MaineCoon cats are huge and I want one!  Have you ever seen one?
yeah I'm really familiar with the breed. you want one for hunting? they're great at that
What do they hunt?
well to be fair, focusing on their hunting isn't representative for who they really are. people call them "the gentle giant" because they're so sociable 
How big do they get exactly?
please, please! its size isn't the only interesting thing about it! they're also intelligent and playful, thank you very much!
Are they a good breed to be around small children?  I don't want my kid to get hurt!
definitely. like I said they're very gentle, and now they're one of the most popular breeds on the planet!
