Cages

Your hedgehog's cage should be completely solid-sided. Hedgehogs are very clumsy and poor at climbing, but they don't seem to know that and often try to climb anyway. Generally a climbing attempt will result in an immediate fall which could cause broken bones. Narrow-spaced bars (like in Hamster cages) are dangerous because hedgehogs tend to get their legs stuck in them. Wide-spaced bars (like in rabbit or guinea pig cages) are even worse because hedgehogs can easily get their heads stuck in them, potentially causing a broken neck or even death. While some rabbit and guinea pig cages have a few inches of plastic before the wire, they still aren't fully safe as hedgies will still be able to make it up to the bars by propping themselves up on their igloo or wheel. Make sure that the bottom of your cage is solid too as hedgies will hurt their feet walking on the wire floors that are in rabbit hutches. You also want to avoid any cages with levels because due to their poor eyesight and lack of depth perception, hedgehogs will walk right off any ledge. Levels are only safe if both the upper level and ramp have borders around them. The best cages are plastic totes, glass aquariums, and C&C cages (with high coroplast sides that go up at least 10 inches). ​

Wheels

​Exercise wheels are a necessity. Like cages, they should be completely solid. Avoid wheels with wire or mesh because legs/nails can get caught in them. You also want to avoid sandpaper wheels as they will hurt their feet. The best wheel by far is a bucket wheel - which you can make yourself or order here. They're silent, easy to clean, can be purchased with a litter pan to fit under them, and are the perfect size for hedgies. You can only buy them online but they are worth the wait and cost. This Full Cheeks wheel can be found at Petsmart and is also safe and quiet, but the stand takes up a lot of space and the ridges make cleaning tedious. Similarly, the large Niteangel wheel is a safe, quiet choice but can be a pain to clean. Kaytee Comfort Wheels (12" for adults, 8.5" can work for young babies) are safe and available at most pet stores, but are quite noisy. We use flying saucer discs sparingly in play areas but not in cages due to them being easily broken and some experts believing daily use can harm a hedgie's spine. We don't recommend the Silent Spinner due to the small openings where the two pieces meet, or the Exotic Nutrition wheel due to it being very flimsy and narrow. 

Bedding

There's tons of options when it comes to bedding. Wood shavings like Pine and Aspen are low-cost and work fine as long as the bag says "kiln-dried". Carefesh paper pulp bedding, paper crinkles, and Yesterday's News pellets are all safe options as well. You can use newspaper or shredded documents as long as there are no staples.
If you are successful in litter-training your hedgie, you can just have fleece liners instead of bedding. Fleece is the best fabric to use for this purpose because it does not have frayed edges. We don't recommend using fleece before litter training as you have to move the pee and poo smells to the litter pan and you can't move pee or loose baby poos if they're soaked/smeared into fleece. We find it easiest to start with white Carefresh as you can easily see and move all the pee spots. It also helps to use a different substrate in the litter pan so they can clearly feel the difference in the two areas. 
Avoid cedar bedding (it's toxic to small animals), cat litter (too dusty for a hedgie to inhale), and towels/other fabrics with loops or frayed edges that nails can get caught in.
