My friend gave me some little rawhide bones as a gift for my hedgehog. She said that she found on the internet that they like them. I'm not sure about it so I thought I'd ask. The kind she bought are labeled as Petco brand Natural Rawhide For Dogs. They are about 2 and a half inches long with the knot sizes varying. Please let me know if I should return them or allow Herisson to play with them.
