Yes, guinea pigs can eat fresh tomatoes in moderation. Only small portions should be offered as overfeeding can cause digestive upset. Guinea pigs can also safely eat the seeds and skins of tomatoes. Never feed tomato leaves or stems, as these are poisonous.
Benefits of Tomatoes for Guinea Pigs
- Safe in moderation — Small tomatoes, such as cherry, grape, and plum varieties, are suitable for guinea pigs. Larger tomatoes are also safe, but only a small chunk should be offered per guinea pig.
- Low sugar — Tomatoes are not very high in sugar compared to many other fruits.
- Juicy and tasty — Many guinea pigs enjoy the sweet, juicy flavour, making tomatoes a popular treat.
