pooping outside litter box

Question
We have 2 4 month old male kittens that came from the same litter. When we first got them, it was no issue with potty training, but this last week 1 wasn't feeling well and spitting up.  It lasted only 1 day, but since then he's been pooping everywhere except the litter box.  I've discipline him by showing him what he's done then putting him into the litter box, but he still does it and only in the mornings.  What is his problem.

Answer
Sharon,

It may be a coincidence. It's possible the kitten has an intestinal problem like intestinal parasites, or an allergy to his food. If it is painful when the cat poops he will associate that pain with the litterbox and go elsewhere. You may want to take him to a vet for a checkup.

Also try putting another litterbox near where is he going that is bigger and with deeper litter. That sometimes will help.

It's possible that he sensed you were sick and was reacting to it. If so, then the pooping behavior should stop and he should get back to normal.

It's better to find out if his behavior is caused by a medical issue before dealing with it as a behavioral problem.
