I own a total of 3 of these cages now. A great alternative to a C&C cage for a guinea pig. One cage has plenty of space for a large guinea pig or two small ones. The cages line well with towels and fleece [my choice bedding for guinea pigs].

A downside I've found is that one of my guinea pigs finds the canvas edging on the sides of the base to be a very yummy treat.
