Crickets - Apparently, rats will eat these? I've never done it, I don't need crickets running around in my room. Good for protein
Dog biscuits - ratnutrition.com recommends 'Grreat Choice Healthy Treats'??
Hard-boiled eggs - I've heard these are good for pregnant rats who need the extra protein/fat. However, these should not become a regular part of the diet but rather just a treat for regular rats.
Popcorn - Unsalted and unbuttered
Yogurt drops - Rats love these. At least, mine do.
Yogurt - a small amount of probiotic yogurt is good for gut flora
