Purchased the medium cage stand and it is great. Makes cleaning easier, no more kneeling or achy backs !
Kids like how they can stand and play / feed the guinea's too. My only down side is it is a little shaky. One of our piggies likes to do 'laps' around their cage at 11pm at it does cause the cage to shake, which it didnt do on the floor obviously. It's not a bad thing, just may give the piggies a strange sensation.
