Cat is in good health. Birman female. Lives with another Birman same age, female. Has used litter box for 14 years. Litter box is cleaned and deodorized daily. Using Swheat Scoop & have for years. Cat has started using the carpet about 6-7 feet away from the 2 litter boxes in the room. No urine outside box yet that we have discovered. Nothing "different" has happened in the house. I shampooed the carpet 2 days ago but the problem began before that. Cat has run of the house - large rancher with lower level clubroom. This has been going on on an occasional basis for about 2 weeks but the last 2 days has increased. Any help/suggestions would be really appreciated. We love the cat but this behavior is totally unacceptable. The cats were my idea 14 years ago and my wife said OK but they are "your cats". She is not a happy camper. Years ago we had 3 litter boxes - have read "..you should have 1 more litter box than the # of cats". They never used it. The boxes are covered one. Help...............
