Baby bunnies are most commonly referred to as kits. But they’re also called kittens. First few litters will start small but the quantity will grow with every following litter. When breeding the offspring of rabbits that have big litters you may see an 8 or 9 kit litter right away. The amount of rabbits in a litter will continue to rise topping out at approximately 10-14 kits once things get rolling. Not all rabbits will be able to achieve these numbers.
