Yes, bunnies can have twins. It is common for rabbits to give birth to a litter of kits, ranging from one to several babies. Twins are not uncommon in rabbit pregnancies.

You should separate them before she has the babies because almost right after she gives birth she can become pregnant again and you will have bunny explosion!!! Separate them!! The world does not need more bunnies!!!!! :) hope that helps.
No, they do it by thereselves, but its nasty when they eat a ball of goopy gross stuff after they give birth, bleh!
When a dog gives birth, it is called whelping.
