Even your small pets like to play with toys.  Hamsters chew and chew often, so buy them something made of natural materials.  Not only will it last longer, but it will be safer for them also.   No paint pieces, no unsafe residue or chemicals to harm them.   The all natural Bark N Sisal Ball is made of wood with twine, perfect for grinding down teeth.
