How Long Does It Take To Train A Kitten To Use The Litter Box?

Question by sarah: How long does it take to train a kitten to use the litter box?

We have a cat & 1 kitten. We want her to know where the litter box is, but she hasn’t used it yet! It’s been about 10 days. She has learned how to walk on our leather couches without scratching them up, so I don’t think that this will be an issue for her =)
