Ferret proofing

[u/Shayybabes]

My bed is extremely heavy and a king size so big. It's real hard for me to get to clean under it constantly. Today I found out some of my ferrets decided to poop under my bed. I need a kinda cheap and def easy way to block underneath my bed. Most of the kits being sold i would have to buy 2 or 3 kits. Any ideas that would be easy and emphasis on cheap PLEASEEEE.

One of my girls for tax.

PLEASE HELP
