Hedgehog
Small Mammals
The spiky little explorer that runs on a wheel all night!
🤓 Did you know? When threatened, hedgehogs roll into a tight ball and can make a variety of cute snuffling and hissing sounds. They're surprisingly vocal!

🏠 Housing & Setup
Hedgehogs need more space than the small round cages commonly sold in pet stores. A minimum of 2 ft x 4 ft of floor space is required for one adult hedgehog, and more is always better. Excellent options include large plastic storage bins modified with ventilation, double-level Critter Nation cages with ramps (that the hedgehog can safely navigate), or DIY C&C cage setups.
Provide a solid exercise wheel 10 to 12 inches in diameter - this is not optional. Hedgehogs can run 5 to 8 miles per night on a wheel. A wheel that is too small (under 10 inches) causes spinal stress. The wheel must have a solid running surface, not bars or mesh, which catch legs and cause injuries. Carolina Storm Wheels and Bucket Wheel are widely recommended.
Temperature is critically important. Hedgehogs must be kept at 72 to 80 degrees F at all times. Below 65 degrees F, African pygmy hedgehogs (the common pet species) can enter a dangerous state of torpor - they are not cold-adapted hibernators, and torpor in pet hedgehogs causes organ damage and can be fatal. Keep the room warm and use a thermostat if necessary.
Bedding should be paper-based (Carefresh, shredded paper) or fleece liners. Never use cedar or pine shavings - the aromatic oils are toxic to small mammals. Provide a cozy hideout (a plastic igloo or small wooden hide box), a food dish, and a water bottle or heavy ceramic water bowl.
🥗 Diet & Feeding
High-quality cat food forms the cornerstone of most pet hedgehog diets. Choose a kibble with a named protein (chicken, turkey) as the first ingredient, low fat content (under 15%), high fiber, and no artificial colors or preservatives. Hedgehog-specific commercial diets exist but vary widely in quality - research ingredients carefully. A mix of 2 to 3 high-quality cat foods provides better nutritional variety than a single option.
Supplement with live insects 3 to 5 times per week. Mealworms (in moderation as they are high in fat and low in calcium), dubia roaches, crickets, and waxworms as an occasional treat are all appropriate. Insects provide protein variety and behavioral enrichment - hedgehogs actively hunt prey and this activity is enriching and natural.
Small amounts of cooked egg, plain cooked chicken, baby food (single-ingredient meat varieties), and low-fat cottage cheese can be offered occasionally for variety. Fresh fruits and vegetables can be offered in tiny quantities: blueberries, apple slices (no seeds), cooked carrot, and leafy greens are safe options. Avoid grapes, raisins, citrus, onion, garlic, and anything with xylitol.
Fresh water must always be available. Some hedgehogs prefer a water bowl over a bottle - offer both initially to see which the hedgehog uses more.
🎮 Enrichment & Handling
The solid exercise wheel is the single most critical enrichment item and must be provided every night. Without adequate running opportunities, hedgehogs become obese, lethargic, and develop behavioral and health problems. Most hedgehogs run for several hours each night. Accept that this is part of keeping a hedgehog and plan for the wheel noise accordingly.
Provide tunnels (toilet paper rolls, PVC pipes, plastic igloo tunnels), foraging toys (hiding insects or kibble in egg cartons or puzzle feeders), and safe items to explore at various heights. Hedgehogs have excellent senses of smell and will investigate every new scent in their environment. Rotate enrichment items regularly.
Supervised free-roam time in a warm, hedgehog-proofed area (no gaps under furniture large enough for escape, no electrical cords at floor level) is excellent additional enrichment. Many hedgehogs enjoy bath time in a shallow, warm water tub and will swim briefly before toweling off.
Most hedgehogs have a grumpy, defensive reputation - but with patient, consistent handling from a young age, many become quite relaxed and even sociable. Handle at dusk when they are naturally active. Move slowly, support the whole body, and avoid startling them. An anointing hedgehog (self-anointing with unusual scents by licking and spreading saliva on their quills) is engaging and completely normal behavior.
💊 Health & Common Issues
Wobbly Hedgehog Syndrome (WHS) is a progressive and incurable neurological disease caused by a genetic mutation that causes muscle wasting and progressive paralysis, starting in the hindquarters and moving forward. It affects an estimated 1 in 3 African pygmy hedgehogs and has no treatment. A hedgehog with WHS will gradually lose the ability to use its hind legs, then its front legs, and eventually lose the ability to eat. Comfort care and quality of life management with veterinary guidance is the approach.
Obesity is extremely common and leads to fatty liver disease, heart problems, and joint issues. Hedgehogs become obese from overfeeding high-fat insects, insufficient exercise, or inadequate wheel access. Monitor body condition: you should be able to feel but not see the hip bones. A hedgehog that cannot curl into a full ball due to fat deposits is significantly overweight.
Cancer is unfortunately common in hedgehogs over 3 years old - tumors of the uterus, mouth, and mammary glands are most frequently encountered. Annual veterinary examinations with an exotic vet experienced in hedgehogs are strongly recommended from age 2 onward. Spaying females reduces uterine cancer risk significantly.
Torpor (temperature-induced dormancy) in response to cold temperatures is a veterinary emergency in pet hedgehogs. Signs include extreme lethargy, cold body temperature, and difficulty moving. Warm the hedgehog slowly against your body and contact a vet immediately.

