URS TERRARIUM - Small 30 x 30 x 30 cm. NEW! URS has just released a new range of Terrariums in four sizes that are suitable for keeping small reptiles, amphibians, insects and arachnids. The Terrariums are made from glass with sliding front doors. Each Terrarium comes with a large top-opening lid that locks securely in place. There are also spaces at the top for cords such as thermostat probe, light fitting cable or heating cord to pass through with the lid still securely in place. Each terrarium also comes with its own glass door lock to ensure the animal cannot be accessed by the unauthorised nor escape through easily opened doors.
