Can Cats Eat Tomatoes?

Can cats eat tomatoes? While ripe red tomatoes are generally safe for cats in small amounts, they are not a recommended part of regular cat food. Green tomatoes, as well as the leaves and stems of the tomato plant, contain solanine, a substance toxic to cats. If your cat nibbles on a ripe tomato, it’s unlikely to cause harm, but green tomatoes or other parts of the plant can be dangerous. To ensure a safe cat diet, it’s best to stick to foods specifically made for cats and avoid letting them eat tomato plants or unripe fruits.

Are Tomatoes Good for Cats?

Ripe tomatoes are not toxic to cats, but as obligate carnivores, cats require most of their nutrition to come from animal based proteins. Non meat foods, like tomatoes, offer little nutritional value to them. Although tomatoes are rich in vitamin C, folate, potassium, and vitamin K1, the quantity a cat would need to consume to gain any real benefit far exceeds what their digestive system can handle. For this reason, while the ripe fruit of a tomato is safe for cats, it is not advisable to include it in their diet.

Can cats eat the tomato stems or leaves?

No, the leaves, stems, and unripe green tomatoes are not safe for cats to eat. So, are tomato plants toxic to cats? Yes, they are. These green parts of the plant contain solanine, a toxin harmful to cats. Tomatoes belong to the nightshade family, all of which contain similar toxic compounds.


If your cat has ingested any part of a tomato plant, including unripe tomato flesh, it’s crucial to contact a vet immediately.


Symptoms of tomato Poisoning In Cats include:


  • Reduced appetite.
  • Nausea, Vomiting.
  • Diarrhoea.
  • Drowsiness or confusion.
  • Tremors.
  • Dilated pupils.
  • Behavioral changes.

While ripe, red tomatoes are safe for cats in small amounts, green, unripe tomatoes are toxic. Always consult a veterinarian promptly if your cat eats something harmful. Consider comparing pet insurance plans to ensure you’re prepared for unexpected veterinary costs.

Are tomatoes bad for cats?

Are tomatoes bad for cats? Yes, especially before they are ripe. All green parts of the tomato plant, including unripe tomatoes, are dangerous for cats, which is why many pet owners choose to avoid feeding their cats tomatoes entirely as a precaution.


When considering whether cats and tomatoes are a safe combination, it’s essential to note that grocery store tomatoes may not always be fully ripe, even if they appear red. In North America, tomatoes are often picked green in Mexico or South America during winter and shipped unripe to maintain firmness. These tomatoes are later treated with ethylene gas, a natural chemical that helps them ripen artificially. However, this process can result in tomatoes that appear ripe but are still not safe for cats.


To ensure a tomato is genuinely ripe, it should be firm with minimal give when gently pressed. Always prioritize your cat’s safety and be cautious when it comes to feeding them tomatoes.

Do cats like tomatoes?

Do cats like tomatoes? It depends on the cat! Cats may eat tomatoes out of curiosity, but it’s unlikely to become their favorite snack. Their interest in tomatoes often stems more from curiosity than a genuine preference for the taste.


When it comes to cats and tomatoes, remember that tomatoes vary in size and flavor. Small cherry tomatoes are often sweeter, while larger heirloom varieties can be more tart or a mix of both. While some cats might seem to enjoy the taste of one type, they may not show the same interest in another. Ultimately, whether cats like tomatoes or not depends on the individual cat’s preferences.

Why are tomatoes included in the ingredients for cat food?

You might have noticed that tomatoes occasionally appear as an ingredient in cat food and wondered why, especially since unripe tomatoes can be harmful to cats. In many cases, pet food manufacturers add ingredients like tomatoes as fillers to bulk up the product. These fillers are often unnecessary, can lack real nutritional value, and may even take the place of more beneficial ingredients like real meat, fish, or Chicken.


Additionally, the inclusion of tomatoes in cat food might serve as a marketing strategy, designed to make the product seem healthier or more nutritious to cat owners compared to competing brands.

How much tomato can I give my cat?

If you suspect your cat has ingested any green parts of a tomato plant, including unripe tomato flesh, it’s essential to take them to a veterinarian or emergency clinic immediately. Even if you haven’t witnessed your cat eating the plant, watch for signs of tomato poisoning, which may include:


  • Reduced appetite.
  • Nausea, Vomiting.
  • Diarrhoea.
  • Lethargy or confusion.
  • Tremors.
  • Dilated pupils.
  • Behavioral changes.
  • Excessive drooling.

Do tomatoes have any health benefits for cats?

Can cats eat tomatoes? Ripe tomatoes can be safe for cats to eat in small amounts, as they contain some beneficial nutrients like vitamin C and other vitamins and minerals. However, cats are obligate carnivores, so they don’t need tomatoes or other human food as part of their diet. Tomatoes, especially unripe ones or green parts of the plant, can be harmful and cause symptoms like nausea, Vomiting, or other digestive issues if a cat eats a large amount.


Tomato sauce, often containing spices and additives toxic to cats and dogs, should also be avoided. While tomatoes can contain fiber and hydration benefits, cats primarily need meat for their nutrition. If you find tomato based food in your pet’s diet, ensure it’s in moderation and free of harmful additives. Always prioritize your cat’s health by sticking to food specifically designed for their needs.

How to feed tomatoes to your cat?

Start by removing all parts of the plant except the tomato itself, including the stems and leaves, as these are unsafe for cats. Make sure the tomato is fully red and ripe with no green or unripe parts.


Once you have a safe tomato, wash it thoroughly and slice off a few pieces. You can chop or dice the slices and even cook them to make them easier for your cat to eat and digest. If your cat enjoys the taste, you can offer it as a very occasional treat. However, tomatoes should never be a regular part of their diet. Always avoid giving your cat tomatoes seasoned with garlic, onion, or other harmful additives.

Can cats eat tomatoes seeds?

Can cats eat tomato seeds? Tomato seeds in ripe, red tomatoes are not toxic to cats and can generally be consumed in small amounts without causing harm. However, the seeds in unripe or green tomatoes can contain solanine, a compound that is toxic to cats. While a few seeds from a ripe tomato are unlikely to pose a problem, it’s best to remove them if you’re offering tomatoes to your cat, as they don’t provide any nutritional benefit and may be hard to digest.
