Why do dogs raise their paw when they go to the toilet, while cats don’t? - briefly
Dogs often raise their paw while urinating to mark their territory more effectively. This behavior allows them to leave a scent higher up, making it more noticeable to other dogs. Cats, on the other hand, typically squat to urinate and use scratching to mark their territory, relying more on visual and scent cues left on surfaces. The difference in behavior is rooted in their evolutionary histories and social structures. Dogs are pack animals and use urine marking as a form of communication within their group. Cats, being more solitary, use different methods to communicate and mark their territory. This includes scratching on vertical surfaces and using facial glands to leave scent marks.

Why do dogs raise their paw when they go to the toilet, while cats don’t? - in detail
The behavior of dogs raising their paw while urinating is a well-documented phenomenon that has intrigued animal behaviorists and pet owners alike. This action is primarily driven by the anatomy and physiology of the canine urinary system. When a male dog urinates, he typically lifts his leg to direct the urine stream onto a vertical surface. This behavior is instinctual and serves several purposes. Firstly, it allows the dog to mark his territory more effectively. By urinating on a vertical surface, the scent is deposited higher up, making it more noticeable to other dogs. Secondly, the act of lifting the leg helps to disperse the urine over a larger area, further enhancing the territorial marking.
The anatomy of the male dog's urinary tract is designed to facilitate this behavior. The penis of a male dog is equipped with a structure called the os penis, or bony penis, which provides rigidity during urination. This rigidity allows the dog to direct the urine stream with precision, making it easier to mark vertical surfaces. Additionally, the positioning of the urethral opening in male dogs is such that lifting the leg helps to avoid wetting the legs, which is a practical advantage in maintaining cleanliness.
In contrast, cats do not exhibit this behavior due to differences in their anatomy and social structures. Female cats, in particular, do not lift their legs while urinating. Their urinary tract is structured differently, with the urethral opening located closer to the body, making it impractical to lift the leg. Male cats, while they can lift their legs to some extent, do not typically do so for urination. Instead, they may use leg-lifting for marking territory with urine, but this is less common and more related to scent marking rather than actual urination.
The social structure and communication methods of cats also differ from those of dogs. Cats are generally more solitary animals and rely less on urine marking for territorial communication. They use a combination of scent marking with glands on their paws and face, as well as vocalizations and body language, to communicate with other cats. This reduced reliance on urine marking means that the behavior of lifting the leg is less prevalent in cats.
In summary, the behavior of dogs raising their paw while urinating is a result of their anatomical adaptations and social behaviors related to territorial marking. Cats, with their different anatomy and communication methods, do not exhibit this behavior to the same extent. Understanding these differences provides insight into the unique ways in which different species adapt to their environments and communicate with one another.
