Hi, I just set up a 4x2x2 zen habitat for my 7 month old. I put the basking spot I had been using previously in for now but it is hard to clean so I plan on replacing it and removing it. I just bought this what I think is a guinea pig house from pet valu. Just wanted an opinion on it before I open it and put a piece of tile on top. I would of course sand down any sharp or splintery spots.
