Also known as LAVA BLOX, these stones have been proven as a tooth conditioner for gnawing critters, including guinea pigs, hamsters, gerbils, prairie dogs, rabbits, and all small rodents.

At 1¾" square, they are made of pure volcanic lava and cut into squares.

They are safe from slivers and help keep teeth to normal size.

Highly recommended by Chinchilla breeders.
