WE Love our fuzzy floors. Over the last few years our shelter aquired several of the older midwest playpen cages-- now, they are large... but, not really safe or ferret friendly in my opinion. so, they were not much use to us. Thanks to Karen and 6 sets of of Fuzzy floors ...not only were these cages made safe -- but we were able to increase the usable area of each cage by at least 3x's -- the ferrets LOVE the floors and although we had several that got lazy and prefered to poop on the fabric floors instead of traveling to their litter box - the cleanup was really quite easy-- they remove easy, wash in a standard washing machine and fit right back in.. no problem. We have had a problem with the single pocket model a couple times-- some of our larger ferrets ( personally, I think they were either a bit "slow" or lazy) couldn't figure out how to get to the other levels -- but they had no issues with the basement or the simple direct floor with the straight through holes-- We have given away a few of these cages when we have been lucky enough to find a perfect adopter willing to take a whole group of bonded ferrets-- and the new families also, LOVE the floors. We are in the process of converting over to all FN cages and hope to purchase full sets of fuzzy floors for these cages as well.. The fuzzies at Wind & Willows Ferret Rescue in Fallon, NV and their "mom" highly recommend the fuzzy floors especially the basement models. Karen put a great deal of thought and effort into the design, safety and functionallity of thses floors-- no other product on the market comes even close.
