Guinea Pig Cage Requirements

Guinea pigs (or cavies) make great pets because they are affectionate, colorful and make pleasing noises. They make great pets for children as well as senior citizens. But there are many cages sold as being suitable for guinea pigs that really aren't. Although they are rodents, guinea pigs have different housing needs than hamsters, rats or gerbils.

  1. Indoors

    • Up until the 1970s, it was common to keep guinea pigs outdoors in rabbit hutches. However, guinea pigs are very sensitive to weather changes and are defenseless against predators like feral cats, so keep them indoors.

    Solid Floors

    • Guinea pigs cannot live in cages with wire mesh floors. Because their feet are so small, they can slip through the mesh and break.

    Ventilation

    • Guinea pigs thrive best in cages with a barred wire lid or side door. Aquariums are not recommended, as they heat up inside too fast and trap ammonia fumes.

    Size

    • According to the Humane Society of the United States (HSUS), the smallest cage for one guinea pig should be 18 inches wide, 14 inches high and 25 inches deep, or roughly seven square feet. If two guinea pigs are kept, another two to four square feet need to be added (see Resources).

    The Ideal Cage

    • An ideal cage is one with a solid tough plastic bottom and a top half made of metal bars. This is easy to clean, as well.
