Education In Kitten Behavior - Lesson 1

No matter how carefully you trail the cat toy around the floor, the kitten will take the shortest path of interception. If that path happens to be over your bare feet, tough. The kitten will not try to avoid them.

NB. Kittens, when changing from rough, high friction carpet surfaces to smooth, low-friction skin surfaces while in pursuit of cat toys, will not fully retract claws. Said claws resemble hypodermic syringe needles.
