Habitrail® Cristal is a main habitat unit that serves as a safe and secure central living area for hamsters. Habitrail Cristal is completely compatible with all other Habitrail® items. The cage is constructed of plastic and wiring for both durability and excellent air circulation. A deep base design with rounded corners makes cleaning easy and minimizes mess. A large plastic door allows easy access to your pet and it has a lock to keep your pet securely inside. Two windows allow you to connect other Habitrail® items using our patented Lock Connectors (sold separately). Habitrail Cristal also includes a look out deck with ladder to satisfy your hamster’s natural need to explore and hide, a quiet exercise wheel, a chew-proof water bottle and holder with stainless steel tip, a food dish, and a litter guard.
