Here's why:
* Rabbits are very protective: Mother rabbits usually build a nest in a hidden spot, often lined with fur and grass.
* They only visit their young briefly: Rabbits only visit their babies a few times a day to feed them. They don't want to leave their scent in the nest which could attract predators.
* Staying warm: The nest provides insulation and keeps the babies warm.
If you see the babies, the best thing to do is to leave them alone. The mother will be back to care for them.
Important Note: If you are concerned about the babies' safety, you can contact a local animal rescue or wildlife rehabilitation center for advice. They can help you determine if the babies need assistance.
