Urine Marking in Cats
Urine marks are usually deposited on vertical surfaces Marking on a vertical surface is known as spraying. Cats who live in houses might not have to hunt for their food or find a mate, but they still look at their world in the same way as cats who must survive on their own. They can only use the social and communication skills that nature gave them. If their world is predictable, there are no conflicts, they are spayed or neutered and they don’t need a mate, cats have little reason to mark and probably will not. But, if they want a mate or they are distressed about something, they’ll deal with their distress like any cat: they’ll mark their territory. To a cat, marking helps keep unwanted individuals away—whoever and whatever those individuals may be—and it creates an atmosphere of familiarity that makes them feel more secure.
