The Ocelot is mostly nocturnal and very territorial. It will fight fiercely, sometimes to the death, in territorial disputes. In addition, the cat marks its territory with urine. Like most felines, it is solitary, usually meeting only to mate. Ocelots hunt over a range of 18 km2 (6.9 sq mi), taking mostly small animals, including mammals, lizards, turtles, and frogs, crabs, birds, and fish. Almost all of the prey that the ocelot hunts is far smaller than itself, with rodents, rabbits, and opossums forming the largest part of the diet.
