My mom had a Maine Coone when I was very little.
That's cool! It's one of the largest breeds of cats! Did you like it?
I dont really remember him actually I was really young. What kind of coat do they have?
Well they have a rubust bone structure and an uneven layered coat  with longer hairs with a silky undercoat.
I think I remember him with long hair. Are they a friendly breed? 
I think so! They are commonly know for being intelligent and playful! They definitely have that gentle personality.
Very nice. They seem like they would be a popular breed.
Correct! And it's one of the oldest natural "native" breeds in North America! What a cool feline!
