Great horned owls can eat cats, but attacks on healthy adult house cats are not the owl’s main food source. These owls mostly hunt wild prey, yet they are powerful enough to kill small mammals and may target kittens, small cats, sick cats, or outdoor cats at night. Understanding when attacks happen, how much weight an owl can carry, and how to protect pets can help cat owners reduce the risk.

Do Great Horned Owls Eat Cats?
Yes, a great horned owl can eat a cat, especially if the cat is small, young, weak, or outdoors during hunting hours. However, cats are not a preferred everyday food. Great horned owls have a very wide diet that includes rodents, rabbits, skunks, birds, reptiles, amphibians, insects, and even other raptors. Cornell notes that this species has one of the most diverse diets among North American raptors.
A domestic cat may become prey when it is the right size and the owl has an easy chance to strike. Outdoor kittens are at the highest risk because they are light, inexperienced, and active near yards, trees, fences, and open spaces.
Can a Great Horned Owl Kill a Cat?
A great horned owl can kill a cat, but the risk depends on the cat’s size, health, and location. These owls are strong ambush predators. Cornell reports that a great horned owl’s clenched talons require about 28 pounds of force to open, and the bird uses that grip to subdue large prey.
Cats Most at Risk
- Kittens
- Small adult cats
- Elderly or sick cats
- Cats outside at night
- Cats near wooded edges, barns, rooftops, or open yards
- Cats left outside during nesting season
Large, healthy adult cats are harder targets. A great horned owl may still attack, but a full-grown cat can fight back with claws and teeth, making the encounter dangerous for both animals.
Can a Great Horned Owl Pick Up a Cat?
A great horned owl may be able to lift or drag a very small cat, but it usually cannot fly away with a normal-sized adult house cat. Great horned owls weigh about 32–88 ounces, or roughly 2–5.5 pounds, according to Audubon.
Cornell’s bird safety guidance says great horned owls can take prey over five pounds, which means kittens and very small cats are more vulnerable than heavier adult cats.
| Cat Size | Owl Risk Level | Why |
| Kitten under 5 lb | High | Easy to grab, lift, or kill |
| Small cat around 5–7 lb | Moderate to high | Possible target, especially at night |
| Average adult cat 8–12 lb | Lower, but not zero | Harder to carry, but can be injured |
| Large cat over 12 lb | Lower | Risk remains if the cat is weak or exposed |
When Do Great Horned Owls Attack Cats?
Great horned owls usually hunt at night, dawn, and dusk. They often perch quietly, watch for movement, then drop down suddenly on prey. The danger is higher in areas where owls nest or hunt regularly.
High-Risk Situations
- Letting cats outside after sunset
- Leaving pet food outside
- Allowing kittens to roam in the yard
- Living near woods, fields, parks, or farms
- Hearing regular owl hoots close to the house
- Seeing an owl perch on roofs, fences, or tall trees
Great horned owls are common across many habitats, including forests, deserts, suburbs, and city parks. Their ability to live near people is one reason cat owners sometimes report owl encounters near homes.
Great Horned Owl vs Cat: Who Would Win?
A great horned owl has the advantage in surprise, silence, flight, and talon strength. A cat has the advantage if it sees the owl early and can fight from the ground. In many cases, the owl’s success depends on the first strike.
A kitten or small cat may not survive an owl attack. A large adult cat may escape, but it can still suffer puncture wounds, eye injuries, broken bones, or deep infections. Even if the owl cannot carry the cat away, the attack can still be serious.
How to Protect Cats from Great Horned Owls
The safest choice is to keep cats indoors, especially at night. Outdoor cats face risks from owls, coyotes, dogs, cars, disease, and fights with other animals.
Best Safety Tips
- Keep cats inside from dusk until after sunrise.
- Use a catio or enclosed outdoor run.
- Supervise kittens outdoors.
- Remove outdoor food that attracts rodents and predators.
- Keep yards well-lit near doors and patios.
- Trim tall perches close to small pet areas when possible.
- Do not rely only on cat collars or bells.
A collar may help identify a pet, but it will not stop a great horned owl attack. If owls are active in your area, direct supervision and indoor housing are much safer.
What to Do If an Owl Attacks Your Cat
If your cat survives an owl attack, contact a veterinarian quickly. Owl talons can create small-looking punctures that hide deep tissue damage. Infection is also a serious concern.
Immediate Steps
- Bring the cat indoors.
- Keep the cat calm and warm.
- Do not wash deep puncture wounds aggressively.
- Call a veterinarian or emergency clinic.
- Report injured wildlife to a licensed wildlife rehabilitator if the owl is hurt.
Never try to trap, poison, shoot, or harm an owl. Great horned owls are native wild birds and are protected by law in the United States under the Migratory Bird Treaty Act.
FAQs
Do great horned owls hunt cats?
Great horned owls can hunt cats, but cats are not their main prey. They usually hunt wild animals such as rodents, rabbits, birds, and other small mammals. Outdoor kittens and small cats are more likely to be targeted than large, healthy adult cats.
Will a great horned owl attack a full-grown cat?
It can happen, but full-grown cats are harder and riskier prey. A great horned owl may attack if the cat is small, sick, unaware, or outside at night. Larger cats may escape, but they can still be badly injured by talons.
Can a great horned owl carry off a cat?
A great horned owl may carry off a kitten or very small cat, but most adult cats are too heavy to lift far. Even when an owl cannot fly away with a cat, it may still kill or injure it on the ground.
Are cats safe outside during the day?
Cats are safer during the day than at night, but not completely safe. Great horned owls are mostly nocturnal, yet they may be active at dawn, dusk, or near nesting areas. Supervised outdoor time is much safer than free roaming.
What scares great horned owls away from cats?
Bright lights, human activity, enclosed catios, and removing outdoor food can reduce owl visits. The best protection is keeping cats indoors at night. Noise devices or collars should not be used as the only safety method because owls may ignore them.
