Discouraging Free-Roaming Cats

Many people have a problem with free-roaming cats who hunt wild birds as they feed or nest in their yards, who use their garden as a litter box, or who upset their pets by invading their territory. You certainly have the right to enjoy your yard and the birds who visit it. However, it’s your responsibility to solve your free-roaming cat problem humanely.

Why Are They Picking on Me?

Although a destructive neighborhood cat can be frustrating, don’t take it personally. The cat isn’t acting out of spite or picking on you for some unknown reason. He’s behaving naturally. The problem, of course, is that he’s doing so in places you find inappropriate. The solution lies in making those places undesirable so the cat will behave naturally somewhere else.

Unless they’re literally starving, most cats won’t eat birds, but they do enjoy the “thrill of the hunt.” Cats have preyed upon birds for thousands of years and there’s no foolproof way to discourage this natural instinct.

Another natural feline instinct is to defecate in areas where the cat can cover his scent by burying the waste. Therefore, a cat that spends most of his time outdoors appreciates the soft, pre-dug dirt of your garden—or your child’s sandbox—as a handy toilet. When a cat naps on the hood of your car or in the center of your flowerbed, he’s simply sunning himself in a nice, warm spot and doesn’t realize the damage he’s doing. He won’t connect your negative reaction with the place where he naps, and although he may learn to avoid you, he won’t avoid the place or stop the activity.

A free-roaming cat may approach your window or patio door and challenge your cat or dog through the glass with blatant body language and/or vocal insults. The best way to protect your pet from this type of situation is to keep the outside cat away from the areas that your pet can see by using the techniques described below.

Of course, the ideal solution is for all cat owners to keep their cats safely confined. Unfortunately, not all cat owners are willing to do this, so you’ll need to take steps to solve the problem without harming the cat, the birds, other innocent animals, or your yard and garden. Because each situation is different, you may need patience and ingenuity to find the appropriate deterrent through trial and error.


Repellents and devices designed to startle the cat “in the act” will work best to condition him to avoid the area. Never use poisons. Not only is poisoning animals inhumane and illegal, it’s not an effective solution to the problem. Poisons will only rid you of one “pest” and won’t deter any others. You’d have no way of knowing or controlling who might find and ingest the poisonous substance.

Check with any pet supply store or garden supplier for commercial cat repellents. There are a variety of natural oils (available at health food stores) that some people claim have worked in deterring cats from their property including eucalyptus, citrus oils and lavender. Keep in mind that the effectiveness of any repellent will deteriorate with moisture and/or time. Whether you use an aromatic oil or a commercial mixture, you’ll need to re-apply the solution after each rain, heavy dew, or watering. Check with your garden supplier to be certain that the solution you choose won’t harm plants growing in that area, especially if you use fertilizers or other soil additives.

“Surprise” Devices

To teach a cat to avoid a specific area, you must make that area unattractive to him. The best method is to surprise the cat “in the act” but without the cat knowing that you are the one administering the surprise. Simple devices can be used to effectively “booby-trap” the area that a cat has found attractive.

  • Sound and Movement: Scatter dry beans, macaroni, or birdseed on a metal tray; disposable pie pans or cookie sheets work well and are inexpensive. Balance several trays along the fence, porch or deck railing, the windowsill, or around the edge of any vehicle where the cat jumps onto the surface. Birds can still land safely if the trays are balanced properly, but the weight of a cat leaping onto the surface will upset the tray.
  • Texture: To keep a cat from jumping onto flat surfaces (railings, vehicles, or decks), criss-cross double-sided tape onto a piece of sturdy plastic—either a heavy, plastic drop cloth or a vinyl tablecloth would work well. Drape the plastic over the surface, and secure it with cord, or at least one weighted object, to keep it in position. The sticky tape is annoying to the cat (without causing pain or panic), and the slick plastic not only rattles but also offers no foothold. An alternative to sticky tape would be to use a plastic carpet protector with the knobby side up.
  • Water: This method works especially well for those areas where birds feed on the ground or where cats are using a garden area as a litter box. When the temperature permits, turn on a water sprinkler during the usual time of disturbance (which may be dawn or dusk if the cat is on your property to hunt).

Humane Traps

Don’t use anything other than a humane cage trap designed to lure a cat into the cage with food, and to safely contain him until he can be moved to another area. Most animal control agencies and humane societies loan or rent out these traps and some will even deliver and/or pick them up.

To trap a stray cat, bait the trap with canned cat food. Place the trap in an area that’s sheltered, as much as possible, against the weather. Although you may hear some alarming noises when the cat realizes he’s trapped, he’s only scared, not hurt. If the cat is confined with no access to water or shelter from inclement weather or predators, it’s important that you remove the trap from the area immediately. Using gloves to prevent scratches or bites, put the trap in a protected area until you can take the cat to an animal shelter (which should be as soon as possible). Please don’t release a stray cat. This will only cause further overpopulation problems.

If the cat is unknown to you, take him to your local animal shelter. He will be cared for there and his owners will have a better chance of reclaiming him. If he is not reclaimed, but of good health and temperament, the shelter will try to find him a new, loving home, at which time you may be able to take the cat yourself if you wish. That way, you can keep him safely confined in your home, where he belongs, with you.
