2014 AAFP/ISFM Guidelines for Diagnosing and Solving House-soiling Behavior in Cats

Caregivers of house-soiling cats frequently abandon or relinquish these pets to shelters where many are euthanized as unadoptable. Veterinarians can significantly decrease this number by preventing house-soiling or effectively treating it. To provide practice guidelines for veterinary professionals, the American Association of Feline Practitioners (AAFP) and the International Society of Feline Medicine (ISFM), have released the AAFP/ISFM Guidelines for Diagnosing and Solving House-Soiling Behavior in Cats, which has also been endorsed by the American Animal Hospital Association (AAHA).

The AAFP/ISFM Guidelines for Diagnosing and Solving House-Soiling Behavior in Cats contain scientifically documented information when available and provide practical insight that reflects the accumulated clinical experiences of the authors. The Guideline emphasizes that this unwanted behavior is not due to spite or anger toward the caregiver, but because the cat’s physical, social, or medical needs are not being met. The Guidelines replace the term “inappropriate urination” with the term “house-soiling” because “house-soiling” implies no misconduct by the cat and thus, may encourage caregivers to better follow veterinary recommendations.

These Guidelines help clinicians identify the causative factors of house-soiling and include a cat owner questionnaire which is customizable for practice use. Within the document is an algorithm for the diagnosis and treatment of the four basic categories of house-soiling. The Guidelines propose and explain two universal suggestions for the management of all cases of house-soiling: (1) optimizing the litter box/tray and (2) meeting the “five pillars” of feline environmental needs. They also include specific treatment suggestions for each diagnostic category, take-home instructions for cat caregivers, and what steps practitioners can take if the frustrated caregiver is considering euthanasia.

“Our hope is that by using these Guidelines, veterinary practices will be able to more effectively and confidently address cases of feline house-soiling,” says Hazel Carney, DVM, MS, DABVP, and AAFP Advisory Panel Co-chair. “Success with these cases will improve the veterinary-client-patient relationships and overall feline welfare while keeping cats in their homes with a good quality of life.”
