Rabbits race through childhood in a few months, then age at about six human years for every rabbit year.
| Rabbit age | Human years | Life stage |
|---|---|---|
| 1 year | 20 | Adult |
| 2 years | 26 | Adult |
| 3 years | 32 | Adult |
| 4 years | 38 | Adult |
| 5 years | 44 | Adult |
| 6 years | 50 | Senior |
| 7 years | 56 | Senior |
| 8 years | 62 | Senior |
| 9 years | 68 | Senior |
| 10 years | 74 | Senior |
| 11 years | 80 | Senior |
| 12 years | 86 | Senior |
| 13 years | 92 | Senior |
| 14 years | 98 | Senior |
| 15 years | 104 | Senior |
Rabbits mature remarkably fast, which is why the first year counts for so much:
| Rabbit age | Human years |
|---|---|
| 1 month | 3 |
| 2 months | 6 |
| 3 months | 9 |
| 4 months | 12 |
| 6 months | 14 |
By around four to six months most rabbits are like teenagers, which is also when many owners notice a change in behaviour.
Most pet rabbits live around 8 to 12 years, and some reach their mid-teens. Smaller breeds tend to live longer than large and giant breeds. A diet that's mostly hay, space to exercise and the company of another rabbit all help them live long, healthy lives.
There's no scientific formula for rabbit years, so treat this chart as a rough guide. It follows a commonly used rule of thumb: about 20 human years at one year old, then about 6 for each year after that.
About 20. A one-year-old rabbit is fully grown and roughly like a young adult.
About 44, roughly like someone in their forties. A rabbit this age is classed as adult.
About 62, roughly like someone in their sixties. A rabbit this age is classed as senior.
About 74, roughly like someone in their seventies. A rabbit this age is classed as senior.
About 86, roughly like someone in their eighties. A rabbit this age is classed as senior. Twelve is a good age for a rabbit, at the top end of the usual lifespan.
Figures follow a commonly published rule of thumb for rabbit ages and are a rough guide only. Life stages are approximate.
