What are the characteristics of a tiger's habits?

Tigers like to live a solitary life; only during the mating period and the nursing period do male and female tigers, or a mother tiger and her cubs, live together. Each tiger has its own territory, and when patrolling its territory it likes to mark the boundaries by urinating, scratching and rubbing tree trunks, defecating, and leaving tiger hair. Tigers have no fixed den and mostly roam through mountain forests in search of food; they lie low and rest during the day and come out to be active at night; they do not like hot weather, they can swim, and they are not good at climbing trees.

1. Tigers like to live a solitary life; only during the mating period and the nursing period do male and female tigers, or a mother tiger and her cubs, live together. Adult tigers, especially siblings from the same litter, are very likely to cooperate with one another for a period of time (whether it lasts long-term is unknown) and share their catch.

2. Each tiger has its own territory. When patrolling its territory, it raises its tail and sprays strongly scented secretions and urine onto tree trunks or into bushes; sometimes it also uses its sharp claws to scratch marks into tree trunks, or rolls on the ground to leave tiger hair, in order to define its sphere of influence. If there is an intruder, the male tiger usually follows a policy of killing it.

3. Tigers have no fixed den and mostly roam through mountain forests in search of food. They usually prey on large mammals, including various hoofed animals such as wild deer, wild sheep, wild cattle, wild boar, red deer, sambar, roe deer, musk deer, and muntjac. Sometimes they also catch various small animals, such as birds, monkeys, and fish. To aid digestion, they occasionally nibble on grass. When extremely hungry, they will also prey on domestic livestock, and even attack people.

4. Tigers generally rest during the day and come out to be active at night. They do not like hot weather, because they lack sweat glands; in summer they always look for shade under trees to hide, or soak and play in ponds, though their tree-climbing ability is far inferior to their swimming skills.
