Looking for input/advice/etc. from anyone who has built their own cages. How would you go about creating a large, fairly lightweight but durable indoor aviary or flight cage? I'm thinking 6' long x 2.5' wide x 4' high, preferably with an extra 1-2' of shelf space underneath for food/toys/etc. storage. (I wanted to just buy one but can't find one anywhere near that big on my budget, lol.)
I was thinking of upcycling an old cabinet or entertainment center, but don't know if it's better to just start from scratch? I've also seen stuff using PVC? Ideas welcome.
