Review on Breathable & Transparent Small Animal C&C Cage Tent: Pop-Up Portable Exercise Fence For Guinea Pigs, Rabbits, Hamsters, Chinchillas, And Hedgehogs - Ideal For Both Indoor And Outdoor Use (Green) by Renee Hackbarth

I had this cage for my guinea pig because I liked the shape versus the more usual rectangle shape. I found this cage super easy to set up, use, and especially easy to clean. Once I needed to clean the cage, I could easily remove my guinea pig and shake out the toys, houses, and fleeces and lift the cage to collect all the waste into one area and empty it. HOWEVER, after about 8 months, my guinea pig learned how to escape by pulling down the edge of the cage and stepping over, so I had to move him to a more standard metal cage.
