So I've been thinking about switching to all out racks for my ASFs... I've tried a rack a couple times with no success due to chewing, so I was trying to think of a cheap/fool proof tub for ASFs. My question is would sheet metal work? If I folded sheet metal into a tub looking style and welded it would that work? Or would there be a negative effect on the metal due to the urine? Any input or thoughts or advice is always welcomed and loved.
