There are lots of different treats available on the market for you to buy for you pets. Treats should only be fed in small amounts to prevent you rat from becoming overweight.

You always want to watch how much and how often you give rats certain treats. As, seeds are fatty for rats, and fresh produce can cause diarrhea. Yogurt, fresh or dried, can, also, affect a rat's stomach causeing diarrhea.

You can also make them treats. I would highly recommend buying a copy of the Scuttling Gormet by Alison Campbell as there are some great ideas in this book. You could also look at the Make 'n' Bake page on this website
