Eco-friendly inside and out, these cat mats are made with IntelliLoft® fabric created from recycled plastic soda bottles and 61% recycled batting that is carefully sewn inside to eliminate bunching. In addition to Eco Nap colors featuring a grey "bungee" underside, we are happy to once again offer three classic color combinations with a brown “bear” underside. One-piece machine washing and drying for easy maintenance. Non-toxic and Öko-Tex Standard 100 certified safe. Designed to fit standard-sized cat crates.
