Also, they eat various insects like mealworms, crickets, etc.
This means tomatoes are nowhere in their natural diet. But it doesn’t mean gerbils cannot have tomatoes; they can but in limited quantity.
But tomatoes are not the best choice for gerbils.
Domesticate gerbils, for example, should eat a high-quality gerbil mix, grains, and pellets. Fruits and vegetables should only be a small portion of their diet. It’s important to keep their diet balanced for complete nutrients.
Now you know what gerbils eat, let’s move to the main question.
Can I Feed Tomatoes To My Gerbils?

This means your gerbils should never ingest the leaves, stems, and green tomatoes.
Do Gerbils Enjoy Tomatoes?
