Sexing and Reproduction:

  • Males have a large, dark scrotum and a longer anogenital distance than females.
  • Breeding pairs tend to be monogamous and maintain lifelong relationships.
  • Gerbils should be introduced before they are 8 weeks of age to reduce the risk of fighting. Adult gerbils of either sex may fight to the death if introduced as adults.
  • Neutering the male can prevent overpopulation.


  • Gerbils are social animals and are best housed in pairs.
  • The minimum cage size should be 36 square inches per gerbil; a pair requires a minimum of 180 square inches.
  • The enclosure should be escape proof with a secure lid.
  • The enclosure should be cleaned thoroughly at least weekly to reduce odors. Remove wet spots daily.
  • Ideal environmental temperature is 60-70 degrees F (16-21 degrees C).
  • Ideal relative humidity should not exceed 30-50%.
  • Exercise wheels and plastic exercise balls provide an outlet for energy.
  • Gerbils like to build nests out of nesting material.


  • Commercial pellet diets are available for gerbils.
  • Alfalfa hay should be available for grazing and is a good calcium source for nursing females.
  • Excessive consumption of sunflower seeds and other high-fat foods will lead to obesity.
  • Provide fresh drinking water via a sipper tube.

Grooming and Hygiene:

  • Gerbils stay clean and rarely need baths.
  • Consult with a veterinarian if your gerbil’s teeth or nails seem too long.
  • Because all gerbils are potential carriers of infectious diseases, always wash your hands before and after handling your gerbils and/or habitat contents to help prevent the potential spread of diseases.
  • Pregnant women and people with weakened immune systems should contact their physician before purchasing and/or caring for a gerbil.

Extra Tip:

  • May be helpful to purchase a gram scale to keep track of your gerbilr’s weight and food consumption.
