• A wild rabbit is born hairless, blind, and helpless, weighing 40–50 g. Its eyes open 10 days after birth.
• A wild rabbit lives up to 12–15 years. Maximum lifespan is rare, as most individuals do not live past three years.
• The doe seals the nest chamber after each visit and nurses the young only once a day.

European rabbits typically live for 5 to 9 years, with a maximum lifespan of 13 years, and a theoretical lifespan ranging from 9 years and 4 months to 10 years and 5 months; the age of sexual maturity varies from 3 months to 2 years. The young’s eyes open between 1 week and 1 week and 4 days. The "Embryo" stage involves the embryo developing within the mother's body for approximately one month, during which it does not feed independently. Following birth, the species enters the "Kitten" stage, where the newborn is naked, blind, and lives in a nest within a burrow, lasting from 1 day to 3 weeks. The "Adult" stage begins when the animal is capable of reproduction and living independently, and this stage lasts from 5 months to 8 years and 3 months.
