What type of containers are best to store they hay and pellets in under the cage? In my new cage we are using the extra pieces to make storage but I need some sort of bins to keep it all organized I would love to be able to keep my hay and each pellets separate (I have some extra young piggie food from when they were younger). As well as separating treats and some interchangeable toys and housing maybe as well as the fleece bedding and pellets. You know all the stuff you need to put the cage together care for the piggies and some extras for them. Any ideas? A friend suggested just going to the container store and looking there for some different bins. She knows how organized I am when it comes to my girls.
