Shelltech Small Animal Lava Bites, Hamster Chew Toys Chew Treats Teeth Grinding Block for Hamster Chinchilla (12 Pack - Flower)

This is not safe for chinchillas. Cleaning pumice stones tend to have a different texture, more like hard light weight sponge. It is best to stick with pet grade pumice stones. My chinchilla likes the pumice stones from Shelltech (sold on amazon). They have different shapes and some with predrilled holes for chinchilla toys. I don't like their ledges (they don't seem to screw on tightly on the cage walls). Here is the link: https://a.co/d/05YFwbSQ
