Aversives often provide a good method for discouraging your cat from doing things you don't want her to do. Keep in mind, however, that it is important that you provide your cat with an alternative that is rewarding and convenient. There are several different methods of aversion that can be used, including textures, smell, taste and the element of surprise. Finding the right aversive that works will depend on the individual cat. Often times, you may need to try several different methods before you determine the one that's best.

Aversives that involve texture are good for discouraging your cat from certain areas, such as keeping her off furniture or countertops. For instance, shelf paper makes a good aversive when used with the sticky side up. Other good aversives include double-sided carpet tape, a heavy plastic carpet runner with the pointed side up, and heavy foil.

Aversives can also involve smells. You can soak a cotton ball, washcloth or rag in an unpleasant substance, just be sure that it is placed on heavy foil or plastic to protect upholstery, furniture and the like. If you use smell aversives outside, such as in your garden, you will need to reapply the substance on a daily basis. Smell aversives may include the following: aloe gel, citric odors, insect repellent (those safe for young children are generally safe for pets), and some colognes. Some types of muscle rubs may work on some cats, however there are cats who react to menthol the same way they do to catnip.

Aversives involving taste can be good for a variety of things, particularly discouraging your cat from eating or chewing your plants or other items. Because some of these products may damage items like furniture or floor finishes, be sure to first test them on an inconspicuous spot. Taste aversives can include the following: aloe gel, bitter apple spray, cayenne pepper, citric odors, some hot sauces, and some muscle rubs.

Aversives involving the element of surprise stop your cat in the act of her bad behavior by startling her. For instance, you can fill an aluminum pie plate with water, beans or pebbles and balance it somewhat precariously on an item like your countertop. There are also products that you can buy like a motion detector that reacts with a startling noise or a scat mat which gives a very slight electrical shock. There are also surprise aversives that you control, such as a squirt gun, water bottle, whistle, loud air horn, or a soda can filled with coins. Once you have gotten your cat's attention, be sure to offer her an alternative. Surprise aversives are best not used on fearful cats and should only be attempted as a last resort.
