Mine like yogurt too. Others things are scrambled eggs, cottage cheese, sour cream, left overs of any kind, tomatoes, cucumbers, apples, cooked squash, watermelon, and canned peas and corn to name a few items.
My girls love watermelon! AND yogurt! I usually will mix things in the yogurt, like fruit or some of their feed. It doesn't take long to disappear! They also love apples, strawberries, corn on the cob and mealworms. Mealworms are by far their favorite!
