The most obvious thing to try is to simply remove the object so that the cat can not get to it. When that is not possible, limit the number of objects the cat wants to chew to as few as possible and use tast aversion on them.
Taste aversion is the use of something that tastes really bad on an object that the cat should not chew on. To help this technique be most effective, start with a product that tastes REALLY bad. There are commercial products available, or you can use a hot pepper sauce. Let the cat smell the liquid and immediate squirt 1 or 2 tablespoons in its mouth. The resulting reaction should be lots of drueling and negative responses. Now coat the object that should not be chewed with the liquid.
The reason this works best can be thought of in human terms. If you eat Chinese food and then get sick, it is a long time before you even think of eating Chinese food again. You have made the connection between the taste and smell of the food with the unpleasant event. That is how taste aversion works for the cat too. They remember the smell and the taste that goes with it and the very unpleasant experience of getting the bad stuff put in their mouth.View Thread
