Shape: L-shaped, designed to be placed in the corner of a cage, providing warmth from the bottom and sides, and allowing pets to snuggle via the perch. Temperature: Set to approximately 40°C, similar to a mother's body temperature, allowing pets to regulate their own body temperature. Safety: The cord is covered with a metal protective tube to prevent mischief. The temperature is low enough to prevent burns upon direct contact. Convenience: The perch is removable and can be used in 2 ways; attaching it sideways allows for warming from under a nest box. Maintenance: The surface has a clear coating that resists dirt and can be wiped clean with water for hygiene. Hardly used. Thank you for looking.
