The cage has lots of space & it's wonderful how you can connect the cages together & have multiple 'rooms'.  Also, the top coming completely off makes it very easy to interact with your pets.  Because it's light and easily portable a downside is created in that it is kind of flimsy.  May daughters only complaint is with the top because it can be cumbersome to get on & off.  Also, the pigs have started chewing through the liner after only a few weeks.
Easy cleaning tip - spread newpaper on the bottom and cover with an old towel.  The bottom has stayed clean except for around the edges.
