I had a female who would back up to a door and spray. We finally took that door out of our house and replaced it. She constantly had infections no matter what we did for her, which caused the spraying to begin. I also used some of the cleaners from Petsmart to neutralize the odor.
agree w/sadiemae...i had a prob w/one of my best behaved furries and took him to vet. turned out he had a bladder infection. she said when they have an infection, it hurts to urinate. so they don't use their box...it is like 'if i go in the box it hurts' so they go elsewhere...even though it still hurts for some reason they will keep it up...and not use thier box. my big guy never pooped...just wet...after antibiotics...have never had another problem. but you really should ck out at vets .... if not treated can cause permanent damage to kidneys etc. good luck.
