Indoor marking

Synonym(s): Indoor spraying

Contributor(s): David Appleby, Amy Pike, Meaghan Ropski

Introduction

  • Indoor urine marking may be performed by up to 12% of all cats, including about 10% of neutered males and 5% of spayed females.
  • Cause: normal behavior used to communicate in both sexes, commonly caused by increased emotional arousal (positive or negative) caused by territorial marking, anxiety or stress. Sites affected are of behavioral significance, eg points of entry and exit or are associated with the owner's scent.
  • Signs: deposition of urine and/or feces in the home or excessive scratching of items within the home.
  • Diagnosis: indoor marking involving urine and/or feces must be distinguished from inappropriate urination and/or inappropriate defecation Indoor toileting.
  • Indoor urine marking classically usually occurs from a standing position, the cat backs up to the vertical surface, the tail twitches, and a small amount of urine is deposited. Not all componens are necessarily present in every case.
  • Using feces as a marker (middening) involves purposeful deposition of feces in behaviorally significant locations.
  • Medically causes for urination and defecation outside of the litter box must be explored and ruled out.
  • Prognosis: marking, whether by urine, feces or scratching, is a normal cat behavior and prognosis is good if the inciting triggers can be identified and managed, and appropriate scratching surfaces are provided and used. If management cannot be achieved, may result in rehoming, relinquishment or euthanasia.

Pathogenesis

Etiology

  • Marking using urine, feces, or scratching is a normal behavior but when it is exhibited in the home it is often a response to environmental stresses (including visitors, home improvement or moving, new additions, whether human or animal), household cat conflict/aggresion, non-household cat conflict/aggression, a change to their routine or interactions with the owners, and punishment.
  • Indoor marking can occur in association with other anxiety-based behavioral conditions.
