Midwest Homes (brand) Guinea Pig Habitat. Size: 47”L x 24”W x 14”H (7.8 sq ft) We used this home for our 2 guinea pigs and it was great! They had plenty of room. … We also bought a modification kit to add a “Loft” (second story) which gave them even more room to fun around.… The Loft swings up for easy cleaning (see 3rd photo) and is attached with a series of zip-ties so it can be easily removed if you do not want to use it. The cage also comes with a top - although it doesn’t fit if the Loft is being used. There is also a “divider panel that you can use to split the cage into 2 sections (see Amazon photo) - although we never used it. This item is “gently used” but still in excellent condition. It was kept in a smoke-free home.
