Can cats eat tomatoes?

Ripe red tomato flesh is not usually a major concern in a tiny plain taste, but tomatoes are still best treated cautiously. Unripe fruit and every green part of the plant contain solanine and should stay away from cats.

How much is okay?

Usually skip tomatoes. If you offer a taste of ripe red flesh, make it tiny and keep all green parts completely out of reach.

Kitten / small adult
None recommended
Kittens are better served cat-specific treats.
Typical adult
A pea-sized taste of ripe flesh
Plain red flesh only; not a routine snack.
Large / big appetite
Up to 1 small bite
Never green fruit, vine, leaf, or stem.

Rule of thumb: treats of all kinds should stay under ~10% of daily calories.

How to prepare them

  • Use only fully ripe red tomato flesh if offering any.
  • Remove all stems, leaves, vines, and green or unripe portions.
  • Serve plain—no sauce, salsa, pizza, salt, onion, garlic, or herbs.
  • Keep tomato houseplants and garden plants inaccessible.
  • Stop after a first small taste if your cat is not interested.

Risks & exceptions

  • Green tomato parts contain solanine, which is toxic to cats.
  • Tomato sauces commonly contain onion and garlic.
  • Acidity can cause stomach upset in sensitive cats.
  • Garden access creates repeat exposure risk from leaves and stems.

Treat green tomatoes and tomato plants as unsafe. Call for veterinary advice if your cat chewed leaves, stems, vines, or unripe fruit.

If they ate too many

A tiny taste of ripe flesh may only cause digestive upset. Plant or green-fruit exposure needs a more cautious response.

  • Drooling or lip licking
  • Vomiting
  • Diarrhea
  • Reduced appetite

Call your vet / pet poison line if:

  • Chewing tomato leaves, stems, or vines
  • Weakness or unusual sleepiness
  • Dilated pupils or confusion
  • Repeated vomiting or trouble breathing
