Can Half Maine Coons Grow To The Maine Coon Size?

Can Half Maine Coons Grow To The Maine Coon Size?

Maine Coons can be large cats.

Some are small, but in general, they’re known as a large breed.

Normally it’s talked about from the point of view of a purebred Maine Coon.

Mixed breed Maine Coons are common though.

So, can a mixed or half-breed Maine Coon grow to the normal Maine Coons size?

Maine Coon mixes can grow to be large cats. Their size depends upon the breed that parents the mix kitten. A large breed like a Ragdoll / Maine Coon mix is more likely to produce a large cat than a Maine Coon / Siamese mix.

The Maine Coon is one of the largest breeds of cats there is.

A half Maine Coon does not necessarily have to grow as big because of genetics, but there’s a chance the Maine Coon mix is also a very large cat.

Maine Coons have a hefty frame that can tip the scale at 25 lbs.

Mix-breed cats typically don’t grow to the same length as a purebred cat.

Ultimately it depends on what the mix is, what breed is the other 50% of the DNA.

Maine Coon Mix Size Will Depend Upon The Genetics

Genetics is a funny thing.

There are never any guarantees.

Any newborn receives two copies of a gene.

One from the mother and one from the father.

Genes are either dominant or recessive.

If a newborn Maine Coon kitten receives dominant genes or a dominant and recessive gene trait, then the dominant trait will show.

If the kitten has two recessive genes, the recessive trait will show.

While recessive and dominant genes can be passed along in terms of color, or hereditary health issues, it can also be to do with size.

If one of the parents of a Maine Coon kitten has a dominant gene with respect to size, a mixed breed kitten could well be large also.

The size of a Maine Coon mix is always possible that it will also be a large cat given that the Maine Coon is sharing 50% of its DNA.

Purebred Maine Coons are normally slightly larger than their mix counterparts.

As the Maine Coon is a large cat the chances are that the other parent will be a smaller breed.

As such, most mixes are slightly smaller on average.

The Mixed Breed Part Matters

In biological terms, a mixed breed would be the offspring of cats from two different breeds or a domestic cat and a purebred.

If your cat is a mix of breed lines, it may grow to be large depending upon dominant genes.

So clearly the breed of the mix that parents a Maine Coon mix will be important to whether the mixed kitten would be likely to grow large.

Breeds the same size as a Maine Coon will likely produce bigger mix kittens.

The opposite is also true.

If the breed of the cat that parents with a Maine Coon is a known small breed then the mix might be a smaller Maine Coon mix.

The small gene being possibly more dominant in that case.

The Most Likely Mixes To Give A Large Maine Coon Mix

So the ‘other 50%’ could well determine if the Maine Coon mix will be a large cat.

What are the largest breeds of domestic cats?

The Siberian can reach up to 26 pounds, while the Maine Coon is known more for fluff and the length of his long, poofy tail.

But there’s a wide range of big cat breeds that tend to come in on the larger side.

The large cat breeds that would parent a large Maine Coon mix might be

• Persian
• Savannah Cat
• Norwegian Forest Cat
• Ragdoll
• Ragamuffin
• Chausie

These are large cat breeds that when paired with a Maine Coon will likely give a large sized mix.

The Most Likely Mixes To Give A Small Maine Coon Mix

Conversely, there are breeds that are known to be smaller than average.

Kittens are irresistibly adorable, but every breed has a growth pattern and some don’t grow as big as their peers.

So, some small breeds that may make up a Maine Coon mix then……

• Singapura
• Munchkin
• American Curl
• Cornish Rex
• Devon Rex
• Siamese

Chances are good, that if 50% of the DNA is from one of these breeds it will be a smaller than average Maine Coon mix.

Conclusion

It is possible for a mixed Maine Coon to grow large, but it will take some of the traits from breeds that are known to be larger than average.

A Maine Coon breeding with another breed of compatible size will more than likely produce larger offspring.

If a Maine Coon breeds with a known smaller breed then the mixed Maine Coon will likely be smaller than a purebred.

Genetics plays a large part in what determines a cat’s size.

Large breeds breeding with other large breeds is what will most likely determine that a mix isn’t smaller than a purebred Maine Coon.

Remember, gender can play a large part in relation to cat size, with females being typically 10 to 20% smaller than their male counterparts.
