How To Convert Rabbit Years To Human Years

Rabbits are small mammals that come in many different breeds. They are popular pets and make great companions for children and adults alike. Rabbits have a very short lifespan, which can be confusing for those unfamiliar with their biology. Their age is determined by a combination of factors, including their breed and gender.

Rabbit is a non-ruminant micro-livestock with a unique digestive system that is able to digest fibrous materials better than other non-ruminants like chickens and pigs. You may be in dire need to convert rabbit years to human years; well, this article is for you. Not only does the conversion of rabbit years to human years is available here, but the article also goes further to explain expectations at different stages of a rabbit’s life.

What are Rabbit years to human years?

Rabbits have a life expectancy of 8 years, while humans can live up to 80 years. That means that, in human years, rabbits live 1/12th as long as humans. So if a human lives an average of 80 years, a 1-year-old rabbit would really be 6 years old.

However, veterinarians establish a correlation table (age chart) based on their observations of the rabbits’ ages, to see how these rabbits’ ages correspond to human age.

In order to convert rabbit years to human years, you need to know that rabbits have about a 10-year life expectancy. Humans have an average 75-year life expectancy, so 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.

The problem with this approach is that it fails to account for the different processes that are occurring in both species. Humans and rabbits both have gestation periods and lifespans, but humans have more complex brains than rabbits and therefore experience more complicated emotions during their development. This means that there will be more differences between how human babies grow up compared to how rabbit babies grow up than there will be between how each species grows old.

The difference between these two processes, pregnancy and aging, is what makes it difficult for us to convert one species’ lifespan into another’s without doing some math first: we need to account for those differences in order for our conversion formula to work correctly.

Lifespan of a Rabbit

Rabbits are some of the most popular pets and for good reason. They’re cute, they’re smart, and they live a long time.

Domestic rabbits can easily live to be 12 years old, and many can live for up to 15 years. This makes them an excellent choice for first-time pet owners who might not be ready for a commitment that lasts longer than the average life expectancy of a human (which is about 75 years).

There are several factors that contribute to the longevity of your rabbit, including diet, housing conditions, and genetics. If you’re thinking about adding a rabbit to your home, we hope this helps you make an informed decision.

Different Life Stages Of Rabbit


Newborn Rabbits

Did you know rabbits are born blind, deaf, and without hair? It’s true. During their infancy, baby rabbits are not uncommon to nurse from their mother rabbit for a few minutes throughout the day.

2-4 Weeks Old

The first signs that rabbits are able to be independent begin about two weeks after their birth. Most of the rabbits’ food will come from a mother’s milk. Rabbits generally are introduced to Alfalfa around the age of three weeks, but it is not recommended that they eat only Alfalfa hay; pellets are also recommended to ensure a healthy diet.

4-6 Weeks Old

The rabbits’ awareness will increase and they will begin to wean themselves from their mothers as well as drink and eat more Alfalfa Hay as they get older. Additionally, they will grow more hair on their bodies that serve as protective coverings and they will begin to grow up faster. Providing young rabbits with nutritional support that they cannot get from their mothers, Alfalfa Hay is important for their development. Usually, rabbits are not sold before six weeks of age. Upon reaching six weeks of age, rabbits should be fully self-sufficient and should be able to survive and mature separately from their mother. Knowing this information is essential for caring for your rabbit and providing a healthy environment for your animal.


3-6 Months Old

In general, male rabbits are considered sexually mature after 3 to 4 months old. Female rabbits at approximately 5 to 6 months old are also considered quite sexually mature. It is important during this time to have your rabbit spayed or neutered because male rabbits court female rabbits by spraying urine, while female rabbits tend to lunge and be very territorial. This will be greatly relieved with the spaying or neutering of your rabbit.  


6 Months-1 Year Old

When your rabbit is seven months old, you should begin to feed it Timothy Hay and to limit the amount of Alfalfa Hay you feed them. Timothy hay can provide your rabbit with vitamins and proteins that are essential to health and will reduce the chance of your rabbit gaining weight. The rabbit may be a little moody during this period as it becomes fully matured. This is essentially when they are trying to figure out where they belong in the animals around them, much like a teenager might find themselves feeling uncomfortable with a social group.

Young Adulthood

1-3 Years Old

It is very common for rabbits at this time in their life to spend much of their time exercising and roaming about the house. You must make sure to keep your bunny safe by rabbit-proofing your home.

