The exception is the lion. Cats are also very territorial, and keep a large home range. Usually, males have larger ranges that overlap several smaller females' ranges. This allows the male to have access to several females at once. Mating is usually a very violent affair, with screams and yelps coming from the female, and hissing and growling from the male.
All cats eat a mostly meat diet.
This ranges from mice and voles to deer. However, their diet is supplemented with grasses, and the unavoidable digested remains of grasses that remain in their prey's stomach. This provides them with nutrients as well as roughage to help keep their digestive system running efficiently. Cats range all over the world, everywhere except the poles. Most cat species are found in the tropic and subtropic areas.
