Does Lilly sound like a Maine Coon?

In January, I was at a boat show with my family. A local shelter was there, and in one of the cages was the cutest kitten anyone could have ever imagined. So, of course, I got her. The shelter said she was a domestic long hair (dlh), and I had no reason to doubt them. I had never heard of a Maine Coon. When I brought the kitten home, one of my neighbors said "That's a Maine Coon if I ever saw one!"
So the research began.
Lilly, my kitten, was said to have been brought to the shelter on September 23rd of last year, but when I took her to the vet, he argued with the date. Her teeth showed him that she would have been born only fourteen weeks before our appointment--so roughly in late October. I selected October 26th to be her unofficial birthday.
So, we'll say she's about 8 months old. Again, no way for me to really know. And maybe the vet was wrong and she was brought in September 23rd, so she'd be about 9 months old.

As I've read, Lilly has all the characteristics of a Maine Coon--a poofy, squirrel-like tail; long hair all over her body; hair coming out her ears in a lynx-like fashion; long hair between her toes; wide, bright eyes; and before summer, she had a thick 'collar' of hair around her neck, making her look like a little lion. She's also super affectionate, really really smart, and she doesn't meow--she makes little clicking noises, and squeaks. We keep joking that she's not a cat at all, but really some kind of squirrel.
However, I've also read that Maine Coons get fairly large. And I know the males get larger than the females--but Lilly, at 8-9ish months old, is only 5 pounds. Is this normal?
I'm not overly concerned with it, I was just curious. I've looked online, but most of what I've found is tracking the males, because they are the big guys.

Thanks for any help :)

P.S. I'm attaching some pictures for everyone to see--She's also my profile picture.

Does she like water & chirp alot :LOL: she looks lovely :nod:

Oh she is lovely! No wonder you couldn't resist! She looks like a MC to me but I'm no expert. My 2 MCs are quite different to each other in stature. Both are girls and one is very fat with a shorter body and the other is long bodied but a little leaner. Basically it's like having 2 large kittens in the house although they are both 2ish!

She doesn't make a ton of noise, but when she jumps around or wants your attention it is a chirping noise. She does seem to like water, as well.
She's pretty adorable, but I'm biased... I never knew what a MC was until I got her, so I thought I'd get some opinions from people who know their stuff!

Hi there, thanks for posting the pictures of Lilly she looks very cute indeed ! Again, I'm no expert but she does have some characteristics of the MC, so if I was taking a wild guess I would say she is more likely to be part MC. All MC's vary in size and yes females are normally quite a bit smaller but I would say 5lb was small for a 8/9 month old female MC. I know one thing, she is a very lucky little girl to have found you and you her :)
