It looks like a piece of Obsidian from a nearby lava flow, but it’s Gnawt-a-Rock™! This durable throw toy is inspired by natural volcanic glass formed by rapidly cooling lava from Pacific Northwest volcanoes. Unlike Obsidian, the Gnawt-a-Rock is made with natural latex rubber, with a faceted, gum-massaging surface. Its irregular shape creates an erratic bounce, and it has a treat-dispensing design for interactive play and reward.
