A brief list of things needed right away is covered in section [4.5], and is
meant as a getting started list.  This section, and the ones that follow, are
meant to provide information in greater detail.

There are only a few things that are essential to keep a pet hedgehog.
Basically a warm place to live (either a large cage/pen/aquarium, or a room
-- if you want to let your hedgehog run free), a food dish (preferably one
that is not easy to tip over), a water bottle, such as for Guinea pigs,
(water dishes can tend to become soiled and baby hedgehogs can easily drown
in them, but adults often like them), and last but not least, something big
enough for your hedgehog to hide in as a den.  Of course food, water and
other treats are a given!

It is also a good idea to have a shallow litter box or pan (although not all
hedgehogs seem inclined to use them), and some type of bedding (aspen
shavings, clean straw, etc., but NOT cedar [5.3]).

An exercise wheel [5.6] and [5.7] (big enough for a hedgehog) is also
strongly recommended -- especially for hedgehogs that don't have the run of
the house.  Hedgehogs tend to be surprisingly energetic, and need the chance
to use up some of this energy.  In addition, it appears more and more that
hedgehogs who have and use wheels live much longer and generally seem not to
come down with some of the more common serious ailments, such as Fatty Liver
Disease.  Because of this, I am quickly reaching the opinion that a proper
wheel is more of a necessity than a luxury.  Given how easy (and even fun) it
is to make a wheel, there really is no excuse for not having one.
