Why do mother rabbits nurse their young only briefly each day?

Mother rabbits are considered "absentee parents" who typically nurse their young only once per day for just a few minutes. This behavior is an evolutionary strategy to protect their offspring; by spending very little time at the nest, the mother avoids drawing the attention of predators to the vulnerable, altricial kittens.1

To compensate for these brief nursing sessions, rabbit milk is exceptionally nutrient-dense and ranks among the richest of all mammals, allowing the young to grow rapidly despite the limited contact.1