Middle Age

3-5 Years Old

A rabbit becomes a little less active by the time he or she reaches this age. The scientific opinion is that rabbits become more affectionate at this age and they will trust you more.

Late Middle Age

5-7 Years Old

At this age in the rabbit’s life, it is extremely common that you might hear your rabbit complaining about their ability to stay clean. Make sure you consult the veterinarian from time to time to ensure you have done everything you can to keep your rabbit and its loved ones healthy and happy.

Old Age (How Long Do Bunnies Live?)

7 Years Old And Above

It’s not uncommon for your rabbit to calm down quite a bit even though some bunnies tend to be very active at this stage. At this point, rabbits tend to trust their owners and enjoy spending time with them. When rabbits get older, they need more time between them and people, so be sure to keep up with preparation and make sure that your rabbit is being well taken care of in order to help it stay as healthy and happy as possible. 

How old are rabbits when they are fully grown?

Rabbits grow quickly. It’s tempting to think of them as small, cute babies that will stay that way forever, but they grow up fast.

Rabbits are born with their eyes open and are weaned by 4 weeks of age. At 6 weeks old, they begin to eat solid food and should be separated from their mothers by the time they reach 12 weeks old.

Rabbits are sexually mature at 6 months old. Rabbits are generally considered fully grown at 12 months, depending on their breed. However, this is a general age range that can be affected by the breed of rabbit. For example, a dwarf rabbit is fully grown at 12 months old, whereas a giant rabbit may not become fully grown until it is five years old.

At what age do rabbits stop growing?

Rabbits can be divided into three categories based on size: small, medium, and large. The age at which a rabbit stops growing varies depending on the breed.

Smaller rabbits may not stop growing until they are 4-5 months old, while medium-sized rabbits may not stop growing until they are around 6 and 10 months. Large breeds may not stop growing until they’re 18 months.

Rabbits can live for up to 10 years if properly cared for, so knowing how long your rabbit will be growing is important to figure out when buying supplies and toys for your new pet.

Final Thoughts

Rabbits are very fast-growing animals, so they tend to live shorter lives than humans. In order to compare the two, you need to convert the rabbit’s age into human years. It’s important to note that there are many different factors that go into determining the age of a rabbit, including breed and gender.

However, we have discussed how to calculate the age of a rabbit based on its size and life expectancy. A rabbit’s lifespan depends on many factors including its care, diet, and environment. Rabbits kept indoors tend to live longer than those kept outside because they are protected from predators and have access to clean water at all times.

  1. I personally don’t agree with their chart and their math does not add up. As they say, if a rabbit is one year at one week than at two years the rabbit would be over 100!!? But they say that at 2 years a rabbit is only 27 years? So in conclusion these people either:
    1. Do not know how to do math
    2. say that certain years are longer than others.
    either way I am going to use the scale
    1 year=10 rabbit years

  2. My bunny rabbit is 11 years old and she looks in great health condition to live longer
    We had another 2 bunny rabbits, one lived 3 years and the other one 9 years ❤
    Wow my bunny is now 110 years old in rabbit age in your last counting comment !!!

    • My bun Barry is 11 and a half, in the last few days he’s sleeping most of the day and not moving much, he’s very very calm with his 10 year old buddy Ernie by his side. Having had over 15 rspca rescue bunnies over the years. I know my old boy is going soon in comfort and peace. Since his rescue, quality food, very best Timothy hay, stuffed into toilet rolls for variety, and quality human grade kale , spring greens, parsley etc. good food hay and good hygiene really does increase longevity in bunnies,and love. most pets too.
      Bunnies are not at all cheap to keep but spend the money and they will give you love for over a decade ( unless there’s a genetic reason why they pass on too soon, and many do sadly) even with the best care. I love buns. God bless them all and their good humans parents too

      • Your post moved me. I have lived with, loved, and lost several rabbits in my adult life. Everything you said is true, especially about providing a rabbit high-quality food, housing (not a cage, not in a backyard!!), health care and much love. They are unique animals – when you have gained a rabbit’s trust, it is a special thing, an uncommon bond. I have a twelve year old girl, Frenchie, who has recently gone completely blind, is having mobility issues, but we try to make her as comfortable as we can, and she has her good friend/partner Tuck to support her and comfort her. They are special animals. Thank you and all other good bunny stewards who make a rabbit’s life a better one.

  3. My boy is 13 and this chart seems accurate looking back. He was doing great up until last week. Suspecting kidney failure from old age. Diet, housing, and attention are keys to long lives for these guys so it can really depend on you how long they will live.
