Months back I built a new cage for a pet supplies store's guinea pigs. They do not sell guinea pigs anymore but have five old boars that have been at the store all their lives. Most were born there and had never lived in any place but their small cages. I couldn't take it any longer and offered to build the cages if they paid for the coroplast, grids and wheels. I got the wood for free. It took me many weekends but to see the old guys run around and sort of popcorn it was well worth it. Since I took the pictures I built 2 duplex hidey houses so everyone has a place of their own. It has worked out well for everyone, the disabled girl that cleans the cages, the owner because the cages can be rolled and it's easier to clean under them, me because I'm given breaks on carefresh and the especially the piggies who now can run around and exercise. In a perfect world the cage would be bigger but it's so much better than the tiny cages they lived in for up to 6 years.
