Urinating at places are usually made by cats who want to mark its territory, the sign of a confident cat. However, insecure cats make marks by urinating too, and it's a type of communication between felines. Urine-marking causes vary; sometimes it is to mark a territory, or to show aggressive behavior, a sexual calling, or even being frightened and unsure.

Spraying is what cats do, so don't worry if you think your cat is overdoing it. It is not a sign of bad behavior. Just because the cat does it does not mean that it is spiteful towards you as the owner, or other deliberate reason. Being an animal, this is the way they react towards particular situations, and do not be overtly worry if they are just doing what nature made them out to do.

However, cat spraying is not the same as urinating indiscriminately. You should know the difference as a cat owner. It could be that your pet is avoiding the litter box, whether if it is unclean, or because there are other cats in the household that intimidates it. Also, it could have a urinary tract infection. Peeing on places, usually with horizontal surfaces is not spraying; rather, it means that the cat has a problem.

That said, it is clear that cats usually spray onto vertical objects, which to them is a sign of communication, not just territorial behavior. A cat remains standing when it sprays, unlike the squat position when taking a leak. Before it sprays, it will go backward towards the area, and then its tail will quiver, front paws kneading into the ground. Then he will spray urine as high as possible onto the area it targeted.

Furthermore, cats may spray vertical areas as well instead of objects, for example, sofas, rugs or beds. To know if it is a problem with marking, check the urine, whether if it is in a spray or puddle. Sprays means that it is being normal and making its mark, and puddle means that your cat needs more training or a visit to the veterinarian. See below for more information on cats training.
