Aw, what a cutie!

As for food, when you buy rabbit pellets its best that you buy pellets with 16% protein, 18% is usually too high for most rabbits. Hay is always very good, carrots, pears and apples are my buns favorites. If he feels thin I highly recommend rolled outs and dried whole wheat/brown bread to help put on some weight. If you have any other questions don't hesitate to send me a PM. I've had rabbits nearly all of my life.
