I'm not sure. Hopefully someone more knowledgeable than me will be along to give you an answer, I'd just like to advise that unless the rabbit is a cuddle monster (and if so, well done, you've found the one in a thousand who is!), it's best not to handle them unless absolutely necessary, i.e trips to the vet. Certainly not advisable to allow young children to handle them, they often don't know their own strength and it can quite easily end in either a sore rabbit or a chunk of baby's finger missing!
