Rabbits grow extremely fast. Depending on the breed, it can take up to 12 months in order for a rabbit to be considered fully grown.
Small rabbit breeds can be considered fully grown at 5 – 7 months. While larger breeds such as flemish giants can take anywhere from 12 – 18 months to be considered fully grown.
When it comes to sexual maturity, depending on the breed, it can take anywhere from 4 – 7 months for a rabbit to reach sexual maturity or what they call the teenage years or rabbits.
Smaller rabbits would reach their sexual maturity faster at around 4 – 5 months while medium/large breeds would usually reach it at 6 – 7 months.
Now that I’ve given you the gist of the article, read on as I explain the article in more detail:
Rabbit growth timeline.
Rabbits grew fast during their first few months. Here’s what happens to your rabbit as they age:
Young rabbits(Birth – 12 months).
Baby Rabbits (birth – 3 months)
The first month is the most eventful when it comes to rabbits. Kits or baby rabbits are born with their ears and eyes closed and without any fur. At this stage(1-3 weeks), they are totally dependant on their mother to take care of them and to warm them.
Does or mother rabbits would only feed her kits twice a day quickly. So don’t be alarmed if it seems like the doe is not nursing her kits.
Just check the kits themselves by checking if their tummies are flat or round. Round meaning the kits have been fed.
At around the first week, kits would start to grow fur and their eyes and ears would soon follow to open at around day 10-12.
Then, at around three weeks, the rabbits would start to nibble on some solid food and are preparing to leave the nest.
Adolescence Rabbits (3 months – 6 months)
At 3-6 months, rabbits can live on their own. This is the age where most rabbits get adopted.
You may also notice some behavioral changes during this time as they reach their sexual maturity. Some behavioral changes could include spraying pee, being territorial, and aggressive behaviors.
That’s why it’s highly recommended that you get your rabbits neutered/spayed to prevent these unwanted behaviors. Neutering would also make it easier to litter train your rabbit.
Teenage Rabbits (6 months – 12 months)
For most breeds, depending on their size, teenage years(6-12 months) are where they would be ready to reproduce. This is also the time where most rabbit owners would neuter/spay their rabbits.
Adult rabbit(1 – 5 years) .
At 12 months, most rabbit breeds would already reach their maximum size. Some exceptions to this are giant breeds like the Flemish Giant where it could take up to 18 months to reach adulthood.
During this time, you should consider changing your rabbit’s diet to lower calcium contents to prevent renal diseases. Talk to your veterinarian for proper advice regarding your rabbit’s diet.
Adult rabbits also require regular exercise to manage weight. At least 4 hours of free running is recommended.
Senior rabbit(>6 years) .
Senior rabbits are rabbits that are more than 6 years old. Depending on your rabbit’s condition during this time, you may also need some dietary changes. Talk to your veterinarian.
How long does it take for a wild rabbit to mature?
Wild rabbits’ maturity age would vary depending on their breed. Small breeds would typically reach their fully grown age at 4-5 months. While medium breeds would reach their adult size at around 6-10 months.
Larger wild rabbit breeds can take up to 18 months to reach their adult size.
Here’s a table which shows the different wild rabbit breeds and their sexual maturity age as well as their fully grown age:
|Wild rabbit breeds||Sexual maturity age||Fully grown age|

No, rabbit breeds would mature depending on their size. Typically, smaller breeds would reach their maturity age faster at around 4-5 months.
While medium breeds would reach their maturity at 6-10 months. Larger breeds like Flemish giants can take up to 18 months to reach their full size.
