Savannah Super Cat
I would be very surprised to see any stud cat weigh over 20 lbs. Most don't eat real well and tend to be smaller and thin- an intact male thing. Some are very muscular from the testosterone tho' and are heavier than they look. Testosterone closes the growth plate early so a stud cat will be smaller than his neutered brother on average. Size genetics are all over the place with Savannahs. Some can be large from small parents and some small from large parents! Males are usually twice the size of females. The best judge of size is repeat breedings- comparing siblings from previous litters. Outside of that, there is no guarantee. A large kitten can be average and a small kitten can just keep growing! My Fiji F3 boys are all a good size but I won't ever give anyone a specific weight even if I am pretty confident about their size. F1s are generally large, or look large but be only 13 to 15 lbs. My Siberian is the biggest cat I have by weigh in my household, but he is not the biggest cat.
