Can cats eat tomatoes?
CautionLast updated: 2026-06-09
Quick answer
Cats should avoid tomato plants and green tomatoes. Ripe tomato flesh is not a useful cat treat.
First checks before you decide what to do
Food safety depends on the exact ingredient, the amount eaten, your pet's size, and whether there are added sweeteners, spices, fat, bones, pits, skins, wrappers, or seasonings. Do not rely on the food name alone. Check the ingredient label and save the package if your pet already ate it.
If the food may be toxic, if you see repeated vomiting, breathing trouble, collapse, seizure, severe weakness, or unusual behavior, call a veterinarian, emergency animal hospital, or animal poison control service promptly.
