I have some kits which I expect will be venturing out of the nesting box soon. I wonder if when they do so if their little feet might slip through the wire mesh floor and possibly hurt them. I have the standard wire mesh flooring used in many rabbit cages, what is I am guessing is the one half inch squares. This is the wire mesh found at Home Depot, Lowes, etc. Should I be concerned in this regard? Also, do I need to keep returning the kits to the nesting box or should I allow them to stay out of the nesting box once they've ventured out the first time? I looked but could not quickly find this same question posted in any forum here. Really appreciate any advice.
