Soft single-ply polar fleece fabric provides your pocket pet with a warm, cozy place to sleep without overheating. Roomy boxed corners allow for a more comfortable sleeping experience, much better than sleeping in a flat envelope like the pouches made by our competitors. Lightweight nylon webbing is used to securely and neatly attach the lobster-claw clasp to the pouch, without pulling or puckering the fleece fabric. Powder coated (anti-rust) metal lobster-claw clasp features a quick-trigger release tab and swivel D-ring base that makes it easy to attah and remove this pouch from the cage.
