So I'm planning on building a cage for my 2 Flemish Giants, they are going to be staying inside in my bedroom with me. The dimensions for the cage is going to be 3' x 8' and 4' high. The thing is that I will be making the frame out of PVC piping, and I'm just wondering if anyone has an idea of how this will hold up to chewing? A few years ago I talked with a rabbit rescue that uses PVC pipe to run electrical wires through so rabbits can't chew them. Would they be able to eventually get through long term? I plan on adding a lot of toys and chew blocks to keep them distracted. Also, I plan on making the shelves out of plywood, I figure I can always easily replace them if they are chewed. Anyone have any suggestions on something better I can make the shelves out of? Or recommend any specific type of wood that would be best? I know to avoid cedar, but when I was looking at wood at the store, for the most part they don't say what type of wood they are made of. Also, do you guys think I should add ramps for the shelves or would the rabbits probably be able to hop up without them? I don't want to take away to much cage space building ramps. I drew up a draft of the design plan, nothing is definite yet, I wanted to get some opinions on the idea. Any suggestions are welcome Thanks!
