Ok, I am thinking about making custom cages for all the critters (except fish and dog....) and am starting to gather ideas of DIY cages, and was thinking also of getting a couple more beardies in the future. So I like the cage posted on this website: http://708designs.netfirms.com/customcage/customcage.htm to do on the bottom, then i was thinking about putting one or 2 cages on top and stacking. the other option i thought about was doing cages by design which i will probably do for my boyfriend's ball python (he wants to have it prominently displayed in the living room and doesn't like any of the cage ideas i have come up with so far). Does anyone have any ideas to make stackable cages that won't be too heavy? Also, i've seen some DIY cages that have swinging doors, which to me would be a little easier when you go to clean, does anyone have opinions on that or have any idea on how to accomplish that feat? I am open to any suggestions, it will be a couple of months before i will be ready to go out and start building but i want to have ideas all ready to go. Also, can you use deck sealer/stain or would it possibly harm the beardie? Any advice would be so helpful or even links to other custom cage designs.
