Kritter Koncepts, the other half of The Ferret Nook in Wisconsin, sells
well-made large hammocks and cubes.  I've had as many as five fuzzies in
a hammock.  Check out their on-line catalog at
http://kritterkoncepts.net/catalog/
 
They sell wonderful cages and playpens they make, too.  Oh, you have to
click on the "what's new" arrow for the rest of the catalog.  I think you
will be pleased with their products.
