This sounds like a behavior problem called marking. Some one is "claiming" that spot. Just to be sure, your first step is to get the cats to the vet just be sure there is no UTI.



You seem to be cleaning the spot with an enzyme cleaner which is good. Try putting foil over the spot and see what happens.



Check into using Feliway, a spray that mimics the happy scent cats leave when they rub their check against something. You can get it from your vet or from Cat Faeries at http://www.catfaeries.com or from the www.feliway.com site. Also check out Comfort Zone - a plug-in that difuses feliway. If you opt for Feliway spray, spritz it on the deodorized area and see if that helps.



Finally, if all else fails, ask your vet about using an antianxiety medication such as Buspar or Prozac. These very often work, however the decision to prescribe them will rest solely with your veterinarian who will be able to monitor the dosage and side effects. Since the marking doesn't seem to be all that severe, you might not need to go this far.



Good luck!
