It depends on how old Maddie is, because Maine Coons are not considered "fully developed" until they are at least 4 years old. Our male, Rocky Raccoon (also known as The Rock) is already 23 pounds at the age of 3. I wish I could say that was all muscle and bone, but unfortunately he is like too many neutered males, he lounges regally and waits for the food to arrive
His sibling, Sascha, is a dynamo who has the body and fur of a mink but weighs 12 pounds. Both of them have the huge ears and snowshoe feet, as does T'Pau, Queen of the Universe. Maine Coons love to follow their person around the house, right at your heels, so you have to learn to be very careful about stepping backwards or walking down a hallway in the dark. They make a shocked little squeek if they get stepped on (Coons do not have a meow like other cats) and they look so grief-stricken that you would hurt them, it will break your heart and you will smother them with apologies and pets.
