Y'know that joke about shaving your cat's butt and teaching it to walk backward? The vet more or less did that to Violet. Her new steampunk plastic Elizabethan ruff keeps her from picking at the stitches on her shaved butt, and she occasionally walks backwards in an attempt to back out of her new fashion accessory. But, she's now abscess free, if somewhat frankenstein-looking. Poor thing.
