i'm not sure if they would chew through it. but i don't think it would be very sturdy for the size cage we are building. our new cage will be 4'wide X 6' tall X 2'deep.
we did find some plastic mesh/hardware cloth with 1/2" x 1/2" holes and that seems to work well as long as you have extra bracing for sturdiness. however, since it's plastic, it won't hold a whole lot of weight and depending on what toys, etc you're hanging in your cage, it may tear through. not sure though.
