Barley x Ravenpaw is actually canon, one of the Erins (Vicky, i think?) was just like 'oh yeah, theyre married, you couldnt tell?'
i will gladly draw that (my friend will freak out, thats her OTP and she loves it-)
I guess its a bit strange? But then again, people ship humans in media all the time, so why is cats any weirder? This cats might as well be humans by how they behave (organized society, laws, religion, etc)
