It’s never pleasant to come home to find puddles of cat urine throughout the house. Why do cats feel the need to urinate outside of the litter box and what can be done about it? Firstly, you need to identify if your cat is spraying (also known as marking), as opposed to simply urinating inappropriately. When a cat sprays, he will usually urinate on a vertical surface (a wall, couch, door etc), with his tail erect, sometimes twitching his entire body, depositing a fairly small amount of foul smelling urine.
Why does a cat spray?
Unlike dogs, cats lack social skills, and spraying is a form of communication; their way of sending messages without actually having to confront one another.
How to stop the behaviour
Contrary to popular belief, not only male cats spray, females do it too, although generally not as frequently.
If you feel your cat is simply urinating inappropriately (and not spraying as outlined above), it is advised to consult your veterinarian as he could be suffering from a medical condition or other behavioural issues which only your veterinarian or animal behaviourist will be able to diagnose.
