Male tigers use scent markings and vocalizations to attract females and establish dominance over rival males. Female tigers may mate with multiple males to ensure fertilization, with successful mating encounters resulting in copulation.

2. Gestation and Birth: After successful mating, female Bengal Tigers undergo a gestation period of approximately 100 to 110 days before giving birth to a litter of one to six cubs, although two to four cubs are more common. Births typically occur in secluded dens located in dense vegetation or rocky outcrops, providing protection and shelter for the vulnerable offspring.

3. Maternal Care: Female Bengal Tigers provide extensive maternal care to their cubs, nursing them with milk and grooming them regularly to maintain their hygiene and body temperature. Cubs are born blind, deaf, and entirely dependent on their mother for nourishment and protection, with the mother dedicating all her efforts to their care and survival during the early months of life.

4. Cub Development: Bengal Tiger cubs develop rapidly in their first few weeks of life, with their eyes opening at around two weeks of age and their mobility improving shortly thereafter. They begin to explore their surroundings and gradually transition to a diet of solid food, including regurgitated meat provided by their mother. Cubs stay with their mother for up to two years, learning essential hunting and survival skills before becoming independent.

5. Survival Challenges: Bengal Tiger cubs face numerous challenges to survival, including predation, disease, and competition from other predators. Mortality rates among tiger cubs are high, with many succumbing to natural threats during their first year of life.
