You might want to get some toys for him, mine loves to roll jingly cat balls around! Also, make sure he has plenty of room to run and/or a wheel. 11" diamater wheel is a good size. They need plenty of excersize.
Meal worms are an essential to a hedgehog's diet. They contain nutrients that hedgehogs need to be healthy. 2 or 3 a day will keep the doctor away
Best of luck with your new pet!
