Why Do Cats Like to Eat Plants?

If you've ever caught your cat chewing on a houseplant or nibbling at the plants in your garden, you might find it amusing or sometimes worrisome. Most of us cat parents might find ourselves puzzled by their feline’s fascination with foliage. While a nibble here and there won’t hurt your cat, but if they ingest a good portion, it can cause them be to sick.

But why do cats like to eat plants in the first place and is it safe? And most importantly, how can you stop your cat from eating plants that may be harmful?

Let’s dive into this curious cat behavior and learn how to redirect the behavior safely.

Understanding Why Cats Eat Plants

While cats are obligate carnivores, meaning their diet is primarily meat-based, they sometimes chew on plants for a variety of reasons. The behavior is more common than you might think and isn’t always a cause for concern, unless of course the plant is toxic.

Below are the most common reasons why cats eat plants:

1. Instinctual Curiosity

Cats are naturally curious creatures. Plants offer an interesting texture, movement (especially dangling leaves), and scent that might pique a cat’s interest. For kittens, chewing on plants can be a way to explore their environment, similar to how human babies mouth objects.

2. Digestive Aid

Some experts believe cats may eat grass or plants to aid in digestion. Wild cats have been observed doing the same. The fibrous material could help them regurgitate hairballs or eliminate indigestible matter, especially if they're feeling a little off. It’s not that different from dogs eating grass.

3. Boredom or Lack of Stimulation

Indoor cats that lack enrichment or playtime might resort to plant-chewing simply out of boredom. Plants are often the most accessible “toys” available, especially if they hang over pots or swish when touched.

4. Nutrient Craving or Deficiency

Although it's less common, some cats may chew on plants due to a craving for certain nutrients, like fiber or folic acid. While most of the cat food sold today is nutritionally complete, cats with gastrointestinal issues or poor-quality diets might look for extra sources of roughage.

5. Stress and Anxiety

Some cats chew on plants or other non-food items as a form of stress relief. This is similar to compulsive behaviors like overgrooming. A new pet in the house, a recent move, or changes in routine can all trigger stress-related chewing. It’s not that different from when cats chewing on plastic.

Is It Safe for Cats to Eat Plants?

Not all plant nibbling is dangerous, but many common houseplants are toxic to cats. Even small amounts of certain plants, like lilies, pothos, or philodendrons can lead to symptoms ranging from drooling and vomiting to kidney failure. 

If you’re wondering, “Is it safe for cats to eat plants?” the answer depends entirely on the plant in question. Some non-toxic plants (like spider plants or cat grass) may be okay in moderation, but others should be kept far out of reach.

Warning Signs of Toxic Plant Ingestion in Cats:

If you see any of these symptoms, your cat might have ingested a toxic plant or simply too much of a save plant.

• Vomiting or diarrhea

• Excessive drooling

• Your cat is lethargic

• Loss of appetite

• Pawing at the mouth

• Tremors or seizures (in severe cases)

 If you notice any of these symptoms and suspect plant ingestion, call your vet immediately.

How to Stop Your Cat from Eating Houseplants

If you’re tired of finding your favorite fern chewed up, or worried about your cat’s safety, there are several steps you can take to discourage this behavior.

1. Make Plants Inaccessible

Move your plants to high shelves or use hanging planters that your cat can’t reach. For more persistent cats, a room or shelf with a closed door may be the safest bet.

2. Use Natural Deterrents

Cats dislike certain smells. Spraying diluted citrus (lemon or orange), vinegar, or pet-safe bitter sprays on plant leaves can help discourage chewing. Always test a small area of the plant first to make sure it won't get damaged.

3. Provide Safe Alternatives

If your cat is determined to chew, redirect that energy to cat-safe plants like cat grass (wheatgrass) or catnip. These are non-toxic and can satisfy your cat’s desire for greenery in a controlled, safe way. Or, if you are like me, get fake plants!

4. Increase Enrichment

A bored cat is more likely to turn to your houseplants. Offer puzzle feeders, interactive toys, or vertical spaces like cat trees and window perches. Spend time engaging in daily play sessions with feather wands or laser pointers to burn off extra energy.

5. Improve Your Cat’s Diet

If your cat’s chewing seems food-driven, speak to your veterinarian about your cat’s diet. A high-fiber or gastrointestinal-support formula might help reduce the urge to chew plants.

6. Train Your Cat with Gentle Correction

When you catch your cat in the act, gently redirect your cat with a toy or call your kitty away and reward your cat with a treat. Avoid shouting or punishment as it often increases anxiety and can worsen the problem.
