Don't do it. I adopted my pigs less than a week ago. I don't have very much room, and I opted for a 2x3 based on the "minimum square footage for two pigs" column on the site. Today I switched to fleece bedding with a "litter box" containing carefresh in the corner. My pigs have that, a hay rack, a water bottle and a pigloo that accomadates both pigs nicely. I also ordered a cozy cuddle cup from a lady, and I will need space for that. I have now realized that after I get the cozy cup, there really won't be much room for them to run around freely. I am feeling guilty, and I have decided to rack my brain for a some place to put their cage because now I understand that I must expand to a 2x4 if I ever want to see popcorning piggies. Too bad I wasted $15 on a piece of coroplast. Oh well, it's worth it for their happiness. I hope no one else makes the same mistake.
