House soiling in urinating, also called feline inappropriate elimination, is the most common cat complaint of cat owners.
When cats urinate on vertical surfaces, it is known as spraying. Usually the cat backs up to a vertical surface, raises its tail, which may quiver, treads with its anna winter escort feet, and directs a stream of urine backwards. Marking includes spraying urine on vertical locations; on occasion a cat may mark its territory by urinating small amounts on horizontal surfaces.
Rarely, if ever is stool used for marking. In this handout we will discuss the cat that is house soiling. For marking behavior, see Marking and Spraying House. Medical diseases of the urinary tract can cause inappropriate elimination.
There are many such conditions, including stones and crystal formation in the bladder, bacterial infections, and a group of inflammatory diseases of the bladder and urinary tract of suddenly origin that cause pain and an increased urgency to urinate. Diseases of the kidneys and liver can cause the cat to drink more and urinate more frequently.
In addition, age related cognitive brain function decline or endocrine disorders such as hyperthyroidism and diabetes might lead to changes in elimination habits including house soiling.
