How to Protect Flying Squirrels From Outdoor Cats at Night

Flying squirrels are most at risk where their nighttime routes bring them close to cats: around tree trunks, feeders, decks, fences, and other places cats can wait in cover. The most reliable way to prevent encounters is to keep pet cats indoors after dark, or provide outdoor access only in a secure enclosure. Homeowners can also reduce ambush points and make food and nesting areas less accessible to cats.

Flying squirrels are small, nocturnal rodents that glide between trees using a membrane of skin stretched between their limbs. They do not fly under their own power. Their nighttime habits can make them hard to see, but a few clues may reveal that they visit a yard.

Recognizing flying squirrel activity

Flying squirrels are usually active after sunset. You may spot large, reflective eyes in a flashlight beam, hear soft chirps or squeaks, or see an animal glide between trees. Their movements can be mistaken for those of other small mammals, so a single glimpse may not be enough to identify one with confidence.

Other signs include:

• Small tracks or droppings near a tree cavity, nest box, or feeding area
• Nuts or seeds with gnaw marks
• Repeated nighttime activity captured by a motion-activated camera
• Visits to bird feeders, especially after dark

These signs do not prove that flying squirrels are present. Other rodents also eat seeds and leave similar traces. A camera aimed at a feeder or a likely travel route can help confirm activity without disturbing wildlife.

Flying squirrels use tree cavities and other sheltered spaces for nesting and resting. They may travel between trees by gliding, and can also climb trunks and branches. A yard with mature trees, connected canopy, and nearby food sources may be part of their range even if you rarely see the animals.

Why cats pose a risk

Cats are skilled hunters and may stalk wildlife even when they are well fed. A cat can catch an animal before a homeowner notices it, particularly in low light or in a yard with shrubs, woodpiles, or other cover. Flying squirrels’ nocturnal activity brings them into the same hours when many cats roam outdoors.

Gliding helps flying squirrels move between trees, but it does not make them safe from ground-level or climbing predators. A squirrel may descend a trunk, land near a cat, or cross a short gap where a cat is waiting. Cats can also climb trees and reach low branches or cavities.

A cat’s presence can create risks beyond a direct attack. Repeated stalking may disturb animals near nesting or feeding sites, and cats may catch other nocturnal wildlife in the same areas. Reducing outdoor cat access protects more than flying squirrels.

Find the places where an encounter could happen

Look at the yard after dark, or review footage from a motion-activated camera. Pay attention to places where a cat can hide and where a squirrel might land or pause:

• The base of trees with cavities or nest boxes
• Shrubs or dense ground cover beneath branches
• Fences, decks, sheds, and woodpiles near trees
• Feeders, spilled seed, compost, or other food sources
• Narrow passages between a house, fence, and vegetation

A cat may use the same route repeatedly, especially along fences or through sheltered edges of a yard. If you see a cat waiting beneath a tree or feeder, that spot deserves attention. Do not assume every squirrel route can be redirected safely; flying squirrels need access to trees and shelter, and broad changes to the habitat can cause other problems.

Reduce the chance of predation

Keep pet cats indoors at night

Keeping cats indoors is the most dependable way to stop them from hunting wildlife in your yard. Indoor-only living also reduces the risks cats face from traffic, fights, and disease. If your cat is accustomed to going out, establish a predictable evening routine and offer indoor play, climbing space, and resting places.

If a cat needs outdoor time, provide it under supervision or in a secure catio. The enclosure should have a roof and secure sides, with no gaps a cat can squeeze through or climb over. Place it away from trees, fences, and roof edges that could provide a route out. A catio gives a cat access to fresh air while preventing it from roaming freely.

A bell or brightly colored collar attachment may reduce some hunting success, but neither is a substitute for keeping a cat contained. Cats can still catch wildlife, and collars can snag if they are not designed with a quick-release feature.

Limit nighttime access

If full-time indoor living is not practical immediately, bring cats inside before dusk and keep them in until morning. Flying squirrels are nocturnal, so restricting access during nighttime hours can substantially reduce overlap. A cat door that allows free outdoor access defeats this measure; use a lockable door or another way to prevent unsupervised exits.

Let neighbors know if their cats regularly enter your yard. A calm conversation may help, especially if you can point to a specific tree, feeder, or nesting area where cats have been seen. Avoid trapping or relocating someone else’s cat. Local animal-control agencies or humane organizations can explain appropriate options.

Manage feeders and other food sources

Bird feeders can attract rodents, including flying squirrels, and spilled seed can draw them to the ground. If you keep feeders, use catch trays, clean up fallen seed, and avoid placing feeders beside dense shrubs or low branches where a cat can hide. Bring feeders in at night when practical, especially if they are attracting animals to a known cat route.

Do not put out food specifically to lure flying squirrels closer. Concentrating wildlife around a feeder can increase contact with cats and other hazards. A wildlife-friendly yard can provide natural food and shelter without turning one small area into a predictable gathering point.

Keep routes and nesting areas safer

Trim branches that touch buildings or provide direct access to a catio, porch, or other enclosed area. This can help contain a pet, but avoid cutting trees simply to prevent flying squirrels from moving through the yard. Their gliding routes and tree connections are part of their habitat.

Keep shrubs and stored materials from forming concealed ambush spots directly beneath known nesting trees. The goal is not to strip the yard of cover, which wildlife also needs, but to avoid creating a hidden waiting place beside a high-use landing area. If you maintain a nest box, place it where cats cannot readily reach it and follow guidance from a local wildlife agency or experienced nest-box program. Do not handle or inspect a box during the nesting season unless you have a specific, safe reason and know local rules.

If a cat brings home a flying squirrel

Treat any squirrel caught by a cat as an urgent wildlife case, even if it appears alert and has no visible wound. Cat teeth can leave tiny punctures that are difficult to see. Bacteria from a bite or scratch can cause a serious infection, and an animal may be in shock or have internal injuries.

If the squirrel is alive:

1. Keep people and pets away, and do not let the cat continue handling it.
2. Wear gloves if you must move the animal. Use a towel to place it gently in a small, ventilated box lined with a soft cloth.
3. Keep the box dark, quiet, and at a comfortable room temperature. Do not give food, water, or medication.
4. Contact a licensed wildlife rehabilitator promptly and follow their instructions.

Do not try to treat wounds or release the squirrel based only on its apparent condition. A wildlife rehabilitator can assess injuries and determine whether treatment is possible. In many places, wildlife care requires a permit, so an untrained person should not attempt to raise or treat the animal.

If you cannot reach a rehabilitator, contact a veterinarian, animal-control agency, or state or provincial wildlife office for local guidance. Do not leave an injured squirrel outside in the hope that it will recover on its own.

A safer yard starts with containment

The clearest way to protect flying squirrels from outdoor cats is to prevent cats from roaming, especially at night. Secure enclosures and supervised outdoor time let cats experience the outdoors without exposing wildlife to a free-ranging hunter. Thoughtful feeder placement, attention to ambush spots, and prompt help for any cat-caught animal can further reduce harm while preserving the trees and shelter that make a yard useful to nocturnal wildlife.
