Catster reports that there are roughly 60 to 100 million unowned cats in the United States, including feral, lost, and abandoned cats. Unlike house pets, these cats have been lost or abandoned and have survived by forming colonies.
Stray cats can be adorable. However, when they start digging up your flowerbeds and commandeering your outdoor oasis, it might be time to show them the door gently! Dealing with stray cats can be a challenging and puzzling experience. But it doesn’t have to be a Tom-and-Jerry experience. These tips will help you cultivate a harmonious environment without ruffling furry feathers.
Plant Deterrents

One of the simplest ways to deter stray cats is to incorporate specific plants into your garden that naturally repel them. Plants such as lavender, rue, and rosemary are known for their intense scents, which cats typically avoid.
The American Society for the Prevention of Cruelty to Animals (ASPCA) cautions that lavender plants are toxic for cats (as well as dogs and horses). Additionally, the “Scaredy Cat” plant, a member of the mint family, emits an odor that cats find unpleasant. Consider designing your garden layout with these plants around the edges or in areas you’d prefer to be cat-free.
Coffee Grounds and Citrus

Citrus and coffee grounds scream, “Keep out, kitty!” According to Dr. Grace Gagnon, a renowned veterinarian and author of Feline Behavior Explained, “Citrus fruits contain acidity and an essential oil called limonene, which is harmless but highly off-putting to cats.”
Likewise, the earthy, bitter tones in coffee grounds disrupt a cat’s scent map, leading them to retreat in search of less odorous pastures. Garden enthusiast and Instagram influencer @GreenThumbGal shares, “After scattering coffee grounds, not only did my hydrangeas bloom, but my garden’s become a no-cat zone!”
House Digest cautions, “When you do, be sure there are no concentrated spots of coffee grounds, as caffeine in any form is toxic to cats if ingested.”
Motion-Activated Sprinklers

Their secret weapon? A sudden burst of water. Motion-activated sprinklers detect movement in your yard thanks to their infrared sensors. When a cat triggers the sensor, a quick burst of water is released, startling but not harming the animal. These gadgets are not limited to cats; they can deter other minor nuisances like rabbits and squirrels.
Cat Tales states that motion-activated sprinklers are one of the most effective deterrents when dealing with stray (neighborhood) cats. The bonus feature? These devices are eco-friendly and programmed to conserve water, using the water only when necessary.
Ultrasonic Devices

Ultrasonic devices emit high-frequency sounds that are typically inaudible to human ears but quite unsettling for felines. When a cat enters the device’s range, it triggers this sound, causing them to scamper off, leaving your sunflowers and lemongrass safe and sound.
Researchers from Murdoch University discovered that ultrasonic deterrents reduced the frequency of resident cats’ incursions into gardens by 46% and the incursions by 78%.
Devices like the YardGard and CATWatch have become favorites in the market. Each is designed to cover substantial outdoor areas with varying ranges and coverage.
Removing Food and Water Sources

Cats are curious and opportunistic. Their sharp senses easily pick up the scent of food, leading them to your doorstep. According to the American Society for the Prevention of Cruelty to Animals (ASPCA), minimizing access to food is crucial in reducing stray cat visits.
Securing potential food and water sources is crucial in mitigating stray cat activity. No food means no reason for repeat visits. Use locks or bungee cords on your trash bins to prevent stray cats from scavenging for leftovers.
Experts at The Humane Society suggest investing in animal-proof lids for the best results. If you feed pets outside, promptly remove any uneaten food. If you’ve got bird baths or water features, consider moving them indoors or surrounding them with a natural barrier.
Covering Sandboxes and Outdoor Furniture

Stray cats are wildly attracted to sand and soft soil for their digging and toileting habits. Covering these areas denies them the opportunity to dig in. Unprotected outdoor furniture is also prime real estate for sunbathing.
Taking measures further, slipcovers for patio furniture or outdoor cushions can also be a deterrent. Cats find tepid lounging spots irresistible; denying them access to your plush seating can reduce their visits. The Humane Society suggests using durable tarps or breathable covers, which can easily be removed when you’re ready to enjoy your outdoor space.
Using Physical Barriers

A report from the Humane Society states that strategically using fences, netting, or even thorny hedges can significantly reduce cat intrusion by creating inaccessible zones. Opt for materials like chicken wire or slatted garden borders, which can be an elegant fortification.
Another fabulous option is netting, especially for vegetable patches or flower beds. Experts suggest placing netting at a slight angle to prevent agile climbers from gaining a foothold.
Or explore modular plastic barriers, which are easy to customize and blend seamlessly with flower beds. Remember to bury fences a few inches underground to prevent sneaky diggers from entering.
Humane Trapping and Relocation

Humane traps, often readily available through local animal care organizations, are set up in areas where stray cats frequent. These traps are designed to catch the cats without injury gently. Once caught, the cats can be transferred to shelters or designated areas where they’re cared for, fed, and hopefully placed into new homes.
According to the Best Friends Animal Society, this method aligns with the trap-neuter-return (TNR) strategies that reduce cat populations by approximately 30% over a few years. Do not place more than one cat in a trap.
Building Shelters

According to the ASPCA, small, insulated shelters allow cats to stay warm and dry, reducing their need to seek refuge in less desirable spots, like under your porch or in your flower beds.
Studies indicate that cats are less likely to roam into human-inhabited spaces when shelters are strategically placed alongside feeding areas. Use materials like storage bins or wood, ensuring the structure is weatherproofed with straw for bedding.
A prominent cat caretaker community, Alley Cat Allies, highlights the importance of proper shelter placement and maintenance, particularly before the cooler months.
Creating a Cat-Friendly Garden

According to a study published in the “Journal of Feline Medicine and Surgery,” cats are drawn to loose soil, which they often seek for digging or bathroom purposes. Cover areas of exposed soil with decorative stones or pinecones—natural deterrents that can effortlessly beautify your garden while keeping cats at bay.
Densely planting shrubs or incorporating thorny plants can make your garden less appealing to cats, as they’re less likely to wander through cramped and prickly spaces. Cats appreciate sunlit napping spots, so strategically placing larger plants to create shade can discourage them from settling in.
