I've been doing some research on caging requirements of dwarf hamsters, and have tried to identifiy the pros and cons to each cage type.
METAL CAGES:
-Good ventilation
-Durable
-Hams can kick stuff out of them
-Easier for dwarfs to excape from than glass
GLASS/PLASTICTANKS:
-Gives you the best view of animal:
-Cheapest to buy
-Nothing for the hamster to chew up
-Hardest to excape from
-Less ventilation
-Big glass tanks are hard to handle and clean. I mean, just try lugging a big twenty long into the laundry room once week. Sooner or later, you'll have problems in the form of a hurt back or a shattered hamster home (and cut up hands perhaps). If I use glass, I plan to stick to ten gallons.
HABITRAILS:
-Enrichens the hamsters' environment
-Gives a good view of the animals
-Less ventilation than metal cage
-Dwarf hamsters have trouble moving through them depending on the design.
-Most likely to be excaped from (in my opinion).
