Whichever house structure you choose, it should have a wire mesh top, to prevent the gerbil from crawling out. Your gerbil's living environment should be lined with bedding or litter and cleaned twice weekly. The gerbil's space should be filled with toys and challenges to keep your pet active and stimulated. There are variety of rodent approved toys available commercially, like wheels, multi-level domes and bells. You can also use items from around the house to stimulate your pet.
Most rodents love tubes, in which they can run through and chew.
Paper towel or toilet paper rolls are favorite toys among many small rodents. Like many other domestic rodents, gerbils require bedding or litter. Avoid using pine and cedar wood shavings in the gerbil's cage, as the harmful oils of these substances are dangerous to most rodents. Appropriate bedding can include newspapers, rags, aspen chips, paper towels or shredded cardboard. Gerbils enjoy sunflower seeds, alfalfa pellets, vegetables and nuts.
