Why Cats Use Plants as a Toilet & How to Stop It 2025 🌱

By Dr. Duncan Houston BVSc

If you’ve ever caught your cat digging in your houseplants—or worse, using them as a toilet—you’re not alone. While this behavior can be frustrating, it’s important to understand that cats aren’t being “naughty” on purpose. Instead, they are responding to their instincts, environment, or health needs. Let’s explore why this happens and how to prevent it.

🔹 Why Cats Use Plants as a Toilet

1. Litter Box Issues 🧹

Cats are very particular about their bathroom habits. If their litter box is:

• Dirty

• Too small

• In a noisy or high-traffic area

…they might look for a more appealing spot. The soft, loose soil in your plant pots can seem like an inviting alternative.

2. Behavioral or Medical Issues 🩺

Stress or illness can cause cats to change their bathroom habits. Common triggers include:

• Urinary tract infections (UTIs)

• Kidney or bladder issues

• Anxiety from changes in the household (new pets, moving, loud noises)

If your cat suddenly starts going in your plants, a vet visit may be necessary to rule out medical causes.

3. Preference for Soil 🌾

Some cats are naturally drawn to soil because it resembles the environment they would use in the wild. Unlike fine litter, the texture, smell, and feel of soil can be more appealing.

🔹 How to Stop Your Cat From Using Plants as a Toilet

1. Improve the Litter Box Situation ✅

• Keep the litter box clean by scooping daily and washing weekly.

• Ensure it’s large enough for your cat to move comfortably.

• Place it in a quiet, private location away from food and water bowls.

• Experiment with different types of litter—some cats prefer soil-like textures or unscented options.

2. Rule Out Health or Stress Issues 🩺

• Schedule a vet check-up to rule out urinary or digestive problems.

• Reduce stress by maintaining a consistent routine for feeding, play, and litter cleaning.

• Consider consulting a pet behaviorist if your cat’s stress is causing repeated accidents.

3. Make Plants Less Appealing 🚫

• Cover the soil with decorative rocks, pinecones, or aluminum foil—cats dislike stepping on these textures.

• Use a safe cat repellent spray on the soil.

• Create a physical barrier around plants, such as a small fence or mesh screen.

4. Provide Alternatives and Enrichment 🧩

• Offer a digging box with sand or soil-like litter that your cat is allowed to use.

• Use interactive toys, climbing posts, and scratching areas to redirect their energy.

• Rotate toys and provide cozy hideaways to keep your cat stimulated and satisfied.

🔹 Patience Is Key 🕰️

Changing this behavior may take time. Observe your cat, identify patterns, and adjust your approach gradually. Remember: punishing your cat is counterproductive and may increase stress, making the problem worse.

Bottom line: Cats aren’t being difficult—they’re following their instincts or responding to a need. By addressing litter box issues, checking for health problems, protecting your plants, and providing fun alternatives, you can help your cat break this habit while keeping your greenery safe.
