Of course you need another cat! But you don’t need to feed this one or clean up the kitty litter. But they'll still be your cat's new best friend. The 15″ diameter round interior is suited for average to smaller pets, up to 12 lbs.EASY CARE: The lanolin in the wool is anti-microbial and odor resistant which keeps your pet’s bed naturally clean. It can be spot cleaned with a sponge or vacuumed. If it becomes very soiled, you can wash it in the delicate cycle of a washing machine and air dry. Don’t put it in the dryer unless you have a hedgehog who might enjoy it.
