Guinea pig treats are mostly hay based sticks, chews for gnawing and small dried pieces of vegetable or fruit. A listing earns a place in your basket when it shows a plain ingredient line, a piece size that suits a small mouth and a pack size you will actually finish. Dried fruit, where it appears, comes in small pieces, so count them as you hand them out. Rabbits like many of the same shapes, and rabbit treats shows what is listed for them.
