Cats can eat tomatoes. Tomatoes contain lycopene and anthocyanins, which are beneficial for a cat's skin. Vitamins can also boost a cat's immunity, and dietary fiber aids digestion. Therefore, eating tomatoes in moderation is good for cats.

However, it is recommended to cut tomatoes into small pieces before feeding them to prevent cats from swallowing them whole, which could affect digestion and absorption, and even block the esophagus and affect breathing. When feeding a cat tomatoes for the first time, give it a small amount and observe for any abnormal reactions such as allergies, vomiting, or diarrhea.
