Aside from the cage being a glass aquarium it looks like it is WAY too tiny. The igloo also looks too small for your hedgehog. Hedgehogs need at least 2 square feet of space in order to fit their hiding place, their wheel, and their food and water dishes. If you use an aquarium, which I and most everyone on the site don't recommend, then it needs to be about 30 gallons in order to be big enough. You are better off using a 126qt. Sterilite plastic bin from Wal-Mart. It costs about $8 and can be modified to include vents and air holes. Some people even link 2 or three plastic tubs with dryer vents or 4" pvc pipes. Or if you aren't a DIY person then I suggest buying a guinea pig or rabbit size cage from a pet store as long as it has a solid bottom. Something like this works well and is large enough to accommodate a proper size wheel. http://www.petsmart.com/product/index.jsp?productId=2753290&lmdn=Pet+Type
