His cage is two grids wide, two grids tall, and three grids long. There are currently two levels on it. I don't have pictures yet, I will post some once he's been able to settle in some. I put a shower curtain over my floor, with a rug over top. I'm going to leave it there unless he decides to chew, then I'll flip it over and see how he does then. I have a base for a store cage as his litter pan, and he's so tiny that he fits along with his pellets, veggie dish, and hay! My one guinea pig weighs more than him I'm pretty sure. He will be free range when we are home. He hasn't really done much besides give me some cuddles, and ate some hay. I hear him hop every once in awhile, but not much lol. Hopefully he likes his cage, it's got to be better than the wire bottom cage he's been in.
