Can Cats Eat Tomatoes? (The Risks!)

No, cats shouldn’t eat tomatoes.

Tomatoes contain solanine, which can be poisonous to cats, dogs, and other creatures.

Solanium is present naturally in the tomatoes plant. It’s possible for solanine poisoning to occur when you eat green tomatoes or drink tomato juice; it’s also possible to ingest enough through your skin.

The solanine isn’t destroyed by cooking either, so always remove any tomato leaves, stems, vines, and green tomatoes from your yard to avoid accidental poisoning of cats.

What is solanium and how does it affect cats?

Solanum lycopersicum (tomato) and other plants in the Solanaceae family all contain solanine, a toxic alkaloid. 

In large enough quantities, solanine poisoning can cause drooling, vomiting, diarrhea, heart problems, dilated pupils, difficulty breathing or even death. Ingestion of just one to two green tomatoes can cause serious toxicity in some cats.

Can a cat die from eating tomatoes?

If they eat enough of them, then yes. Solanine poisoning is serious and can be fatal if not treated immediately.

How should I treat my cat if he eats a tomato?

If you catch your cat eating the plant, don’t panic. Call your veterinarian to discuss treatment options as solanine poisoning can require hospitalization for severe cases.

How do I prevent my cat from eating tomatoes?

It’s better to remove all access to plants at home and in your yard that are toxic to your cat.

Keep tomato plants out of reach or in an area that’s inaccessible to you and your cat, such as a high shelf or behind closed doors.

Do not allow your cat access to garden areas where tomatoes and other plants may be growing. If you suspect your cat has ingested solanium, contact your veterinarian immediately.

What should I feed my cat instead?

Feed your cat a high-quality commercial food formulated for cats.

Don’t feed table scraps to your cat unless they are from meat, fish, or poultry.

If you suspect that your cat has eaten any part of the tomato plant, bring them to the veterinarian immediately.

Can cats eat cherry tomatoes?

Yes, they do. Tomatoes that are green and unripe include stems and leaves of the plant, which contains solanine. Cherry tomatoes aren’t safe either, so remove them from your yard to avoid accidentally poisoning your cats.

Does tomato sauce also contain solanium?

Yes, tomato sauce contains solanium because it’s made from the whole tomatoes plant. Cats are usually not willing to eat enough of it for it to cause serious poisoning though.

Does tomato soup also contain solanium?

Yes, it does. Tomato soup contains solanium from the whole tomatoes plant just as tomato sauce does.

What about tomato paste?

Yes, it contains solanium from the whole tomatoes plant just as other forms of processed tomatoes do. So do not feed your cat tomato paste, soup, and sauce.
