RattyRat's Review: As chew toys, cholla chews fall short. Our rats had no interest in chewing on these really hard cactus pieces. However, these cholla pieces do work perfectly as an interactive treat toy. The pieces themselves have all sorts of holes in them and if you stuff all the holes with raisins and give it to your rat, they will have lots of fun digging the raisins back out of the holes.
