❓ Common questions

Can rats eat frozen blueberries?

Yes, frozen blueberries are safe and can be a fun treat. Thaw them slightly or serve them cold, but avoid giving large amounts at once to prevent stomach discomfort.

Limit treats to about 10% of their daily diet. For an average rat, 2-3 blueberries per day is a reasonable amount to prevent weight gain or diarrhea.

Are blueberry stems or leaves safe?
