Raising bunnies can be an extremely rewarding experience, especially watching your new furry friends grow up before your eyes. If you’re a first-time bunny owner, you may be wondering just how quickly these adorable pets grow from tiny newborns to fully mature adults.
If you’re short on time, here’s a quick answer to your question: Bunnies grow very quickly in their first few months, reaching full size by around 6-8 months old.
In this comprehensive guide, we’ll cover everything you need to know about the growth timeline of domestic rabbits from birth through adulthood. You’ll learn key facts about their rapid baby bunny stage, when they reach sexual maturity, and what to expect as they fully mature.
Newborn Stage: The First Weeks of Rapid Growth
When it comes to the growth of bunnies, the newborn stage is a crucial period of rapid development. During this time, baby bunnies go through significant changes as they adjust to their new environment and start to develop their physical and sensory capabilities.
Birth Weight and Size
At birth, baby bunnies, also known as kits, are incredibly small and fragile. On average, they weigh between 1 and 1.5 ounces (28 to 42 grams) and are about the size of a small mouse. However, their growth rate is remarkable, and they quickly start to gain weight and increase in size.
It is important to note that the birth weight and size of bunnies can vary depending on the breed and genetics. Some larger breeds, such as Flemish Giants, may have bigger kits compared to smaller breeds.
Milk Diet for Nursing Bunnies
During the newborn stage, baby bunnies rely entirely on their mother’s milk for nutrition. The mother rabbit produces a special kind of milk that is rich in nutrients and essential for the kits’ growth and development. This milk is higher in fat and protein compared to the milk of many other mammals.
The nursing period typically lasts for about 3-4 weeks, during which the kits nurse multiple times a day. As they grow, their appetite increases, and they consume more milk in each feeding session.
When Baby Bunnies Open Their Eyes
One of the exciting milestones during the first weeks of a bunny’s life is when they open their eyes. Baby bunnies are born with their eyes closed, and it takes about 10 to 14 days for them to open. The exact timing can vary, but once their eyes are open, they can start exploring their surroundings and interact with their littermates and mother more actively.
It is important to provide a safe and comfortable environment for the baby bunnies during this time, as their eyes are sensitive to light and they may need some time to adjust.

1-2 Months: Transitioning to Solid Foods
As bunnies reach the age of 1-2 months, they go through an important stage of transitioning from a diet primarily consisting of their mother’s milk to solid foods. This period is crucial for their growth and development, as it sets the foundation for their future nutritional needs.
Weaning and Introducing Solids
During this phase, bunnies are gradually weaned off their mother’s milk and introduced to solid foods. The process of weaning usually begins around 3-4 weeks of age, with a gradual reduction in the amount of milk they receive. This allows their digestive system to adapt to the new diet.
Introducing solid foods to bunnies at this stage is important to provide them with the necessary nutrients for their growth. Fresh hay, such as timothy hay, should be the main component of their diet. This helps to maintain healthy digestion and wear down their teeth, which continuously grow throughout their lives.
In addition to hay, bunnies can also be offered fresh vegetables, such as leafy greens (e.g., kale, spinach, and romaine lettuce), as well as small amounts of pellets specifically formulated for young rabbits.
It’s important to introduce new foods gradually to avoid digestive upset, and to ensure that they have access to clean, fresh water at all times.
Monitoring Weight Gain
During the 1-2 month period, it’s crucial to monitor the weight gain of bunnies to ensure they are growing at a healthy rate. A steady increase in weight is a positive sign of proper nutrition and growth. It’s recommended to weigh them regularly using a digital scale designed for small animals.
If there are concerns about a bunny’s weight gain or if they are not showing interest in solid foods, it’s important to consult a veterinarian who specializes in exotic pets or rabbits. They can provide guidance on adjusting the diet or addressing any potential health issues.
Lop, Rex, and Other Breed Differences
It’s worth noting that different bunny breeds may have slightly different growth patterns and nutritional requirements. For example, some breeds, like the Mini Lop or the Rex, may mature at a faster rate compared to others.
It’s always a good idea to consult breed-specific resources or reputable rabbit breeders for more information on the specific needs of your bunny’s breed.
Understanding the transition to solid foods during the 1-2 month period is essential for the overall health and well-being of bunnies. By providing them with a balanced diet, monitoring their weight gain, and considering any breed-specific differences, bunny owners can ensure that their furry friends grow into happy and healthy adults.
3-4 Months: Entering Adolescence
As bunnies reach the 3-4 month mark, they are entering adolescence, a crucial stage in their development. During this time, they undergo significant changes in their physical appearance and behavior. Let’s take a closer look at what happens during this period.
Rapid Muscle and Skeletal Growth
One of the most noticeable changes in adolescent bunnies is their rapid muscle and skeletal growth. They start to fill out and develop a more mature body structure. It’s fascinating to witness how quickly they transform from cute, fluffy balls of fur into sleek and agile creatures.
This growth spurt is essential for their overall health and agility.
According to research conducted by The House Rabbit Society, bunnies can gain up to 1-2 pounds in weight during this stage. However, it’s important to note that the growth rate can vary depending on the breed and individual bunny.
