Here's a breakdown of the timeline:
* Days 1-3: Kits are born with very sparse fur, almost naked.
* Days 4-7: Fur begins to grow quickly.
* Weeks 2-3: Kits develop a thicker coat, but it may still be patchy.
* Week 4-6: Kits have a full, dense coat of fur, similar to adult rabbits.
It's important to note that these are general guidelines, and the exact time it takes for a kit to develop fur can vary slightly depending on factors like breed, individual health, and environmental conditions.
