Marking, UI, and Urinating

The difference between a cat spraying or marking and eliminating fluid waste is based on the position of the body.

To spray or mark their territory, cats back up to the object, and remain standing to release the urine. They are also known to wiggle their tale while doing this.

Cats will squat very low to urinate, and they will then scratch and cover it up.

Cats with Urinary Infection will try to squat to urinate, but then will rise up as the urine leaves the body, since it is causing physical pain and discomfort.

Cats do not stand up to urinate, even with UI. If a cat is standing up while releasing urine, that is a marking behavior.
