Hedgehogs are nocturnal, so that is right that they will sleep in the day. They play at night. You can wake them up once or twice in the day to snuggle, ifyou want to, but not for hours at a time. If you are looking for a pet that will come when you call it, and do tricks, then a hedgehog is not for you. If you are looking for a pet to cuddle with and let crawl on you, then a hedgehog MAY be right for you. Hedgehogs themselves do not really smell, but of course their poo and pee does. As long as you keep that cleaned up, you won't have hedgehog smell. Wood shavings do smell like wood shavings. There is nothing you can do about that. If you choose, you can use fleece which smells like fleece. Just cut some to fit the bottom of you cage and put a few layers on and then peel a layer off each day, put it in a bag and do a load of laudry each week. Hedgehogs need a good wheel to run on, and they poop on their wheels, so those need to be cleaned regularily so that they don't smell. A hedgehog is a very special animal, and with special care, they make wonderful pets, but they are not the right pet for everyone.
