This is my first post on this forum so hopefully this is in the right place. I am new to raising rabbits and I have a couple of questions about predator protection. I just recently found some cages on craigslist for a great deal but the bar spacing is 1x4. What should I do to make this better withstand predators? I have 1/2x1/2 hardware cloth I started putting around the base and it seems really secure. How high do I need to make it? I live in the country and probably have a lot of predators including raccoons. Any help, tips, or advice would be super appreciated!
