Why is my kitten suddenly pooping outside the litter box now?
There are a few things to consider; some cats will go in the corner of the litter box, so they end up hanging their tush over the edge and it goes out of the box. You could try a litter box with a cover or with high sides to see if that helps. The size of the box and ease of entry is something else to consider. If she is still small enough that she has to leap into something that she can't see into, getting in the box may be a bit daunting. Make sure the has an approachable entry for her.
Also consider if you changed the type or brand of cat litter. Some cats can be very picky. Go back to the old brand if you have switched. If you have not made a change it cat litter, you can also try a cat litter called Cat Attract-- its a brand of cat litter that most cats accept very well.
Another thing to keep in mind is other cats and the location of the boxes. If you have multiple cats, make sure that you have enough litter boxes. If you have 2 cats, have 3 boxes. If you have 4 cats, have 5 boxes. I know that seems like a lot, but its the best way to prevent negative cat interactions near a litter box, and avoid them feeling territorial. If you have an older cat, the box may have been "occupied" when she needed to go, or she may have been intimidated by the other cat being nearby and didn't want to get in a confrontation.
To be thorough, I would also recommend that you take her to your vet to see if there's any medical issue going on that could be contributing. Take a stool sample with you. If she has intestinal parasites or other causes of inflammation in her intestine, she could be having some urgency that doesn't allow her to quite get into the box. Also, if she is painful somewhere, she may be trying to avoid getting up into the box.
I hope that helps you. Thanks for asking Petco Pet Education Center, formerly Petcoach!
