It's actually a little funny in the sense that I technically already feel a strong connection to rodents, especially rats; my medieval reenactment name was "the Rat" and I do have, y'know. Big teeth and ears and all that. But I don't know what the sort of cute noise a rat would make - I don't think I could have a proper fursona because I wouldn't want it to be cute and all needy of attention and all; and I wouldn't want to RP as a sort of anthropormophed rat either or any animal either. Especially since I wouldn't exactly be on the cute-and-attention-needy side.
