Thread: How big is your Coon?

Most people are very surprised when they see Willow (8,5 kgs) or Indy (7kgs). They are both adult Maine Coon males, and seem huge to most people who aren't used to seeing big cats like this. Especially Willow is quite impressive, and everyone who comes to visit can't help but saying how beautiful he is.
Esme is still a kitten, she weighs about 3kgs now. If she continues to grow as fast as she's doing now; and if she's going to take after her parents and grandparents, she's going to be a huge cat as well - even for a girl. If she follows her mother's and grandmother's example, she'll turn out to be about 6 to 7 kgs as well...

We have four MCs. The two girls are probably full grown now at just shy of 5 and 4 years old. The older one is 11.5-12lbs (5.3kg) while the younger is 13.5-14lbs (6.2kg). The two boys are still growing. The older one, 18mos, is around 18lbs (8.1kg). The younger one, 6mos, was 10lbs (4.5kg) a few weeks short of 6mos. From this you can see that the big males grow rapidly for the first months. I think that the older one was 12 lbs at 7-8mos., and you can see that he put on only 50% more in the following 10mos.

People do always think they are big, but we are used to them so they don't seem large to us anymore. When we took in our first MC mix, who was only 13.5-14lbs, we thought he was huge--as did everyone in the neighborhood. Now he would be nothing next to our big boy. Still, he was the neighborhood alpha male stray--beat up many cats before we took him in. The larger female goes outside with me (on leash) and people ooh and aah over her. One of our neighbors always says that she is the most beautiful cat she has ever seen. The brown tabbies look pretty spectacular when they are outside--something about the natural light makes them look more like wild cats.

I am quite surprised by the sizes,
I thought they took 4 years to reach eventual weight and height, ours is 11lb now at 9 months and it seems that she is not far off fully grown considering the replies on here,
I presumed she would keep going - do you think she will slow down quite a bit now and just fill out?
Does anyone know the average size of a female maine coon fully grown?

I've just heard from the breeder tonight and Gryfn at 5 weeks old is 600grams.

About three to four years it takes!

Many say about 15lbs max for a female but considering mine is still growing at 14lbs I'm not too sure!

Just about 1/2 way down the page is an 'average weight' chart. Not sure how accurate it is, but its there

They definitely slow down. Our older male was around 12lbs at 8mos. and is now 18lbs at 18mos. Our female who is nearing age 4 added around 1.5lbs (<10%) between ages 2.5 and 3.5yrs. They tend to get very long and lean first and then fill out. Our 6mos male's rear feet are just as long as the 18mos old male's. They look in proportion on the older male--the kitten looks somewhat like a bunny (as the older male once did).

Your girl does sound large!
