Extra-large is a specialty size for very large cats, typically big-breed males. These cats may start around 20 pounds and range up to 40 pounds or more, with a torso length of at least 19 inches from base-of-neck to base-of-tail. If your cat does not meet the size criteria  for XL, you should order large instead.
