Turtle Chasers Floating Treats made with Real Clam. The Taste Your Turtle Will Chase! Treats are supposed to be fun and interactive. Zilla Turtle Chasers float and encourage aquatic turtles to chase them around the habitat. Treat time becomes playtime and is fascinating to watch turtles hunt down and nibble off bits until the entire morsel is devoured. Made with clam, this treat is naturally attractive and nutritious too.
