If you're a cat, a low-hung bird house looks like a buffet; a bare patch of soil looks like a litter box; and standing water looks like the ideal spot to stop and take a drink. Try to see your yard as cats see it, and remove the things that make it attractive to them.
02Plant Things They Don't Like
Cats aren't fond of rue, lavender, geraniums or coleus canina. Work these plants into your landscape design to create a garden that's pretty to look at, but repellent to cats.
03Remove Plants They Do Like
Have mint or catnip growing in your herb garden? Consider replacing them with something else. Cats are drawn to both. If you feel bad about tossing your plants, you could always gift them to a neighbor who has cats.
04Save Your Scraps
Keep your citrus peels and coffee grounds and spread them throughout your garden to send cats on their way. They hate the smell of both. A nice benefit to this approach: used grounds happen to be a terrific fertilizer for acid-loving plants, and slugs hate citrus peels, too.
05Mulch with Poky Materials
Replace your bark mulch with pine cones, holly leaves, rose clippings or rock chips. They don't feel good underfoot, and will encourage cats to spend their time elsewhere. If you'd like to keep your bark mulch, just add a thin layer of the previously mentioned materials on top (egg shells work well, too, and they're an excellent fertilizer).
Trying to keep cats off your car? Drape a spiky plastic door mat or runner on the hood when you park, until you've broken them of the habit.
Fill in the bare spots in your garden with more plants, decorative rocks or garden statuary. Exposed soil is just begging to be used as a litter box. Have certain spots in your yard that have become the bathroom spot of choice? Lay down a piece of chicken wire or a spiky plastic doormat. They won't do cats any harm, but they won't feel good to walk on, either.
Clean up any brush piles and clutter in your yard; cats will see them as the perfect place to hunt mice. Then, make sure all of your bird feeders and bird houses are too high for cats to get to easily.
08Feed Your Cats Indoors
If you have cats of your own, keep their food in the house. An outdoor food dish will attract neighborhood cats – and plenty of wild animals, too.
09Hose Them Down
Train cats to stay off of your porch furniture and out of your vegetable garden by spraying them with water whenever you catch them in the act. A few sprays with a garden hose or a squirt gun will quickly modify their behavior.
10Unmark Their Territory
Dealing with a neighborhood cat who insists on marking your doors as his territory? Reverse the behavior by giving your doors a thorough cleaning each and every time he does it. An enzyme cleaner will remove all traces of his markings, so he's less likely to come back and re-mark his territory again (cats re-mark any spot that they can smell their odor on)
11Remove Sources of Shelter
Make sure feral cats aren't sheltering in your yard by securing your shed and any other outdoor buildings that they may be able to get into. If you have a crawl space under your porch or your house, also make sure these areas are secured.
How to Repel Cats
You don't have to have a problem with cats to have a problem with them using your garden as a litter box or them using the hood of your car as a lounge chair. In fact, you might even be the owner of the cat who's causing you problems. Whatever the situation, the following tips will help you to safely (and humanely) repel cats from your yard:
