Poor you.. I suffered this a long time ago... rabbits love to pull on carpets for some reason.
My whole apartments carpeted except the kitchen and bathroom. I basically had to duct tape all the edges
of my carpet so that the rabbits wouldn't chew on them. Other than that I can't really think of anything,
else. You can try giving them more toys to play with, toilet rolls, paper towel rolls, cardboard boxes.
They're just bored, bored rabbits = bad rabbits.
