There is no best guinea pig cage for all cavies or all pet parents. However, there are several good guidelines to follow when choosing one. The most important guideline is to invest in large guinea pig cages that provide enough space for your guinea pig to move, play and exercise.
Guinea pigs are one of the largest animals of the rodent family and they need room to stretch their legs. If their habitat is too small, your cavie could grow bored or depressed and may even develop certain health conditions—including heart disease, diabetes or bumblefoot. A habitat for a single guinea pig should be a minimum of 7.5 square feet. Two guinea pigs should ideally have 10.5 square feet of habitat space. The size of the habitat should increase for each additional guinea pig you add.
A good guinea pig cage will also include enough space to create different areas within the habitat. Guinea pigs usually do best when they have separate spaces for nesting, playing and eating, as well as a separate bathroom area.
Additionally, make sure the habitat offers good ventilation. Choose a habitat with a wire bar top. If you don’t have other pets that could consider your guinea pigs to be prey, you can even have an open-top habitat—as long as the bottom is deep enough.
To make life easier for you, consider selecting a guinea pig habitat with water-proof flooring. Many habitats also include easily detachable tops which can make cleaning the habitat and interacting with your pet easier.
Finally, glass aquariums and plastic tubs are not considered an appropriate habitat for guinea pigs. You’ll also want avoid guinea pig habitats with wire flooring. Your cavie’s small feet could get stuck between the bars, injuring your pet’s leg.
