I'm building a custom HDPE enclosure for my boy Ozai - it'll be 9ft long, 2ft wide, and 2ft high. How much ventilation do you think I should add? I'm thinking a 2in x 9ft screen strip in front that goes along the upper edge above the doors and maybe a vertical 3in strip in the front center - think that would be good or do I need more on the sides? Or is it too much? It'll be up against a wall so I think anything in the back would be pretty useless.
I'd put vents on the ends too so there is cross ventilation. You can can find screened vents at home depot, just cut a hole and pop them in. Lots of sizes to choose from.
