Pet Behavior:
Inappropriate Urination

 

Lets take a look at inappropriate urination/defecation in the house by an animal otherwise trained to know where appropriate elimination is supposed to occur. There are medical reasons for both dogs and cats that must be considered when this happens, so be sure to rule these causes out by seeking veterinary attention.

Once behavior is determined to be the cause of the inappropriate elimination, then becomes the challenge of determining the cause of the inappropriate behavior, and attempt to correct it.

Cats will urinate/spray their urine onto objects in order to mark their territory.  This is a natural instinct, and one in which is normally observed in wild cats.  Domestic cats will be driven by hormonal and behavioral reasons to do the same.  Those who are sexually intact will do so at a higher frequency than those who are neutered or spayed.
Thus, the first recommendation is to have the pet spayed (if female) or neutered (if male) to curb the behavior.

Often times however, the cat has been spayed/neutered and will still urine mark their territory.  Usually these animals are driven by the instinct to define their territory, and especially so if threatened by another individual in the form of  a new cat, dog, or person entering their territory.  Keep in mind, that this individual does not necessarily have to live with the cat, but can be living outside the house and just be within view of the inside cat. 

Multi-cat households require adequate number of litter boxes (typically one box per 2 cats), and will require frequent cleaning.  Dirty litter pans, or competition at the litter pan, can drive a cat to urinate and defecate where he/she feels it is clean and safe.

Hormone therapy utilizing pheromones can also be tried as an alternative.
Finally, when all else fails, there are behavior modifying medications that can be utilized to discourage inappropriate urination/defecation behaviors in many affected individuals.  Although poorly understood as their mechanism of action, these drugs can be very useful, often times temporary, and most have minimal side effects.  Check with your veterinarian, or submit a post to Questions for the Vet for more information.

Dogs will also mark their territory especially the intact males.  These dogs definitely need to be neutered as a first line of treatment.  Otherwise, usually the dog remains well trained throughout most of his/her life, and if inappropriate elimination behavior occurs, have the dog checked for any medical concerns.