❓ Frequently Asked Questions
Are hedgehogs nocturnal?
Yes. African pygmy hedgehogs - the standard pet species - are crepuscular to nocturnal, most active from dusk through the night. During daylight hours they will typically sleep in their hideout or curl into a defensive ball. The best time to interact, feed, and observe your hedgehog is in the evening and early night hours. Forcing interaction during the day causes significant stress. If you are primarily a daytime person, a hedgehog's natural schedule may not align well with your lifestyle.
Can hedgehogs run on a wheel?
Yes - and they must. A solid exercise wheel 10 to 12 inches in diameter is one of the most critical pieces of hedgehog equipment. Hedgehogs can run 5 to 8 miles per night and require this nightly exercise for physical and mental health. Without adequate wheel access, hedgehogs become obese, lethargic, and develop health problems including fatty liver disease. The wheel must have a solid running surface - bars or mesh injure feet and legs.
What do hedgehogs eat?
High-quality low-fat cat food forms the backbone of most hedgehog diets. Look for a named protein (chicken, turkey) as the first ingredient and fat content under 15%. Supplement with live insects 3 to 5 times per week - dubia roaches, small mealworms in moderation, and crickets are appropriate. Small amounts of cooked egg, cooked chicken, and safe fruits and vegetables like blueberries, apple, and cooked carrot can be offered as variety. Avoid grapes, raisins, avocado, citrus, onion, garlic, and any xylitol-containing foods.
What is Wobbly Hedgehog Syndrome?
Wobbly Hedgehog Syndrome (WHS) is a progressive, incurable neurological disease caused by a genetic mutation that produces muscle wasting and paralysis. It begins in the hindquarters and moves forward over months to years, eventually affecting the entire body. An estimated 1 in 3 African pygmy hedgehogs is affected. There is no treatment - management focuses on quality of life with veterinary guidance on when euthanasia becomes the compassionate choice.
How long do hedgehogs live?
African pygmy hedgehogs typically live 3 to 6 years in captivity. Some individuals reach 7 to 8 years, but this is the exception. Lifespan is significantly affected by genetics (WHS, cancer predisposition), diet (obesity is extremely common and life-shortening), and access to appropriate veterinary care. Annual check-ups with an exotic vet experienced in hedgehogs from age 2 onward are strongly recommended.

🤩 Fun Facts
🦔 Spiny Situation
Hedgehogs have between 5,000 and 7,000 spines on their back! Each spine lasts about a year before it falls out and a new one grows in its place. Baby hedgehogs are born with their spines just below the skin.
🦔 Cuddle Drones
Hedgehogs can run at speeds up to 6 miles per hour, which is quite fast for such small creatures! But don't be fooled by their spiny exterior; they love to curl up into little balls for cuddles when they're feeling safe.
