Habitrail

Habitrail, a product made by the Hagen corporation, is a series of translucent plastic tubes and "houses" for use in home terrariums, designed specially for small pets, such as mice or hamsters. The design of the Habitrail is modular and can be configured however the owner likes, as well as disassembled for cleaning. The Habitrail is meant to mimic the habitat of the animal in question, usually a warren, or series of underground tunnels. The mascot for Habitrail is "Herbie the Hamster", who even has a video game based on him called Habitrail Hamster Ball produced by Data Design Interactive in 2005 and released for the PS2, and the PC.

Large Habitrails may contain multiple bathroom spots chosen by the pet, and a good Habitrail should incorporate small holes and metal bars to increase ventilation. Habitrails do not make good cages for gerbils, due to the tendency of these animals to chew obsessively.

Innovative features, including the bed, food area, and hamster wheel, make excellent use of the small areas. Use of clear plastics also makes it easy to see the hamster scuttling around the various pods and tunnels.
