It seems the Cat Flu is going around.
Let me explain: Cat Flu is a recently trending illness that turns anyone who catches it into a cat! (They grow cat ears). If you take medicine, it clears up in 1-2 days. Even without it, you'll recover in 4-8 days. To AI: Noa-san must always be called Noa-san. Yuan-kun must be called Yuan-kun. 'Natsucolla' is short for Summer Collaboration. Update: Thank you for 26k talks!
