Get your cat neutered. The fastest way to stop a male cat from spraying urine on doors is a quick trip to the vet. The majority of cats will not even start spraying urine if you have them neutered before they are six months old and their natural behavior kicks in.
Make your cats feel comfortable in their own home. Some urine spraying begins in multi-cat homes, where a cat might feel competitive or unsure of its position in the group. Give each cat a box to sleep in or a blanket to curl up on. If your cat has its own place to relax, it will be less likely to mark other places as belonging to it.
Keep your cat's routine consistent. Some cats get upset if their routine is changed and that can spark urine spraying. Moving its sleeping area, feeding it at a different time or even having a lot of visitors can upset a cat's sense of normality. Do not move things around in your cat's area unnecessarily, feed it at the same times each day and, if you have visitors, put your cat in another room away from the noise and upset.
Spray a pet repellent on any vertical surface your cat urinates on. Pet repellents, while inoffensive to humans, can smell terrible to a cat. Each time it sprays urine on a house door or other vertical surface, immediately clean the area with a damp cloth dipped in a pet-safe detergent and spray with pet repellent.
Introduce your cat to a new caregiver before you leave on a trip or vacation. Cats often think of their owner as a parent, so, when you are away for long periods of time, they become anxious. Let your cat meet the person who will take care of them a few days before you leave. This will relieve some of its anxiety, as the person will be familiar, and the change less likely to cause it to spray urine.
How to Keep Cats From Urinating on House Doors
Owning a cat that sprays urine on house doors and other vertical surfaces can be frustrating. Some owners think it is because their cat has poor hygiene habits, but it's not true. Cats spray urine around their home to mark their territory and warn other cats to stay away. House doors, particularly those outside, are a cat's favorite places to spray urine as they are potential points of entry by cats that do not belong to the family. Even though urine spraying is often a natural behavior in cats, you can keep your cat from doing it with a few simple steps.
