I've had my girl a full year now & I am still not used to it.
Her chirrup, me & hubbie agreed last night, sounds like "awwwww" as in the same intonation in "but awwww mum that's not fair!" so we always assume a chirrup means something's wrong!!!! She's a proper little chatterbox. Never heard a meow though.
Anyone else's coonie do the same?
