Here's why:
* Protection: The nest provides a safe, warm, and concealed environment for the vulnerable kittens.
* Warmth: The mother rabbit lines the nest with fur and other soft materials to insulate the kittens and keep them warm.
* Camouflage: Nests are often hidden in dense vegetation or underground burrows to protect the kittens from predators.
* Nurturing: The mother rabbit spends most of her time in the nest with her kittens, nursing them and keeping them clean.
So, while rabbit nests may appear simple, they are essential for the survival of baby rabbits.
