How To Get A Better Kitten Bl2?

i was so lucky and i got a kitten from my friend. She is very cute, but she doesn’t know how to get rid of her litter box odor. I am not sure if it’s because i don’t let her out enough or what, but i need some help on this one! I have tried everything for a while now – the scents that come in little packets, different kinds of litter boxes with extra liners….nothing seems to work! Please help!!
