Yes. All the ones who have starved are good eaters. In fact, they get a bit chubby for a few years, and then slim down again, in my experience. Right now, Miss Hissy Slashy and little Shadow are in their tubby phases, although Hissy is a naturally big girl, and Shadow is already getting thinner. My Rocket and Lucas (prince of darkness) have lost their post-starvation weight.
Methinks there's a British car fan in your house.
