Why Cats Keep Coming Into Your Yard

Before learning how to keep cats out of your yard, it helps to understand what may be attracting them in the first place. According to Dr. Humm-Beatty, some of the most common attractants include:

• Food and water sources, such as pet food left outside or standing water in containers
• Garbage or compost bins that provide easy access to scraps
• Shelter that makes them feel safe and protected
• Bird feeders, which can attract both birds and the predators that follow them
• Bird activity itself, since cats are natural hunters
• Other animals, including pets that may draw curiosity or territorial behavior

"Cats may also be drawn to your yard because it offers soft, loose soil that's ideal for digging and elimination," Dr. Humm-Beatty explains.

Cats are also highly territorial and tend to follow consistent outdoor "routes." As they travel these paths, they mark and detect scents left by other cats, reinforcing repeated visits.

"If unneutered or stray cats are already moving through a given area, that scent trail alone can encourage them to keep returning," she adds.

Smells Cats Hate

"Some scents that cats tend to avoid include citrus, spicy odors, vinegar, citronella, certain essential oils and cleaning products, other animal scents, dirty litter boxes, and smoke," says Dr. Hilary Humm-Beatty.

While some of these smells may also be unpleasant to humans, they can be especially powerful for cats-and may be useful when considering natural deterrent options for your yard.

"A cat's sense of smell is thought to be about 14 times stronger than a human's," Dr. Humm-Beatty explains. "Humans have around 5 million scent receptors, while cats have approximately 200 million."

Cats also have two scent-detecting systems: their nasal cavity and the vomeronasal organ, located in the roof of the mouth, which helps them process and interpret chemical signals in their environment.

Motion-Activated Sprinklers and Other Humane Deterrents

Besides removing plants and other attractive items from your yard, you can repel cats with motion-activated sprinklers, alarms and even plastic mats. Dr. Humm-Beatty says other humane cat deterrents include:

• Motion-activated sprinklers. While pricier than other humane cat deterrents, Dr. Humm-Beatty says that these sprinklers are effective because cats "do not like getting wet." "These sprinklers are activated by the heat or motion of an animal," she says.
  
  The sprinklers release a loud noise and a burst of water, scaring the cat away."
• Motion-activated alarms. Humans can't hear the high-pitched sounds on these alarms, but cats can, and Dr. Humm-Beatty notes that it can scare them away. They're activated by heat or motion, and sometimes they can release a sound and a squirt of non-toxic repellent.
• Digging deterrent. Plastic mats with flexible spikes, egg shells and chicken wire are among the digging deterrents that can keep cats out of gardens (and perhaps your yard if they're digging there).
• Fox urine granules or spray. Dr. Humm-Beatty reports that the scent of these products is scary to cats, who think it smells like a predator. You'll need to reapply them regularly for effectiveness.

Plants That Help Repel Cats

Many plants, including lavender, rosemary and rue, can serve as natural repellents to keep cats out of your yard-or at least away from parts of it. Dr. Humm-Beatty says that plans that help repel cats include:

• Lavender. This pretty, sweet-smelling flower can elevate the look of your garden and keep cats away, but Dr. Humm-Beatty says cats don't like the scent of lavender, so planting it can help repel stray cats from your yard.
• Rosemary. This plant can repel cats year-round because it's an evergreen.
• Citronella. Dr. Humm-Beatty warns that cats don't like the smell of this plant either.
• Geraniums. "Geraniums have both a smell that cats hate, and they have prickly leaves that cats do not like the feel of," she notes.
• Oregano. Oregano's strong scent can repel cats, though Dr. Humm-Beatty points out that the chemical compound carvacrol can cause respiratory discomfort in cats. Therefore it's not a safe way to keep cats out of your yard and you should avoid planting it.

How To Keep Cats Out of Flower Beds

There are several effective ways to keep cats out of flower beds, including strategic plant choices, motion-activated devices, and simple physical deterrents. Many gardeners find that a combination of methods works best.

"Plants like lavender, along with motion-activated sprinklers or alarms and digging deterrents such as eggshells, can all help discourage cats," says Dr. Hilary Humm-Beatty.

Light reflection can also be an effective deterrent. "Random light reflections can startle cats away from your garden," Dr. Humm-Beatty notes.

However, if you're wondering: What is the best homemade cat repellent? Dr. Humm-Beatty recommends stringing together some old CDs and hanging them in your garden-the light may be just what it takes to keep your cat away from your flowers and homegrown produce. As a result, you may keep the cat out of your yard.

Gardeners typically use these methods to prevent cats from using flower beds as litter areas or damaging plants while digging.

Do Coffee Grounds Keep Cats Away?

Dr. Humm-Beatty says the strong, bitter scent of coffee grounds and beans that give you a morning jolt can repel cats from your garden and yard.

"Some gardeners grow coffee plants, and other gardeners scatter coffee grounds throughout their garden to repel cats," Dr. Humm-Beatty notes. "Coffee grounds also act as a fertilizer."

However, caution is important when using this method as coffee contains caffeine, which is toxic to cats if ingested. Because of this, if you're looking for a safe way to keep cats away without hurting them, don't go with this method.

What Not To Do To Keep Cats Away

Dr. Humm-Beatty understands that free-roaming cats can be a nuisance, but many municipalities protect them from cruelty. "It's important to choose safe, humane ways of deterring them," Dr. Humm-Beatty says.

While free-roaming cats can be a nuisance in gardens and yards, it's important to avoid methods that may cause harm or unnecessary stress. In many areas, cats are also protected under local animal welfare laws, making humane deterrence the safest and most responsible approach.

As a result, Dr. Humm-Beatty says it's important not to:

• Have poison chemicals in your garden as they can harm cats, other wildlife and children.
• Use harsh chemicals like bleach, ammonia or mothballs. Why? The scent of the chemicals may repel cats, but Dr. Humm-Beatty warns they can cause "respiratory harm to the cats and hurt other wildlife or children" who enter your yard.
• Spray anything-including water-directly at a cat. "This is traumatic for cats," she states.
• Use dangerous traps to keep cats out of your garden. Dr. Humm-Beatty advises using humane traps to catch feral or stray cats to avoid injury to the cats or wildlife.
• Use irritants that cause pain. Examples include cayenne pepper and chili flakes, which Dr. Humm-Beatty says can cause skin, eye or mucous membrane irritation.

When Outdoor Cats Become a Bigger Problem

Sometimes, plants and motion-activated sprinklers aren't enough to keep outdoor cats out of your yard. When that happens, it helps to understand what kind of situation you're dealing with.

Dr. Humm-Beatty says the first step is identifying whether you're seeing a small number of individual cats or a larger, established group.

"Stray cats might be cats that actually have owners in the neighborhood or may be cats that have been lost from their owners and are unhoused," Dr. Humm-Beatty notes. "Community or feral cats are cats that are part of a wild cat group that is roaming a predictable territory."

If the cat stopping by to smell your flowers has a collar or you know they belong to a neighbor, your best bet is to contact the owner to discuss the issue. If that doesn't work, Dr. Humm-Beatty says you should consider calling animal control.

When dealing with a larger group of cats, Dr. Humm-Beatty notes that long-term solutions require more than simply removing animals from a yard. Without addressing the underlying territory, new cats may eventually move in-a pattern sometimes referred to as the "vacuum effect."

"If you are dealing with a large group of cats, simply removing cats from your yard-or the nearby territory-is not a long-term solution," she says.

In these situations, it may help to identify whether a local group or community is already providing food or care. If so, connecting with local Trap-Neuter-Return (TNR) programs through animal shelters or humane societies can be a more sustainable approach.
