Rabbit Age Calculator (Human Years)

Rabbit Lifespan

Domestic rabbits live significantly longer than wild rabbits (2–3 years). Small breeds (Netherlandshire Dwarf, Mini Rex): typically 10–12 years, occasionally up to 15. Medium breeds (Dutch, Rex): 8–12 years. Large or giant breeds (Flemish Giant, French Lop): 5–8 years. The oldest verified rabbit lived to 18 years. Indoor rabbits consistently live longer than outdoor rabbits due to protection from predators, temperature extremes, and better health monitoring.

Life Stages and Care

Baby or juvenile (0–6 months): rapid growth, high energy, need hay with leafy greens introduced gradually. Young adult (6 months–3 years): peak health, maintain healthy weight, spay or neuter recommended (reduces cancer risk by up to 80% in females). Mature adult (3–5 years): monitor weight, dental health checks important. Senior (5+ years): more prone to arthritis, GI stasis, and dental problems. Geriatric (8+ years for small breeds): regular vet checks every 6 months recommended.

Signs of Ageing in Rabbits

Early signs of ageing: reduced grooming (leading to coat changes), weight loss, decreased activity, and changes in litter box habits. Dental problems are extremely common in older rabbits — check regularly for drooling, reduced food intake, or preference for softer foods. Arthritis affects up to 80% of rabbits over 7 years — provide softer bedding and lower-sided litter trays. Annual vet checks should become bi-annual from age 5.

Diet Changes by Age

Under 7 months: unlimited hay plus gradual introduction of vegetables. Adults: unlimited timothy hay (80% of diet), 1 cup leafy greens per kg bodyweight daily, limited pellets (25g per kg). Seniors (5+): maintain hay, monitor weight, some seniors need more pellets if underweight. Never give: iceberg lettuce, avocado, chocolate, grapes, or raisins — these are toxic to rabbits.
