Leon Katze is a 2014 introduced and all around character. Leon is the son of the cat from Cat and Mouse in Partnership.
He was a community OC, but Grimm Master adopted him.
Leon is tall, with long brown hair, green eyes, and a tan complexion. He has brown cat ears and whiskers. He wears a red and green striped sweater and blue jeans.
Leon is skittish, chipper, and friendly. He is always willing to talk to people. He's also fond of mice and wants to get closer to them, but he feels that being a cat keeps him from befriending them. He disagrees with the idea that cats and mice cannot be friends. Leon is also fairly religious and often attends church on Sundays.
A cat and a mouse, contrary to the custom of their kinds, become friends, such good friends that they decide to share a home. That they might have something to fall back on in time of need, they buy a pot of fat and hide it away in a nook of a church for safekeeping. After a short time, the cat tells her housemate that one of her relations has given birth and that the mouse's friend has been asked to be godmother. Instead of going to a christening, though, the cat goes to the nook of the church and eats the top layer of the fat in the pot. When the cat returns home, the mouse asks the name of the kitten. The cat replies, "Top-off." The mouse remarks that she has never heard such a name.
Soon thereafter, the cat announces that she again has been invited to a christening. On the cat's return, the mouse asks what name was given to this kitten. "Half-gone," answers the cat. Again the mouse wonders aloud at the oddness of the name.
The cat goes a third time to the church, this time finishing off the fat. When the cat returns, the mouse asks the name given at this christening. "All-gone," answers the cat. Again the mouse shakes her head.
Winter arrives, and with it the lean times the friends had anticipated. The mouse proposes a trip to the church to retrieve the provisions stored there. When she beholds the empty pot, enlightenment dawns on the mouse: "First 'Top-off,' " she murmurs, "then 'Half-gone,' and then ..." The cat warns her to say no more, but the mouse persists. The cat pounces on the mouse and eats her up. "And that is the way of the world," the story closes.
