They have a larger field of vision, but cannot see colours as well as people can. Behaviour Big cats must defend their home-range or 'territory' from others of their species. Smell is probably the most important form of communication and big cats spray urine and rub their scent on trees and bushes around their territory, as well as leaving scratch marks, to warn others to keep away. Society Tigers and leopards are solitary creatures, living and hunting on their own. When young, their mothers taught them all the skills they need to survive on their own.
Lions live together in groups called 'prides'.
The females hunt prey co-operatively, while the males defend the territory, their magnificent manes intimidating rivals. Reproduction After mating, the female tiger and leopard give birth and rear their cubs alone, while lions rear their young together in the pride. All young cats are helpless and rely on their mothers' milk. As they become weaned, they are dependent on the meat their mothers catch, before learning how to hunt for themselves. Big cat index .
