If you’ve ever considered adopting a squirrel, rescuing one, or simply wondered about their potential lifespan in a protected environment, you’ve likely asked: how long do squirrels live in captivity? The answer may surprise you — when given the right nutrition, shelter, and medical care, captive squirrels can live significantly longer than their wild counterparts.
In this in-depth guide, we’ll explore the average lifespan of captive squirrels, how various factors influence their longevity, and how to create the ideal environment for pet or rescued squirrels to thrive.
Average Lifespan of Squirrels in Captivity
Squirrels living in captivity typically live between 10 to 20 years, depending on their species, care level, and living conditions. This lifespan far exceeds that of wild squirrels, who face daily threats from predators, harsh weather, disease, and traffic accidents, limiting them to an average lifespan of just 3 to 6 years. Read more about how long squirrels live in the wild and what factors affect their survival.
Lifespan by Squirrel Species
1. Gray Squirrels (Sciurus carolinensis)
- Captive Lifespan: 15–20 years
Gray squirrels are one of the most adaptable species, making them ideal for captivity under proper care. They respond well to routine and human interaction.
2. Flying Squirrels (Glaucomys spp.)
- Captive Lifespan: 10–15 years
Flying squirrels are nocturnal and emotionally sensitive. They require calm environments, gentle handling, and enrichment to avoid depression or stress. You can learn more about how long flying squirrels live and how to care for them properly.
3. Red Squirrels (Tamiasciurus hudsonicus)
- Captive Lifespan: 8–12 years
Territorial by nature, red squirrels need larger enclosures with vertical climbing space and mental stimulation to prevent aggression.
4. Fox Squirrels (Sciurus niger)
- Captive Lifespan: 12–18 years
Fox squirrels are known for their docile behavior and make relatively easier captive companions, especially if socialized early.
Why Do Squirrels Live Longer in Captivity?
Captivity eliminates many dangers faced in the wild. The following factors contribute significantly to their longer lifespan:
✅ Protection from Predators
Captive squirrels aren’t exposed to natural predators like owls, hawks, snakes, and coyotes.
✅ Balanced Diet
Regular access to calcium-rich foods, fruits, vegetables, and clean water promotes skeletal and metabolic health.
✅ Veterinary Support
Access to exotic animal veterinarians means early diagnosis of illnesses like metabolic bone disease or infections.
✅ Stable Environment
Controlled indoor environments reduce exposure to extreme cold, heat, and nest flooding — all of which can be fatal to wild squirrels.
Nutrition & Enclosure: Key to Longevity
A well-fed and well-housed squirrel is a healthy squirrel. Here’s how to extend the life of your pet or rescued squirrel:
🍎 Recommended Diet
- Fruits: Apples, bananas, grapes
- Vegetables: Carrots, kale, broccoli
- Nuts: Walnuts, hazelnuts (in moderation)
- Extras: Yogurt (calcium), occasional boiled eggs
❌ Avoid: Sunflower seeds, corn, and peanuts in excess — they are high in phosphorus and low in calcium, leading to imbalances.
🏡 Ideal Habitat Setup
- Cage Type: Large, vertical cages with metal bars
- Add-ons: Wooden branches, hanging ropes, nesting boxes, soft bedding
- Space Requirement: Minimum of 3 feet tall with horizontal and vertical play zones
🧠 Enrichment Tips
Squirrels are intelligent and curious animals. Lack of stimulation can lead to destructive behavior and stress.
- Provide toys, foraging puzzles, and rotating enrichment activities.
- Allow daily out-of-cage time (supervised) in a secure area.
🛠️ Tip: Change toys weekly to prevent boredom.
Baby Squirrel Care in Captivity
Rescuing a baby squirrel (also called a “kit” or “pup”) requires specialized care, especially in the first few weeks.
- 0–5 Weeks: Needs formula feeding every 3–4 hours and constant warmth
- 6–10 Weeks: Weaning onto soft solids begins
- 11+ Weeks: Can be moved to a large cage with enrichment
Warmth, cleanliness, and consistency are vital at this stage. Improper care can result in developmental delays or early death.

Captive Squirrel Ownership: Pros and Cons
While a long lifespan is a benefit, owning or caring for a captive squirrel also has its challenges.
⚠️ Legal Restrictions
In many states or countries, it is illegal to keep a squirrel without a license or permit. Check with local wildlife authorities before adopting.
⚠️ High Activity Needs
Squirrels need daily stimulation, space, and mental engagement. They’re not suited for small cages or inactive households.
⚠️ Behavioral Issues
Biting, furniture chewing, and stress-induced illnesses can occur if not socialized properly from a young age.
⚠️ Emotional Sensitivity
Squirrels form strong bonds and may suffer from separation anxiety or depression if left alone too long.
🌍 Geographic Impact on Squirrel Lifespan
Climate and environment also play a critical role in a squirrel’s lifespan in captivity:
Location | Average Captive Lifespan | Notes |
| Texas | 15–20 years | Warm climate supports year-round comfort |
| Florida | Up to 20 years | Excellent for squirrel health due to humidity control |
| Canada | 10–15 years | Indoor heating essential in winter |
Ensure temperature and humidity levels are squirrel-friendly wherever you live.
importance of Exotic Veterinary Care
Don’t underestimate the importance of professional help. Annual checkups, parasite control, and emergency visits can prevent premature death. Look for:
- Exotic pet specialists
- Experience with rodents or small mammals
- Clinics with 24-hour emergency care
🚨 Common health risks: dental overgrowth, bone disease, pneumonia, mites
