You've got your basic Koko and All Ball.
But I kind of like it best when they're the same size.
Of course, if your cat is bigger than your monkey, things can get pretty wacky.
With 4 hands, you can hold your kitten and eat a banana at the same time!
How could I pass up a chimp and a white tiger.
Don't you wish you could curl up with a cat and a monkey and take a nap right now?
