Eh I was watching through the anime again (skipped the beginning until after fantasia) and I just finished the Edolas arc.

I suppose they would be pretty secluded, and only Fairy Tail and the people of Magnolia, plus dragonslayers had any contact with them (that we know of). (Ichiya is an odd case maaaaaan.)

But still, a civilization of flying anthropomorphic flying cats whould be hard to hid. Surely some have heard of them.

Sure, if you count the ones that travel with Slayers. The bulk of the nation decided to basically go into hiding, and given that a lot of Earthland, so far as we know, is largely unexplored, it wouldn't be hard to disappear.
