It’s not only a toy for kittens! My son LOVES to play in the boxes that his diapers come in. And when his little friends come over, they love to play in them too. You would think that a plain old cardboard box would get boring after a while, but my son finds a lot of ways to play with the box. It’s a place to sit, a stool, a hat and a place to put all his other non-toys.
