<human>: Hey, I just got a kitten 5 days ago. He's very sweet with a friendly temperament, but we're having some issues with his litter box usage. Originally, we had one box on one side of the house (due to not many options of where we could put it) and it had crystal litter in it. He would use it to poop sometimes, and always pee in it. On the second day, he started pooping outside of it, and we thought he was simply confused. However, after he finished a meal, we put him in his box, and he ran out of it to go do his business on the opposite side of the house, where there is no litter box. 

We bought a second litter box and put it in the middle of the house, and filled it with the pellet-like litter, and changed the other box to clay litter. The same problem persists - he uses it sometimes, but now he's evolved to peeing outside of his box too.  We've decided the best course of action is to have him stay in the laundry room (where his box is, in a secluded area) so he will be forced to use his box and learn that's where he does his business. Of course whenever we want to play with him, we'll let him out, but until then he'll be staying in there as his "room" until it seems he's learned.  

Any advice at all would be appreciated, because I've had kittens previously and they had learned to use the box consistently within 1-2 days.

<bot>: Kitten uses box sometimes (mostly when we put him directly in it) and sometimes runs out of his box instantly to go do his business elsewhere
