Thread: Are these Maine Coons? Pic attached.

first thing I would say is that at that age they grow reaaaally fast - mine grew the size of my previous cat (who admitedly was rather on the small size) within 6 months! and then doubled again...
also, their tail is very long - may be they're a little bit young for this, but if within a couple of weeks you notice that they have a reeeeallly long tail compared to their body.... then I'd say that's a no brainer...
