The South American degu, a small rodent, uses urine to mark its passageways. Its urine reflects ultraviolet light, which the degu can see.
Siberian chipmunks cover themselves in snake urine whenever they can to camouflage their own scent.
When two male hippos fight to protect their territory, they will turn so they are bottom to bottom. They then cover each other with a urine/excrement combination, while twirling their tails like propellers to spread it around. Hippos are retromingent, which means they are able to urinate backwards.a
