CritterTrail is a connectable & expandable system designed to grow with your pet

We suggest you start with a habitat that has everything you need to make your pet feel right at home. Each of our CritterTrail Habitats include a food dish, water bottle, and exercise wheel. All CritterTrail habitats are expandable and designed to connect to other CritterTrail habitats and fun-nel tube accessories, creating an unlimited amount of living space for your pet hamster, gerbil, or mouse.
