===Posture and Behaviour of the  Cat===

The posture of the cat can help in the differentiation process, since [[Indoor Marking - Cat|indoor urine spraying]] is usually associated with a [[Feline Communication Behaviour#Spray Marking|characteristic stance]]. This is related to the function of the marking behaviour since a standing posture allows the cat to deposit urine on a vertical surface at just the correct height for another cat to sniff at it and take in the important information.

When cats spray a location, they start by sniffing the spot (and often show a flehmen behaviour). The cat will then back up to the spot and spray urine with the tail erect. The cat often has a glazed look on its face, its tail with twitch and it will paddle with its back feet. This [[Feline Communication Behaviour#Spray Marking|characteristic stance]] is different from urination behaviour, even when cats urinate standing up. Urine marking does not exclusively occur from a standing posture and it can be performed from a squatting position, but with tail movements, and foot paddling that differentiate this form urination.  

However, urine marking does not exclusively occur from a standing posture and it can be performed from a squatting position, which closely resembles the posture adopted during the act of elimination. This fact must be borne in mind when attempting to differentiate between motivations as it is easy to dismiss squatting urination on horizontal surfaces as always being eliminative and yet there are occasions when the cat is actually using that sort of urination as a marking behaviour.

When cats urinate, they usually do not investigate the area by sniffing, and the tail movements and foot paddling are not seen. If cats with LUTD urinate standing up, they usually adopt an uncomfortable posture, strain as they urinate and may vocalise painfully.
