Up, up!! Good girl Mittens! Such a good cat, now, flip!

Ccino was playing with a cat, being an expert cat trainer. The cat was a domestic tuxedo cat, and he was practicing some tricks in his room. He dreamed of being able to train a bigger animal, like a lion, or a tiger. The thought itself excited him. However, a sudden knock popped his daydream, and he stood up, going to the door.

Hmm? Who is it?
