Now its time to decide what kind of wire mesh you will buy. There are several sizes and two basic kinds: galvanized before (which is more expensive) and galvanized after. Actually, galvanized before is also galvanized after. I would only use the more expensive variety if my rabbit cages were more subject to the weather or if I plan to use a lot of water under the cages, such as for washing away the rabbit waste. Our cages are in a barn, so we did not spend the extra money.
For the sides, fronts, backs and tops, you can use 1 x 2 mesh. For the bottoms and baby guards, you can use either x or x 1. We used the x 1 type. Just make sure that the side is placed up so that the rabbits feet rest on the smoother side.
