavior problems.
Positive Reinforcement
Positive reinforcement means the behavior you want happens as a result of you adding something pleasant (positive) that the pet likes. You can use a smelly cat treat to lure kitty into a "sit," for example, or reward with a catnip mouse or other favorite cat toy when she jumps off the dining room table upon command.
Bad timing (giving the treat too early or late) confuses the pet. She needs to receive the positive reinforcement at the right moment so that she understands it's in response to the desired behavior. Otherwise, she won't have the incentive to repeat a desired behavior.
In order for positive reinforcement to properly work, it must be contingent upon the desired behavior actually taking place (don't reward unless she performs what you want!); it must be associated with the behavior; and it must be used consistently.
