It actually worked out perfectly with Mr Bubbles on the bottom and Scruffy on the top. Scruffy loves to sit up and survey the room while Mr Bubbles prefers a little more privacy. It's funny because out of the 4 guinea pigs, Scruffy is the only one who can leap onto the built in platform. The other 3 are too fat to jump up. I'm going to have to make ramps for the others LOL! They all love the shelter provided by the under part of the platform. I should have done this long ago.
