Tigers are mostly solitary animals, except during mating and when females are with cubs. These large felines establish and secure their territories by marking boundaries with urine and feces. Once a territory is established, it will remain with that tiger until its death. There is little overlap of territorial boundaries between adults of the same sex. However, a male's territory may overlap the territories of several females.
Tigers can be tolerant of other tigers.
Examples are several tigers gathering together to consume a particularly large kill, a mother with her young and a male and female staying together while mating. Tigers communicate to one another by rubbing heads, roaring, purring and grunting. Avoidance, however, appears to be the rule rather than the exception. A habitat of dense vegetation, with scattered prey living alone or in small groups, favors a predator that hunts alone. On the Prowl Tigers depend less on smell and more on keen eyesight and acute hearing to ambush and capture prey.
