Yes, you can potty train a squirrel, but only partially and with significant limits
Squirrels can learn to use a litter box or designated toilet area, but they will never be reliably housetrained the way a cat or dog can be. A squirrel's instinct is to mark territory with urine and scatter droppings as it moves, and no amount of training fully overrides that behavior. What you can realistically achieve is teaching a captive squirrel to use a specific box for most of its waste most of the time—usually 60 to 80 percent success—which reduces but does not eliminate cleanup.
This matters because squirrels kept indoors (which is illegal in many states without a permit) will soil furniture, bedding, and walls if left unsupervised. A litter box gives you a contained spot to clean rather than searching your entire home. But expect accidents, especially during stress, illness, or when the squirrel is excited or playing.
Key Takeaways
- Squirrels can learn to use a litter box for the majority of their waste, but will still mark territory and have accidents unpredictably.
- Start training only after the squirrel is fully tame and comfortable in your space, which takes weeks or months of daily handling.
- Place a small litter box in the corner where the squirrel naturally goes most often, and clean it daily to reinforce the habit.
- Even successfully trained squirrels will soil bedding, nesting areas, and favorite perches, so plan for regular washing and spot-cleaning.
- Check your local wildlife laws before attempting to keep a squirrel indoors, as many states prohibit it or require a permit.
How squirrels naturally eliminate and why training is limited
Squirrels do not have the same bathroom instincts as domesticated animals. A cat naturally buries waste to hide its scent from predators—a behavior that translates well to a litter box. A squirrel, by contrast, marks territory by leaving urine and droppings in visible places, especially along branches, ledges, and the edges of its range. This is communication, not waste disposal.
Additionally, squirrels eliminate frequently throughout the day—often 10 to 15 times or more—and do not hold it the way a dog can. They may go while eating, playing, or moving between perches. This means even a well-trained squirrel will have accidents straightforward because it cannot always reach the box in time.
A young squirrel (under six months old) is more adaptable than an adult, but even young squirrels show territorial marking behavior as they mature. If you are considering this, start training as early as possible, ideally when the squirrel is still a juvenile.
Setting up a litter box and choosing the right location
Use a small litter box—a cat litter box is too large. A plastic storage container about 6 inches by 8 inches, with one side cut down to 3 inches high, works well. Fill it with aspen shavings, paper-based litter, or pine shavings (avoid cedar and clay litter, which are toxic to squirrels).
Place the box in the corner where your squirrel naturally goes most often. Watch the squirrel for a few days and note where it tends to eliminate. Most squirrels pick one or two preferred spots, usually in a corner away from their sleeping area. Put the box there, not where you want it—the squirrel's preference matters more than your convenience.
Keep the box clean. Scoop waste daily and change the litter every two to three days. A dirty box will be rejected, and the squirrel will find another spot. The goal is to make the box the most appealing toilet option in the space.
Training steps and what to expect in the first weeks
Start training only after your squirrel is fully comfortable with you and your home. A stressed or newly captured squirrel will not learn. This usually means waiting at least two to four weeks after the squirrel arrives, with daily handling and time in a confined space like a large cage or small room.
Once the squirrel is calm, place it in the litter box several times a day, especially after meals, after waking, and whenever you see it sniffing or circling (signs it needs to go). Do not force it—gently place it in and let it hop out. Reward it with a nut or treat if it stays in the box, even if it does not eliminate.
Watch for success. When the squirrel uses the box, do nothing—no praise, no fuss. Squirrels do not respond to verbal praise the way dogs do, and excitement can distract them. If you catch the squirrel eliminating outside the box, do not punish it. straightforward pick it up calmly and place it in the box. Punishment causes fear and makes training harder.
Expect the first two to four weeks to show little progress. By week four to six, you may see the squirrel using the box 30 to 50 percent of the time. By week eight to twelve, success rates often reach 60 to 80 percent. This is the realistic ceiling for most squirrels.
Why accidents happen and how to manage them
Even a well-trained squirrel will have accidents. Illness, stress, changes to the cage layout, a dirty litter box, or straightforward being too focused on play can cause the squirrel to eliminate elsewhere. During breeding season (late winter and spring), males especially will mark more aggressively, and training effectiveness drops.
Squirrels also soil their bedding and nesting materials deliberately—this is normal behavior, not a training failure. They mark their sleeping area as part of their territory. Wash bedding twice a week to manage odor. Use washable fleece or cotton blankets rather than absorbent materials that trap urine smell.
If accidents cluster in one spot, place a second small litter box there. Some squirrels do better with two or three boxes in different areas. If the squirrel stops using the box it was trained on, check that it is clean and in the same location. A moved box often gets ignored.
Odor control and keeping your space manageable
Squirrel urine has a strong, distinctive smell that builds up quickly. Even with a litter box, your space will develop an odor if the squirrel is indoors full-time. Wash all fabric surfaces weekly—blankets, cushions, hammocks, and nesting boxes. Use an enzymatic cleaner (the kind made for pet urine) on any spot where the squirrel has had an accident, because regular cleaners do not break down the urine compounds.
Ventilation helps. Keep windows open when weather allows, and consider a small air purifier with a HEPA filter. Do not use ammonia-based cleaners, which smell like urine to the squirrel and can trigger more marking in that spot.
If you are keeping the squirrel in a cage or enclosure, line the bottom with washable pads or towels rather than bedding that absorbs urine. Change these daily. A cage with a solid bottom is easier to manage than a wire floor, which allows urine to drip through.
Legal and health considerations before you start
Many states and municipalities prohibit keeping wild squirrels indoors without a permit. Some states allow it only if the squirrel was orphaned or injured and cannot be released. Check your local wildlife regulations before bringing a squirrel into your home—violations can result in fines or confiscation of the animal.
A squirrel kept indoors also needs veterinary care from a vet experienced with exotic animals, which is expensive and not always available. Squirrels can carry parasites and diseases, and they bite when frightened or during mating season. They are not domesticated, and their behavior remains unpredictable no matter how tame they seem.
If you find an orphaned or injured squirrel, contact a local wildlife rehabilitator rather than keeping it yourself. They have the informed, legal standing, and resources to care for it properly and release it when ready.
Frequently Asked Questions
Do male and female squirrels potty train differently?
Males are harder to train, especially during breeding season (late winter and early spring), because they mark territory more aggressively with urine. Females are slightly more consistent but still unreliable. Neither sex reaches the reliability of a housetrained cat or dog.
What if my squirrel refuses to use the litter box at all?
Move the box to where the squirrel is actually eliminating, not where you want it to go. Some squirrels also prefer a different litter material—try aspen shavings, paper pellets, or even soil. If the squirrel is very young (under three months), wait a few more weeks before trying again; very young squirrels are not ready to learn.
Can you potty train a wild squirrel you just caught?
No. A wild squirrel needs weeks to months to become tame enough to handle regularly. Training only works after the squirrel is fully comfortable with you and your space. A stressed or fearful squirrel will not learn and may bite.
Will my squirrel ever stop marking territory with urine?
No. Even a successfully trained squirrel will mark, especially during stress or breeding season. You can reduce the frequency and contain most waste to a litter box, but territorial marking is instinctive and cannot be eliminated through training.
Is it worth potty training a squirrel if it will still have accidents?
Yes, if you are committed to keeping a squirrel indoors. A litter box concentrates waste in one spot, which is far easier to manage than cleaning urine and droppings from furniture, bedding, and walls throughout your home. It reduces odor and makes daily care more practical, even if it is not a complete solution.
