Cat Peeing in same spot everyday

Question
Dear Melissa,

I have 4 cats in a 4 BR house.  We have 4 litter stations.  2 of the stations have the Fresh Step gravely type litter, the other 2 are corn based.  The cat with the peeing problem goes #2 in the corn litter boxes but he ONLY pees in the same spot, which is by the front door, on tiles, 2-4 times per day, everyday.  

Is there anything I can do to change this pattern?  

Thanks and happy holidays!

Answer
How long has this been going on? The first thing that should be ruled out is anything medically going on. Have you tried placing a litter box in that location and how large is the amount of urine as if they are small spots, that indicates an infection. Are all of the cats spayed/neutered and have you seen him urinate? I'm wondering if he's marking- is he standing up or squatting? When a cat is standing, it is marking.

Feel free to send me some more information so I can help you further.
