Bird beds are made of fleece and foam. They are soft, warm and cozy. Minnows measure 10" long, 7" wide and 10" high. Very roomy for your ferrets, hedgehog, rat, bearded dragon, guinea pig or other small pet. The bed is machine washable. Bird beds come with sewn on eyes. We have been making pet beds for some years. We have perfected the type of foam we use so the mouth stays open on its own. We do not use wire in the mouth to keep it open. The bed is soft for your pet, but the shell is firm to keep its shape.
