THIS IS MY TERRITORY
Aggressiveness between tigers depends on
how many tigers are in the area

safer for raising children

or take over their mothers territory

territory using scent and by scraping the tree

EVERYDAY LIVING
Tigers or mostly active at night this pattern
may change due to seasons or prey activity.
 Tigers constantly groom themselves to keep
their coats in tip top shape and to moisturize
using the oils that are given of by their glands.
 They spend most of their day in water
 They constantly patrol their territory

SCENT & VISUAL COMMUNICATION



Male and female tigers communicate through marking
territories
Define boundaries by using urine because of the smell
and sometimes feces
All tigers have a signature scent to mark territories, for
cubs to find their mother, and to identify each other.


This scent is located in the toes
Tigers communicate by using their tales. If the tail is
loosely hanging the tiger is relaxed; if the tail is moving
from side to side rapidly it is showing aggression
DID YOU KNOW…….

2 miles away
 Tigers purr only when they breathe out
while domestic cats purr when breathing
in or out
