1. Mating: A male sabertooth tiger would mate with a female.
2. Fertilization: The male's sperm would fertilize the female's egg.
3. Pregnancy: The fertilized egg would implant in the female's uterus and develop into a fetus over a period of months.
4. Birth: After a gestation period, the female would give birth to one or more baby tigers called cubs.
While we don't have living sabertooth tigers to observe, we can study their fossils and compare them to modern big cats to understand how their reproductive process likely worked.
