I am 11 years old, I got 2 degus from a friend. Dad built me a cage, pretty big one, I think 1.5 feet square and 3 ft high. They like it a lot. The were in a large birdcage before, but it was to small and they like to climb and run. So we put a bunch of tree branches in it, so they can climb. We feed them rabbit pellets, and fresh grass, and always lots of water, we have that in one of them bottles with the metal spout. We also have a ball that they can run around the room in, when they need excercise. It is fun. we also give them alfalfa, and Dad built them a house to sleep in. There is clumping cat litter in a bread pan, and they like to have a dust bath in it. The also use it for the bathroom but I don't like that much. I also like to give them apple, and fresh leafs from the trees.
