My cat is a main (expletive deleted) and weighs 40 pounds.
Yes, they're one of the largest domesticated breed of cat. Even so, 40 pounds is larger than average!
I feed her a lot.  Do you think i am over feeding her?
As long as she gets enough exercise, it should offset the food intake. These cats are natural hunters, so they really enjoy their exercise.
She gets lots of exercise chasing mice.  She must catch about 20 a day.
Well there you go! It's actually a bit of a coincidence, because they're the state cat for the state of Maine, which is right next door to where I live in Canada!
I like Canada.  Hockey and beer, two of my very favorite things.  
That explains why you like big, rugged cats. Perfect for the Canadian climate!
