Cat not pooping in litter box

Question
Last month we adopted a 2 year old male cat from a local foster program. We have kept the food, litter, and type of litter box exactly as he was used to. He will pee in the box, but is only pooping outside on the deck or on the tile floor. The rescue group says this wasn't a problem before.  The Vet checked him out and couldn't find any physical problems.  How do we get him back into using the box?

Answer
Marc,

There could be many reasons and sometimes you need to try different things to figure out what that reason is.

Try getting a larger litterbox and put the litter deeper. Try moving the litterbox because he may not like the location or feel he has enough privacy. Try a 2nd litterbox.
