The Richardson's Ground Squirrel is difficult to keep in captivity because of health problems associated with non-hibernation.
The Richardson's Ground Squirrel has a diet that consist of lots of grains, such as oats, wheat, barley, cereal, etc., seeds, and vegetarian products. Nuts, yogurt, or cottage cheese can be used as a nutritious treat a couple of times a week, but not too often as the animal's digestive tract can't handle an excess too well.
Your squirrel's housing should be quite tall and spacious. A three-story ferret cage is highly recommended with various climbing implements, a nesting box with nesting material, and a ferret exercise wheel.
This rodent can be trained to use a litter pan. One should be placed in a corner of its cage to reinforce its use.
This particular breed of squirrel is known to hibernate during the winter months.
No known vaccinations are required for the Richardson's Ground Squirrel, but a veterinarian knowledgeable in the health of squirrels should be sought out in case of emergencies.
