Why did you get a kitten if you don't like animals on your bed? And is it really so hard to brush off some fur? It really pisses me off when people get cats or dogs and confine them to one part of the house, or try to stop what they will naturally do. Did you even think about what it would be like to get a kitten? Cat's like elevated positions, it makes them feel safe and like they have some amount of control. If you really want him off your bed just close your door or something.
