Is there any connection about my kitten throwing up in proximity near
the litter box?  Few days ago I saw a few dry food pellets with liquid
threw up just outside of the litter box.  Today I saw the exact same
thing in the exact same spot.    The pellets are just barely wet and
still in full shape.

Do kittens swallow the dry food without chewing?  I am feeding nutro
kitten food which is olive shape instead of the usual cross-like
shapes.

Sometimes he will immediately go use the litter box after eating, maybe
the smell from the litter box invoke him to throw up?  I scoop once a
day and just replaced all 100% of the litter after the first incident
(thought maybe it was smelly), today it happened again still.

I also free feed and he is always eating, in the middle of playing or
petting he would stop and go eat.   Would it help to raise the dish off
the floor so he doesn't have to tilt his head up from the dish and end
up swallowing some of the food without chewing?
