Laura, we have a barrier that is 10 feet separating what was a dining area from the rest of the house. We used the Marshalls play pen panels. We put eye screws in the wall studs near the top and bottom of the panels and attached them with the nylon zip ties. We snugged the ties tight and cut off the ends so they can't be chewed on. Works great, the ferrets can see *out*, we can see them. I can remove the barrier if needed to clean or move something in/out. Easy to step over. I will admit to one issue, I have two, big young rescue boys that can get over the top. We solved that by putting the light weight 3" drain pipe over the top rail. Easy to slit with a skill saw, Home Depot will cut for you if needed. Not the most attractive, but it works..... Ardith [Posted in FML 7066]
