Thinking outside the box: feline elimination

Feline elimination problems are the leading behavioral complaint of cat owners. When presented with a feline elimination problem there are three main diagnostic categories: medical problems, marking or toileting problems. It is important to first perform diagnostic tests to rule out and/or address underlying medical issues and all feline house soiling patients should receive a comprehensive physical examination. When the elimination problem persists after a medical problem has either been ruled out or remedied, a behavioral diagnosis should be obtained. The primary distinction that must be made in a behavioral diagnosis is whether the cat is engaging in marking behavior or selecting a spot other than the litterbox for elimination (a toileting problem). The motivation for urine marking may be territorial behavior or anxiety/stress whereas toileting problems are often triggered by medical causes, aversions, preferences or anxiety. Marking animals should be neutered and additional treatment measures may include reducing conflict and stress in the environment. Drug therapy has been long used to help control urine marking and recent studies have furthered our knowledge about the most appropriate treatments. Treatment for toileting problems should focus on providing an attractive litterbox while reducing the attractiveness or accessibility of inappropriate target spots.
