Not the Carpet!
Vampires are very, very, hungry bats. Their diet mainly consists of one thing, and it is not that simple to get without others alerted. Edward already released the secret of his entire family and friends, which understandably made many angry.
But what are they to do, it’s become a publicly open secret. So when Bella met other vampires, she cut herself allowing a drop of blood to fall onto a carpet. It makes sense why these vampires would go bananas over that spilt blood, they don’t want their carpet to be dirty. Carpet cleaning is a hard task, especially if there is a bloodstain.
