This is Annie Mae (a play on anime, since her face is so vivid and stylized). She was born over an hour after her four siblings! She had a condition called cerebellar hypoplasia or "wobbly cat syndrome" that affected her balance and muscle control. This is not a dangerous condition it turns out, and over time wobbly kitties learn to compensate. These days you can barely tell she has it, but as a kitten it made walking and nursing a real struggle. I remember that she grew so frustrated, she retired into this fleece clamshell and spent most of her time there in solitude for about a week and a half. When she finally emerged, somehow she had made huge leaps in controlling her movements. She's a wonderful cat with a will of iron, and she's definitely the household administrator. (We say, "Annie makes the trains run on time.")
