So you used some sheet linoleum to make the cage bottom? How did you secure it in the corners? Did you have problems with pigs chewing on it? How often do you have to clean it? Does the linoleum absorb much odor (as some plastics can do...) What type litte are you using? Hmmm... we have some spare congoleum from our kitchen floor downstairs in the basement. Now if I can just find those stinkin' cage squares I'd be in business.
FYI -- we have 2 pigloos too, one smooth dome, one castle! The castle one is fun to play "King of the Pigloo" on, I guess!
you should definitely try to go the fleece route, it's so much easier to clean and you save a butt load of cash on not buying that much bedding! great cage
