The CritterTrail Triple Play Habitat by Kaytee is the perfect environment for your mice, dwarf hamsters, hamsters and gerbils. The 6mm wiring spaces keep your tiny pets safely inside of their home, and it is created in a way that allows you to re-configure the trails in three different ways. This stimulates and challenges your pets mind while keeping your pet entertained. The CritterTrail Triple Play Habitat can be attached to other habitats so that you can give your pet more space or create a different design. Included is a food bowl, water bottle and exercise wheel and has enhanced door locks with top and front wire doors.
