My Maine Coon, Abby, is almost 3 years old. She is the light of my life.
Her color is officially "blue." She's a big girl, but not huge. She weighs about 13-14 pounds. I got her when she was 8 weeks old from a breeder here in Indy after losing a precious mixed breed cat to heart problems. I had done some research on Maine Coons and had decided that was the way I wanted to go.
She has the best disposition. She is just a sweetie pie. She loves our 3 German Shepherds, plays with them (tough - like a dog), eats with them, sleeps with them, etc.
Here is a picture of her "holding her own" as a tiny kitten up against all 90 pounds of Opal, our White German Shepherd:
She cuddles on my lap when I watch television and under the covers up against me in bed at night. She follows me from room to room, like a dog.
Maine Coons "talk" instead of meow. They kind of chirp. It's a very different sound. Abby is particularly talkative.
The only negative that you need to know about is coat/fur care. I've had other long-haired "mutt" cats before, but this fur is different. It's very soft, fine and "clumpable." If you don't brush it, it will mat up. That's no fun.
