* Bunnies are clean animals: They are very meticulous about keeping their nests clean.
* They pull fur: Mother rabbits pull fur from their bellies to line the nest and keep the babies warm. This fur is carefully placed and arranged, not just a random clump.
* Babies are born hairless: Baby bunnies are born without fur. They develop their fur gradually over the first few weeks of life.
So, while you might see some loose fur around the nest, it won't be a big, messy ball. It will be a carefully constructed, warm, and cozy bed for the newborns.
