How Old is Your Rabbit – In Human Years?

We’ve probably all seen the charts that give dogs a lifespan in “human” years. Its an easy way for us to relate how old our dog is compared to us. I’ve often wondered how old some of our rabbits are in human years. I thought it would be easy at first but ran into some complications.

I looked first at life expectancy for both people and rabbits. The general concencus for people is a life expectancy of about 75 years. Of course, there are many factors that contribute to thsi number, such as where on this planet you live. Finding acurate scientific answers regarding life expectancy of rabbits was a little difficult. So I averaged everything I found and came up with a life expectancy of 10 years.

The easy thing to do would be to divide the 75 year life expectancy of humans by the 10 years of life expectancy of a rabbit, and say that every one year of rabbit life would be equal to 7.5 years of human life. That looks all cute and everything until you say that a 6 month old rabbit which has reached sexual maturity is equal to a 4 year old human. Thats not going to work.

A rabbit reaches sexual maturity at about 6 months of age. People get to that point around 16 years of age (note: although they have reached sexual maturity, they typically are not yet mature in other ways). So that was my second age a 6 month old rabbits is equal to a 16 year old person. (My first was a 10 year old rabbit is equal to a 75 year old person.

The next step was to fill in the early years. Having both children and rabbits, I started to compare their behavior at various stages. Amazing how much behavior is paralled. After finishing the early years I then evenly spaced out the later years and came up with the following table:

Rabbit Age People Age
1 week 1 year
2 weeks 2 years
3 weeks 4 years
4 weeks 6 years
2 months 8 years
3 months 10 years
4 months 12 years
5 months 14 years
6 months 16 years
1 year 21 years
2 years 27 years
3 years 33 years
4 years 39 years
5 years 45 years
6 years 51 years
7 years 57 years
8 years 63 years
9 years 69 years
10 years 75 years

I think those that raise rabbits and have children could probably confirm that this chart is really not that far off. So next time someone asks how old your rabbit is in people years you can look at this chart and let them know!

    I think your chart is a bit off. At the age of 3 months rabbits can get pregnant and have litters, and like all teenage humans end up with some of the same complications. A ten year old female or male human is unlikely to be mature enough physically be able to even get pregnant, you might want to up the age to at least 13 or 14 and then increase the rest of the ages accordingly. My rabbit is 7 human years and is considered to be a retired senior in human years according to the vet!

  2. Thank you Cora. I ran this chart past many breeders who raise rabbits. They all agreed with the chart. Although I certainly respect the opinion of the vet, often they have not raised rabbits. It is possible for a 3 month old rabbit to have babies, but it is also possible for 11 and 12 year old humans to have them as well in some cases. It varies by individual rabbit and each individual person. The chart is a general guideline and not an exact rule.
