This playful bed is available in 1 size and 2 colors. The plush kitten sack-bed is a fun place to hide, peek or just take a nap. The sack makes the noise of a paper bag that all kitties love. The inside is lined with plush lambswool Sherpa. The outside is covered in poly/cotton for easy washing. Cats will play and be amused for hours and this will become one of the favorite hiding places.
