How to Tell How Old a Baby Rabbit Is?

Let’s find out the age with the visual clues and developmental stages of the bunny.

The First Days 

Newborn kits are fragile and reliant on their mother for survival. They have closed eyes and sealed ear canals, making them blind and deaf. They are small, hairless, and may appear wrinkled. They are immobile and primarily nurse and sleep, relying solely on their mother’s milk for nourishment.

Eyes Partially Open

How to tell how old a baby rabbit Is with the eyes? Around 7-10 days of age, kits begin to open their eyes, revealing cloudy or bluish eyes. They may also open their ear canals slightly. Kits show increased movement and explore the baby rabbit nest, remaining close to their mother. They continue nursing for sustenance.

Eyes Fully Open

When do baby rabbits open their eyes? During the second week, most kits fully opened their eyes, resulting in clear vision, open ear canals, thickening fur, and increased mobility. This stage allows them to respond to their surroundings, hear sounds better, grow their fur, and venture further from the nest.

Ears Erect 

Kits’ ears, initially floppy or drooping, become more alert and erect around 10-12 days, leading to increased exploration within their environment.

Fur Growth

Kits develop a denser coat between 7-10 days, covering their once-bare bodies with a thicker fur layer and forming distinct patterns and colors.


Kits reach 2-3 weeks of age and begin to explore the baby rabbit nest area, becoming more mobile and potentially nibbling on solid food while nursing.

Fur Patterns 

By 3-4 weeks, fur patterns and colors in animals become more distinct, aiding in breed identification.


The growth of front teeth in rabbits, which begin around 2 weeks, can indicate their age, as these teeth continue to develop as they mature.


Kits are fully weaned and transition to solid baby rabbit food between 4 to 6 weeks, consuming pellets, hay, and fresh vegetables for nutrition. They may occasionally nurse for comfort.

Sexual Differentiation 

Males typically have a visible testicle sac, while female rabbits have a slit-like vulva, distinguishing them between 4 to 6 weeks.

The age ranges provided are a general guideline for estimating a baby rabbit’s age, but individual variations exist. For precise age determination or finding an orphaned kit, consult a veterinarian or local wildlife rehabilitator. Approach young rabbits with care and sensitivity, avoiding excessive handling.

What to feed a wild baby rabbit?

Feeding wild baby rabbits should be done cautiously, as they have specific dietary needs. They should be left in their mother’s care for optimal nutrition.

This advice should be tailored to the rabbit’s age, overall condition, and specific requirements, including the crucial aspect of How to Tell How Old a Baby Rabbit Is. Here’s what to feed a wild baby rabbit:

  • Before feeding a wild baby rabbit food, consult a professional wildlife rehabilitator or veterinarian for guidance based on the rabbit’s age, condition, and specific needs. 
  • Keep the rabbit in a warm, quiet environment with a cooling area. 
  • If the kit appears dehydrated, provide rehydration solutions specifically designed for infants. 
  • If the baby rabbit is less than 2 weeks old and has not been weaned, feed it a specialized milk replacement formula. 
  • Feed small amounts every 2-3 hours, allowing the rabbit to suckle at its own pace. Transition to solid food around 2 weeks of age, introducing high-quality rabbit pellet, fresh hay, and water. 
  • Gradually reduce milk feedings as the rabbit transitions to a solid diet. Avoid human interaction to reduce stress on the wild rabbit. 

Seek professional help to evaluate the rabbit’s health, provide feeding instructions, and ensure proper care until it’s ready for release back into the wild. Never attempt to keep a wild rabbit as a pet, as it is often illegal and has specific needs that cannot be met in a domestic setting.
