I am a new cavy owner. I bought the biggest cage that the pet store had to offer. As soon as I assembled the cage, I knew that it would be a problem for many reasons. One problem is that it would be extremely difficult to clean. Another big problem is that it obviously was not going to be enough room for TWO sweet guinea pigs. So, I started doing research to find a better alternative for my cavy guys and stumbled upon a few fantastic sites about guinea pigs, which all lead me here. I just got the package of grids, connectors, etc., delivered on my doorstep today. I assembled it all in less than 20 minutes. I will be working on the upstairs "loft" portion tomorrow night. Pretzel and Mr. Nibbles LOVE their new "apartment". They immediately started running laps to check it all out. I already feel better just knowing that it will be so much easier to keep clean AND that my little cavy guys will be happier now that they have the living space they deserve.Special thanks to Sue for all that you do on behalf of the cavies and their families!