Sexual Maturity and Breeding
Another significant aspect of adolescence in bunnies is the onset of sexual maturity. Around 3-4 months of age, both male and female bunnies become capable of reproduction. It’s crucial to separate bunnies of opposite sexes during this time unless you intend to breed them responsibly.
Female bunnies, also known as does, can potentially have their first litter as early as 4-5 months of age. However, it’s generally recommended to wait until they are at least 6 months old to prevent any health complications.
Coat Changes in Rex and Wool Breeds
In addition to the physical changes in their bodies, certain bunny breeds, such as Rex and Wool breeds, undergo coat changes during adolescence. Rex bunnies, known for their velvety fur, may experience a slight change in the texture and density of their coat during this time.
Similarly, Wool breeds, like the Angora, can grow a more abundant and luxurious coat as they enter adolescence. This is due to the activation of their secondary hair follicles, resulting in an increase in wool production.
If you have a Rex or Wool breed bunny, it’s essential to provide regular grooming during this period to prevent matting and maintain their coat’s health and appearance.Remember, each bunny is unique, and their growth and development can vary. It’s always a good idea to consult with a veterinarian who specializes in rabbits to ensure your bunny is growing at a healthy rate and receiving the appropriate care.
5-8 Months: Reaching Full Adult Size
During the period of 5-8 months, bunnies undergo significant growth and development, gradually reaching their full adult size. This stage is crucial as it marks the transition from adolescence to adulthood for these furry creatures.
Slowing of Growth Rate
As bunnies approach the 5-8 month mark, their growth rate begins to slow down compared to their earlier months. While they may still experience some growth during this period, it will be at a much slower pace.
This is because most bunnies have already reached their skeletal maturity by this point, and further growth is mainly focused on muscle development and overall body composition.
It is important to note that the growth rate can vary among different bunny breeds. Some breeds may reach their full adult size closer to the 5-month mark, while others may continue to grow until they are around 8 months old.
Consulting a veterinarian or breed-specific resources can provide more accurate information regarding the growth rate of your particular bunny breed.
Establishing Adult Sleep Patterns
As bunnies mature into adults, they also start establishing their adult sleep patterns. While younger bunnies are known for their playful and energetic nature, adult bunnies tend to sleep for longer periods and have more defined sleep-wake cycles.
It is normal for adult bunnies to sleep for around 8-12 hours a day, with their sleep being most active during the early morning and late evening hours.
Creating a comfortable and quiet sleep environment for your bunny is essential during this stage. Providing a cozy sleeping area, away from loud noises and disturbances, can ensure that your bunny gets the rest it needs to maintain its overall health and well-being.
Nutrition Needs for Adult Bunnies
As bunnies reach their full adult size, their nutritional needs also change. They require a balanced diet that consists mainly of high-quality hay, fresh vegetables, and a limited amount of pellets. Hay plays a crucial role in maintaining their dental health and digestive system, while fresh vegetables provide essential vitamins and minerals.
It is recommended to introduce new foods gradually to your adult bunny’s diet to avoid any digestive issues. Monitoring their weight and adjusting their food portions accordingly is also important to ensure they stay at a healthy weight.
Consulting a veterinarian or reputable rabbit care websites, such as Rabbit.org or TheSprucePets.com, can provide more specific guidance on the nutritional needs of adult bunnies, as well as any breed-specific considerations.
9 Months and Beyond: Mature Adulthood
Once bunnies reach the age of 9 months, they enter a stage of mature adulthood. At this point, their bodies have undergone significant changes and they have reached their full size. However, there are still some aspects of their growth and development that continue during this stage.
Full Muscle Maturation
By the time bunnies reach 9 months of age, their muscles have fully matured. This means that they have developed the strength and agility necessary for their daily activities. Bunnies are known for their incredible speed and agility, and this is largely due to the development of their muscles.
They are able to hop, jump, and run with ease, showcasing their natural athleticism.
Dental Health for Adult Rabbits
Dental health is crucial for adult rabbits. By the age of 9 months, bunnies have a full set of adult teeth. It is important to provide them with proper dental care to prevent any potential dental issues.
Regular check-ups with a veterinarian and a balanced diet that includes plenty of hay and fresh vegetables can help maintain their dental health. Avoiding sugary treats and providing them with suitable chew toys can also aid in keeping their teeth in good condition.
Behavioral Changes and Personality Development
As bunnies enter their mature adulthood, they may exhibit some behavioral changes and personality development. Just like humans, bunnies have unique personalities that can evolve over time. Some bunnies may become more independent and assertive, while others may become more affectionate and sociable.
It is important to understand and respect these changes in order to provide them with the appropriate care and environment.
Raising rabbits from newborn kits to fully grown adults is an amazing process to be part of. By understanding the key milestones in a bunny’s development, you’ll know what to expect as your furry friend grows up.
While individual timing varies slightly, domestic rabbits generally reach each growth stage rapidly in their first 6-8 months of life.
With proper care and nutrition, your bunny will thrive as they transition from the newborn phase to adolescence to mature adulthood. Pay close attention to their needs during weaning, sexual maturity, and other critical periods.
Before you know it, your tiny new companion will transform into an adult rabbit, bringing years of joyful companionship along the way.
