Couldn’t disagree more in my experience. Good breeders don’t allow any kind of close familial ties . Our last two Maine coons lived much longer than that . Our white boy ( and whites are thought to be the most prone to issues ) was 19 when we lost him and his brother 17.
The big silver tabby weighs about 13 kilos my black smoke about 10 or 11 and our kitten is about 8 kilos . Most domestic cats have matured fully by 18 months. Maine coons don’t stop growing until they are 4 or 5
