Rabbit Age Calculator: Your Bunny’s Age in Human Years

Curious about how your fluffy bunny’s age compares to human years? Our Rabbit Age Calculator offers an estimation to help you better understand your rabbit’s current life stage and potential needs, especially as they hop into their senior years.

How Rabbit Aging Compares

Converting rabbit age to human years isn’t an exact science, as lifespan can vary significantly based on While rabbit aging isn’t an exact science, this general guideline helps estimate their life stages:

• First year ≈ 21 human years (rapid growth & maturity)
• Second year ≈ +10-15 human years (young adult)
• Each year after ≈ +6-8 human years (varies by breed & health)

*Smaller breeds (e.g., Netherland Dwarf, Holland Lop) often live longer (10-14 years), while giant breeds (e.g., Flemish Giant) may have shorter lifespans (5-8 years).*

Rabbit Life Stages and Senior Care

1. Baby/Kit (0-3 months)

• Rapid growth, dependent on mother’s milk.
• Begin weaning at ~4-6 weeks; introduce hay gradually.

2. Junior/Adolescent (3-6 months)

• Sexual maturity reached (spaying/neutering recommended).
• High energy; needs space to explore and chew-safe toys.

3. Adult (6 months – 5 years)

• Prime of life; stable diet (unlimited hay, fresh veggies, limited pellets).
• Regular vet checkups (especially dental health).

4. Senior (5+ years)

• May develop arthritis, dental issues, or decreased appetite.
• Softer bedding, easier food access, and more frequent vet visits.

As rabbits age, they might experience changes in mobility, dental health, or appetite. For more details on what to expect, read our article on understanding rabbit lifespans and recognizing signs of aging. Proper care, including a good diet and regular vet visits (with a rabbit-savvy vet), is crucial throughout their life. Reputable sources like the House Rabbit Society offer extensive care information.

Lifespan Factors

Several factors influence a rabbit’s lifespan, including:

• Breed: Smaller breeds often outlive larger ones.
• Diet: A high-fiber diet (mostly hay) is critical.
• Housing: Safe, clean, and stimulating environment.
• Healthcare: Spaying/neutering and regular vet checkups.
