What Makes Them Big?

Because so little is known about their ancestors, it is impossible to completely grasp why these cats grow to be so big.  All that is certain is that they may become quite big and that there is a genetic relationship to their size. There are, however, several other factors that may contribute to their size.


One of the most important factors influencing a cat’s size is genetics. While this is a bigger breed in general, owners should not assume that their cat will grow to be big simply because it is a Maine Coon. Looking at the parent cats can help predict the size of the kitten when it is completely grown. Also, many of these cats may be mixed breeds, which will influence their size.


The overall health of a cat can impact how big it grows. Obesity is the most common preventable condition in cats. This can have an impact on how big a cat grows and how healthy they are overall. In general, Maine Coon cats are a healthy breed. They may, however, have a genetic predisposition to certain health conditions, such as hip dysplasia, heart disease, and spinal muscular atrophy.


Nutrition, along with genetics, is one of the most significant factors in determining the size of any cat breed. Cats require a nutritious, well-balanced diet. This breed thrives on foods heavy in animal protein, such as chicken and fish. They also require tiny quantities of omega-3 and omega-6 fatty acids, carbohydrates, and vitamins (A, B, K, and Niacin). The amount they eat and the quality of their food will have a big influence on how big they grow. Nutrition plays an important role from the first day of their existence till they are senior cats.

Are All Maine Coon Cats Big?

  • Small parents – If your Maine Coon’s parents are on the smaller end of the growth spectrum, you shouldn’t expect your cat to reach the greater sizes that the breed is known for.
  • Mixed Breed – Because their genetics are mixed, Maine Coons of mixed-breed parents cannot be guaranteed to develop into giant Maine Coon cats. It will eventually come down to which genes in these cats are dominant and which are recessive. Although the price of a purebred Maine Coone can be a little higher than a regular cat it’s more likely that a purebred will reach the breed’s typical size.
  • Health Issues – Underlying health conditions may have an impact on the full-size Maine Coon cats. If you have any concerns about the health of your Maine Coons, see a veterinarian as soon as possible.
