What is the term used for a doe nursing young rabbits that are not her own?

The term "fostering" is used to describe when a doe nurses young rabbits that are not her biological offspring. In the context of rabbit care, fostering occurs when a doe accepts and cares for kits from another litter, usually because the biological mother is unable to nurse her young due to various reasons such as health issues or insufficient milk supply. This practice is beneficial for the survival of the kits, as the nursing doe provides the necessary nutrients and warmth that are crucial for their growth and development.

While adoption and surrogacy involve similar themes of caring for young that are not one's own, they are typically used in broader contexts or with different implications in animal behavior and reproduction. "Mothering" generally refers to the overall act of a mother caring for her young, but does not specifically denote the act of caring for offspring that aren't hers. Fostering is the most precise term in this scenario, making it the correct choice for describing this particular situation.
