For your hedgehog, guinea pig, or other small pet. They will love this cozy cuddly sleep snuggle sack. It is completely reversible just like all my other snuggle sacks. Approximately 9 x 10 inches uncuffed. Machine washable. Made from blizzard fleece and anti pill fleece fabric. A snuggle sack is a safe way for your little friend to stay warm in the winter and nice and cozy in the summer. Please note that there is a seam around the outside. Check after washes to be sure loose threads are out. Enjoy :) And please check out my other items.
