Standard Snooze Cubes have two inner layers of polar fleece plus a lining of polar fleece, and a fleece or cotton outer.
Hold 2/3 rats or 1/2 Chins. These quantities are a very loose guideline however, as many more have been known to pile in and squish up!
Size comparison with my other cubes:
Standard Snooze – 9l” x 6.5″h x 6.5″d
Luxury Snooze – 10″l x 8h” x 7.5″d
Luxury Hooj – 11.5″l x 7.5″h x 8.5″d
