Found this 110 qt (27.5 gal) bin at Big Lots for $15. I had the hardware cloth, so I bought $11 worth of nuts, bolts and washers. For $26 out of pocket and about an hours worth of my time, I have large, lightweight cage.
I just love these things. I may make another smaller one out of tub I saw at Home Depot for $5. Don’t have anything planned for a smaller one, I just love to make them and love the way they look LOL.
This one is just waiting for 2 or 3 Gerbils. They will have plenty of room to run around and dig and chew lots of cardboard.
