You are looking for a "
Main Coon "
Quote: "Although the Yankee myth of 30-pound cats is just that, a myth (unless the cat is grossly overweight!), these are indeed tall, muscular, big-boned cats; males commonly reach 13 to 18 pounds, with females normally weighing about 9 to 12 pounds. Add to that two or three inches of winter coat, and people will swear that they're looking at one big cat."
I had one that was 24 pounds. Yes, he was overweight.
