RattyRat's Review: Our rats love these peanut bones and they are great for their teeth. These are high in protien though so don't give your rats too many too often. Many of the flavored bones work great for rats (although mine never liked the meat flavored), however if you are picking out a flavor bone in a pet store that is not this specific one, make sure the ingredients doesn't contain rawhide which is bad for rats.
