Rabbit Cages Calgary How Can I Turn My Cages Into A Rabbit Hutch?

How can I turn my cages into a rabbit hutch? - rabbit cages calgary

I have two 30 x 36 "cages for rabbits, but I need a rabbit hutch. I read online that you concrete blocks and plywood to the sides and top only stack, but it seems not very stable. Any ideas? I need to know how to make a nest box build.
