The roomy 20″ basket is perfect for larger pets, up to 25 lbs, or a couple of average size cats/toy dogs or a whole litter of kittens or puppies. Cats will have as much fun playing with their toys in it as sleeping. Our photographers gorgeous 16 lb cat is pictured in the 20″ basket. In the videos, our 6 lb. kittens Shimi and Momo play with their toys in the 20″ basket.
