Cats can eat tomatoes, but in moderation. Tomatoes are rich in lycopene and anthocyanins, which are beneficial for a cat's skin. Vitamins can boost a cat's immunity, while dietary fiber helps promote digestion. However, because tomatoes have a high water content, excessive consumption may cause diarrhea in cats.

Furthermore, cats' carnivorous nature means they have a weaker ability to digest plant fiber, and the nutrients they obtain from tomatoes are limited. Therefore, although cats can eat tomatoes in moderation, their daily diet should still primarily consist of cat food. When feeding tomatoes, it is recommended to cut them into small pieces to prevent cats from swallowing them whole, which could affect digestion and absorption or cause esophageal obstruction.
