My cat has for a couple years pooped outside the litter box, but lately in the last few months it has gotten worse.  He did have a urinary tract infection, but was treated and I have two litter boxes cleaned two times a day.  I am getting very frustrated!!!!  I have been in my new house for a year,, so their are not many changes in the last couple months. I do not understand this ongoing bx.

I will try moving the box, but I am not sure that will work.  Someone suggested outting him down, and I hate to do that. He has about four to five spots he will go in, and I am tired of treating the carpet. I feel like my house is starting to smell.  I am also going tot alk with the vet again.  ANY SUGGESTIONS??????????????
