Tomatoes are a common staple in the kitchen. And while we don’t think of our feline friends being particularly interested in fruits, your cat might show some curiosity about that tomato in your salad or on your sandwich. But can cats eat tomatoes? Or are tomatoes toxic to cats? The answer is a little nuanced.
As a cat owner and gardener, you may wonder if it’s safe to have tomato plants around your curious feline friend. I examined this topic in detail to provide cat owners with a definitive answer on the potential risks of tomato plants for cats.
Overview of Tomato Plant Toxicity for Cats
The main concern with tomato plants and cats is that parts of the tomato plant contain a toxic substance called solanine. The stems, leaves, and unripe green tomatoes have the highest concentrations of solanine While ripe red tomatoes are safe for cats to eat, ingestion of the green parts of the plant can cause poisoning in cats if large quantities are consumed
When looking at the sources provided, the key facts indicate:
-
The green parts of tomato plants including stems, leaves, and unripe tomatoes contain solanine, which is toxic to cats. The ripe red tomatoes are safe.
-
Ingestion of solanine can cause symptoms like vomiting, diarrhea, lethargy, and difficulty breathing or seizures in severe cases.
-
Fatalities from tomato plant poisoning in cats are rare but veterinary care is recommended if ingestion occurs.
-
Preventing access to the plants through containment or cat-proofing is the best way to avoid potential poisoning
Signs of Tomato Plant Poisoning in Cats
If your cat ingests parts of a tomato plant, watch for the following symptoms:
-
Excessive drooling or foaming at the mouth
-
Vomiting and diarrhea
-
Lethargy, depression, or drowsiness
-
Loss of appetite or refusing food
-
Fast, racing heartbeat
-
Dilated pupils
-
Muscle tremors or seizures
-
Difficulty breathing
-
Death in severe cases with large ingestion
Contact your vet immediately if you see any of these symptoms after your cat was near tomato plants. Early treatment greatly improves the chances of recovery.
What Parts of Tomato Plants are Unsafe for Cats?
While ripe tomatoes are safe for cats, other parts of the tomato plant pose a risk:
-
Stems and vines
-
Leaves
-
Unripe green tomatoes
These all contain solanine and should be kept away from cats. Make sure your cat doesn’t have access to tomato plants in an outdoor garden. Trim any houseplants out of your cat’s reach.
Can Cats Safely Eat Tomatoes?
Red, ripe tomatoes are safe for cats to eat in moderation. Limit treats to just a bite or two of tomato as the acidity may cause stomach upset. Avoid feeding cats the green part around the stem, which may have a higher solanine concentration.
When giving tomato treats, provide only ripe red tomatoes. Remove stems and leaves. Cut or mash the tomato to make it easy to digest. Introduce new foods slowly to check for allergies or intolerance.
How Much Tomato Plant is Toxic to Cats?
The toxicity depends on the size of the cat, the amount ingested, and the cat’s sensitivity to solanine. Just a small nibble likely won’t cause any issues beyond possibly mild stomach upset. Large ingestions, such as eating several leaves or an entire green tomato, pose the highest risk for poisoning symptoms.
Kittens, older cats, and cats with existing health conditions have a higher chance of solanine poisoning. Seek prompt vet care even if you just suspect your cat ate part of a tomato plant. Don’t wait for symptoms if you know ingestion occurred.
Why Are Tomato Plants Toxic to Cats?
All parts of the tomato plant other than the ripe fruit contain a toxic glycoalkaloid compound called solanine. Found in plants in the nightshade family, solanine provides protection from insects and animals.
When ingested in large doses, solanine is toxic to cats as well as humans. It can interfere with nerve impulses and digestive function, leading to the symptoms associated with tomato plant poisoning.
Can Tomato Plant Poisoning be Fatal to Cats?
Fatal tomato plant poisoning is possible but quite rare in cats. With prompt vet care, most cats fully recover from solanine poisoning. The outlook is best when treatment begins quickly before severe symptoms develop.
Ingestion of a very large amount of tomato plant material could potentially be fatal. However, most cats taste the plant and spit it out when they experience the bitter, unpleasant flavor of solanine, limiting ingestion. Overall, deaths from tomato plant poisoning in cats are uncommon.
How to Prevent Cats from Eating Tomato Plants
Here are some tips to keep your cat safe from toxic tomato plants:
-
Grow tomato plants in raised garden beds or containers with trellises too high for cats to jump into.
-
Use hanging pots for tomato plants out of your cat’s reach.
-
Keep houseplants with seeds or leaves toxic to cats in rooms where your cat is not allowed.
-
Cover outdoor garden beds with plastic mesh or wire fencing to block access.
-
Use bitter apple spray on plants to deter chewing. Reapply frequently.
-
Provide plenty of safe, leafy greens like wheatgrass for your cat to munch.
-
Keep cats indoors to avoid exposure to neighborhood plants and gardens.
What to Do if Your Cat Eats a Tomato Plant
If you catch your cat nibbling on or near tomato plants, take these steps:
-
Remove your cat from the area to prevent further ingestion.
-
Check your cat’s mouth for any remaining plant matter.
-
Call your vet or an emergency vet clinic immediately for advice.
-
Closely watch for any symptoms of poisoning over the next several hours.
-
Follow your vet’s recommendation for treatment, which may include inducing vomiting and providing supportive care.
Take action right away if you know or suspect your cat ate any part of a tomato plant. Rapid response is key to preventing solanine poisoning.
Are Other Vegetables and Fruits Safe for Cats?
Many common garden veggies are toxic to cats, including:
-
Onions, garlic, leeks, chives
-
Avocado
-
Rhubarb
-
Potato leaves and green potatoes
-
Eggplant leaves
Some human foods that are safe for cats include:
-
Blueberries, strawberries, bananas
-
Cucumber, carrots, broccoli
-
Cooked sweet potatoes and yams
-
Watermelon, cantaloupe
Introduce new foods slowly and check for any signs of allergies. Always avoid plants and produce with known toxicity to cats when in doubt.
While tomato plants present a low risk of toxicity for cats, ingestion of the green parts of the plant could lead to solanine poisoning. Prevention is the best way to avoid this potential danger in your home and garden. If you believe your cat ate part of a tomato plant, immediate vet care is crucial. With prompt treatment guided by your vet, most cats fully recover from tomato plant poisoning.
What To Feed Your Cat Instead
Because they are obligate carnivores, the best “people foods” for your cat is lean, plain, well-cooked meat. Some go-to options include:
- Chicken
- Turkey
- Beef
- Salmon
- Tuna
Make sure the meat is thoroughly cooked and human grade, meaning there are no bones or scales. In small amounts, these are considered healthy snacks, and your kitty will likely thank you for them!
Remember that any treat you give your cat, including cooked meat, should make up no more than 10% of your cat’s daily calories. The other 90% should come from their well-balanced cat food. Always talk to your veterinarian before adding any new food to your cat’s food bowl.

Are Tomatoes Good for Cats?
Ripe tomatoes are not toxic to cats. However, cats are considered obligate carnivores, meaning that the bulk of their nutrition needs to be derived from animal meat products. As such, non-meat foods provide relatively little nutrition to cats.
So, even though tomatoes are packed full of vitamin C, folate, potassium, and vitamin K1, the amount your kitty would need to add any significant benefit to their diet is well above the amount their gastrointestinal tract is designed to handle. Therefore, while ripe tomato fruit is safe for cats, it’s also not recommended for them to eat.
