Dogs and cats are territorial animals. This means that they “stake out a claim” to a particular space, area or object. They let other people and animals know about their claim by marking it with a variety of methods and at many levels of intensity. For example, a dog may bark to drive away what he perceives as intruders to his territory. A cat may mark a valued object by rubbing it with her face.
Some pets may go to the extreme of urinating or defecating to mark a particular area as their own. Urine-marking is not a house soiling problem, but is a territorial behavior. Therefore, to resolve the problem, you need to address the underlying reason for your pet’s need to mark his territory in this way.
