Minecraft wiki entry for Rabbit, associated text: Baby rabbits usually inherit the same type of fur as one of the parents (47.5% chance of each), but there is a 5% chance for the baby to have the fur type matching the current biome. Baby rabbits grow to adulthood after 20 minutes, although their growth can be slowly accelerated using carrots, golden carrots or dandelions; each use reduces 10% of the remaining time to grow up.
