i just built a cage for my guinea pigs but its kinda wide and obnoxious so i wanted to make a 3 ft wide cage but have it with multiple floors so it'd be like 5-6ft tall. What would be the best way to build this. i was thinking about using an old computer desk we just took apart, made out of that fake wood(laminate?), and then layering something over it so that it doesn't get ruined, and making doors with wood frames but a wired panel. does this sound like a bad idea or good? Would it be bad if the piggies chew on that?
