This cage really is perfect for guinea pigs. It takes less than 5 minutes to clean, scooping out the litter in the toilet area and replacing with fresh, and then sweeping and wiping down the play site with a damp rag soaked in a vinegar/water solution or very dilute bleach solution. I only wish that the recycled paper-based litter was less expensive; we're using the much more affordable pine litter, which gets kicked out onto the floor and sticks to their feet, getting tracked out into the play area. We're planning to create a screen frame around the cage, which will come up higher than the bottom panel, to prevent the litter from getting kicked out. Other than that, however, the cage is really a great size for two guinea pigs.
