Tomatoes are not inherently dangerous to cats in small amounts, but there are important cautions to consider. Key points

• Ripe tomatoes: In small quantities, ripe red tomatoes are generally considered safe for many cats, but they offer little to no nutritional benefit for obligate carnivores and should not replace a balanced diet.

• Unripe parts and plant: The green, unripe parts of the tomato plant (including leaves and stems) contain solanine and other related compounds that can be toxic to cats. Ingesting even small amounts can cause digestive upset or more serious symptoms in sensitive animals.

• Tomato products and additives: Tomato sauces, soups, or canned tomatoes often contain salt, sugar, garlic, onions, and other ingredients that can be harmful to cats. These additives can pose additional risks beyond the tomato itself.

• Veterinary guidance: If a cat shows signs such as vomiting, diarrhea, drooling, lethargy, or signs of distress after exposure to tomato plants or tomato-containing products, contact a veterinarian promptly. Severe signs (e.g., depressed mood, dilated pupils, slowed heart rate) warrant urgent care.

Practical guidance

• If your cat tries a small nibble of a ripe tomato, monitor for any unusual symptoms and avoid offering tomato plants or unripe fruit.

• Keep tomato plants out of reach, especially in gardens or pots, to prevent access to leaves and stems.

• For treats, consider cat-safe options specifically designed for feline nutrition rather than fruits or plant material.
