Flying Squirrel Ownership Checklist
| Do | Legal in your state (check fish & wildlife regulations) |
| Do | Tall enclosure (36–48 in min) with climbing surfaces |
| Do | 2 or more squirrels — never a single animal |
| Do | Willing to pouch-bond for 4–6 weeks |
| Do | Nocturnal lifestyle compatible with your sleep schedule |
| Do | Exotic vet with squirrel experience nearby |
| Avoid | Standard hamster cage — too short, wrong bar spacing |
| Avoid | Expecting a daytime cuddly pet |
Southern flying squirrels (Glaucomys volans) are legal to keep as pets in most US states and have a devoted hobbyist community. They are also nocturnal, require pouch bonding for 4 to 6 weeks before becoming handleable, need a cage tall enough for gliding, and thrive only in pairs or groups -- not as solitary animals. Most flying squirrel surrenders happen when owners realize the animal they expected is fundamentally nocturnal, not the semi-tame pocket pet the seller described. The species is genuinely rewarding when managed correctly.
Legality: check before acquiring
Flying squirrels are legal in most states but prohibited in California, Alabama, Hawaii, and a few others due to concerns about invasive species establishment. Some states require a permit. The Sugar Glider -- a marsupial unrelated to flying squirrels but often sold in similar contexts -- has separate regulations. Check your specific state fish and wildlife regulations before purchasing from any source.
The bonding process: pouch carry is not optional
Baby flying squirrels (joeys) must be bonded to their human owner through pouch carry -- keeping the young animal in a small bonding pouch worn against the body for several hours daily from the age of 6 to 8 weeks until approximately 10 to 12 weeks. During this period the animal imprints on the owner's scent and learns to associate human presence with safety rather than predator threat. Skip this step and the adult animal remains wild-defensive, biting reflexively at all human contact. The bonding window cannot be reopened in adults. Reputable breeders either complete early socialization themselves or provide detailed pouch-carry protocols to buyers.
Enclosure: height over floor space
Flying squirrels glide, not fly -- they extend skin membranes (patagia) between their front and back legs to control descent from height. To express this behavior they need vertical space. Minimum enclosure height for a pair is 36 inches; 48 inches is better. Width matters less than height. Bar spacing must not exceed 1/2 inch to prevent escape -- flying squirrels are extraordinarily nimble and will find any gap. Include multiple climbing surfaces, branches, hammocks, and a nest box or fleece sleeping pouch. Temperature should be maintained at 65 to 75 degrees Fahrenheit; flying squirrels may enter torpor below 60 degrees, which can be dangerous if mistaken for illness.
Diet in captivity
The TPG (The Pet Glider) diet developed for sugar gliders has been adapted for flying squirrels by the hobbyist community but is not a universally accepted standard. A broadly recognized functional diet for captive flying squirrels includes: high-quality seed mix (sunflower seeds limited to less than 10% due to fat content), hard-boiled egg or mealworms for protein (2 to 3 times weekly), fresh fruits and vegetables (40 to 50% of diet by volume), and a small amount of insect-based kibble. Wild flying squirrels are opportunistic omnivores eating nuts, seeds, fungi, insects, and small vertebrates. Calcium-to-phosphorus ratio matters: a diet heavily weighted toward seeds and fruit without calcium supplementation or variety leads to metabolic bone disease over time.
Health and veterinary access
Flying squirrels require an exotic vet comfortable with small mammals. In many rural areas, no such vet exists within reasonable distance -- confirming veterinary access should happen before acquisition, not after. Common health issues include metabolic bone disease (diet-related), obesity (excess seeds), and malocclusion (overgrown teeth from insufficient gnawing materials). Flying squirrels should have hard wood chews, natural branches, and nuts in shells available at all times to maintain incisor length. Body weight at health: 45 to 80 grams for Southern flying squirrels.
Social requirement: solitary housing causes welfare problems
Southern flying squirrels are colonial animals in the wild, sharing nests in groups of 2 to 20 individuals during winter. Solitary housing causes chronic stress, abnormal behavior (excessive bar-climbing, over-grooming), and shortened lifespan. Same-sex pairs or small groups are the minimum for welfare. Females can be housed together easily; males may fight unless raised together or introduced as juveniles. Introductions between adults require gradual scent-swapping over 2 to 3 weeks before shared housing.
