It was being stripped about every 3 days or so, and new bedding added the days in between.
We decided to add some stuff called Sweet PDZ to her stall under the bedding. It is pretty much like cat litter, supposed to absorb. It has made a HUGE difference in how long her stall stays clean, and we only add half a bag per strip.
For other people with piggies like mine, I recommend giving it a shot!
