Hiya Terry---maybe this will work.  Havn't tried it yet myself but saw a
picture somewhere of a possible solution.  Best way to describe it is a
cardboard "roof".  Picture the "eaves" running the legnth of the wall on
each side of it.  They can't jump up or they slide off... Good Luck!!!!
 
Also like to wish ALL a safe and happy New Year; prayers and thoughts w
ith NJ ferrets and all fuzzies everywhere....
