First, get the baby rabbit contained
To keep the baby rabbit safe while you figure out how to help them, put them in a small cardboard box with a soft towel or t-shirt. Even when indoors, or on a warm day, babies can get cold or even hypothermic, so give them a heat source:
- a clean sock filled with dry, uncooked rice, and microwaved for one minute
- a plastic bottle or jar with a tight-fitting lid from the recycling bin filled with hot tap water and wrapped in a tea towel or face cloth (secured to the box so that it does not squish the baby)
- an electric heating pad set to “LOW” and placed under half of the box.
- chemical hand warmers (e.g. Hot Paws) that stay warm for up to 8 hours
Do not give the baby any food or water – right now keeping them warm, dark, and quiet is more important.
