All 3 of my pigs like to poop when they're eating. So, I decided to put their food in a box, and everytime I clean the cage, I get a new box for it. So it's about twice a week. This way it helps from staining the blankets, or leaking through to the floor. Just keeps things a little tidier for them. I have a cheap blue organizing bin that I got at the dollar store right next to the box because sometimes they go in there. I put Aspen shavings in there, so it's like a comfy litter box.
