What is the history of Richardson's Ground Squirrel?
Richardson's ground squirrel was discovered in 1820 by the naturalist John Richardson. It resembles a small prairie dog. The exact date of its first existence is unknown. Following the ban on importing popular prairie dogs in 2003, Richardson's ground squirrels, which look similar, started gaining attention and have since been imported to Japan.
What is the character of Richardson's Ground Squirrel?
These animals typically prefer solitary activities rather than forming family groups. They spend about half of the year hibernating, which might suggest they have an indoor-type personality. They are vigilant and timid, so it may take some time for them to get comfortable if adopted as pets. Carefully and patiently building a bond with them is essential.
Richardson's Ground Squirrel Q&A
What is the origin of the name 'Richardson's Ground Squirrel'?
'Richardson' is named after the discoverer, the naturalist John Richardson. 'Ground Squirrel' translates in Japanese to '地栗鼠 (jirisu),' meaning 'ground squirrel,' reflecting its habitat on the ground. The name combines these elements. Due to its resemblance to the prairie dog, it is sometimes referred to as 'mini prairie dog.' It is also called 'flickertail' because it flicks its tail when alarmed.
Why does Richardson's Ground Squirrel live there?
Richardson's ground squirrels inhabit grasslands and hilly areas primarily in Canada and the northern USA. The reasons are unclear, but since they dig burrows to live in, grasslands and other soft-soiled areas are likely favorable due to ease of digging.
What does Richardson's Ground Squirrel eat?
Being herbivores, they commonly eat grasses such as Timothy hay. In the wild, they may also consume fruits, nuts, and insects. Like other rodents, they have cheek pouches to store food, which they fill to the brim. When eating, they hold food with both hands, which looks very charming. For pet squirrels, a mixed diet similar to that for prairie dogs or rabbits is recommended. Treats can include vegetables and fruits prepared for small pets, but care must be taken with high-calorie foods like sunflower seeds and nuts due to their propensity to gain weight.
What is the breeding season like for Richardson's Ground Squirrel?
Males and females are capable of breeding at one year of age. They breed once a year, producing 3-11 pups per litter, though there is individual variation. Most young are weaned by about one month of age.
What diseases are Richardson's Ground Squirrels susceptible to?
They can suffer from sinusitis due to their nasal breathing which can lead to nasal discharge and inflammation that may block their airways. Skin diseases caused by bacterial infections can result in itching, dandruff, and hair loss, and tumors may also develop. Obesity can occur under captivity conditions without hibernation, due to overfeeding and lack of exercise. It is crucial to notice small changes in their health as small animals often hide their ailments. Weight tends to decrease during the mating season, so careful observation is particularly important then.
What should be considered when adopting Richardson's Ground Squirrel as a pet?
Due to their propensity to gain weight, diet and exercise are crucial. Provide gnawing toys like those for rabbits or prairie dogs, exercise wheels, sand baths, hay feeders, and water dispensers. Rabbit-sized cages and toilets are suitable as there are no specific ones for Richardson's ground squirrels. Ensure a comfortable environment with room temperatures between 18-25 degrees Celsius. In winter, a small animal heater is necessary to prevent cold stress.
How does Richardson's Ground Squirrel vocalize?
They typically make 'pee' or 'kyu' sounds, but generally, they are not very vocal unless alarmed or during mating season. Some individuals may vocalize when seeking attention from their owners.
How to differentiate between Richardson's Ground Squirrel and Prairie Dogs?
Richardson's ground squirrels are generally smaller than prairie dogs. Thinking of them as 'mini prairie dogs' can help in distinguishing them.
