Rat predators do more than thin out rodent numbers in a backyard or barn — they act as a biological shield against disease, since rat predators act as a biological shield for human health, keeping populations low enough to prevent the spread of Leptospirosis and Hantavirus. Animals that eat rats come from nearly every branch of the animal kingdom, from house cats and barn owls to constrictors that swallow their prey whole. Each predator has evolved its own toolkit — talons, venom, night vision, or raw persistence — to turn a rat into a meal.
This rundown covers 26 species that regularly hunt or scavenge rats, organized by the hunting style each one relies on. Predation is only one part of the story, too; the same survival pressure that drives a hawk to stoop on a rat also explains stranger behaviors elsewhere in nature, including cases where animals eat their own mates when food or reproductive stakes run high. The throughline is the same: survival rarely leaves room for sentiment.
Important Note: Wild predators can reduce local rat activity, but pest control professionals generally agree that natural predators alone cannot resolve an established infestation, since rats reproduce faster than most predators can hunt them down.
1. Cats
The domestic cat (Felis catus) is probably the most familiar rat hunter on this list, but its wild relatives do the heavier lifting. In dense cities, feral and stray cats are frequently the most visible rat predator, alongside dogs and birds of prey, because in metropolitan environments, the primary predators threatening rats are feral cats, domestic dogs such as terriers, and urbanized hawks.
A pet cat’s interest in rats varies enormously by individual temperament and whether it has ever had to hunt for food. Wild and semi-wild cats are a different story — bobcats, servals, and feral colonies treat rodents as a dependable food source rather than a toy. Readers curious about which animals resist taming altogether, unlike the housecat, can compare notes in this piece on animals that can’t be domesticated.
2. Barn Owls
The barn owl (Tyto alba) is arguably the most efficient rodent hunter in the night sky, identifiable by its pale, heart-shaped face and silent flight. Its hunting output is remarkable: a single barn owl family can consume over 1,000 rodents in a year, which is handy pest control in agricultural areas.
Barn owls locate prey almost entirely by sound, using asymmetrically placed ear openings to triangulate a rat’s position in total darkness. Farmers in many regions install nest boxes specifically to encourage barn owl families to patrol grain stores and outbuildings, turning a wild predator into a low-cost pest management partner.
3. Rat Snakes
True to their name, rat snakes in the genus Pantherophis target rodents more consistently than almost any other prey type. These non-venomous constrictors are widespread, since rat snakes frequently prey on rats and can be found in urban areas, where they inhabit abandoned buildings and barns.
A rat snake kills by constriction, coiling around its prey and tightening with each exhale until the rat can no longer draw breath. Because they can follow rodents into burrows and wall cavities, rat snakes often end up living alongside the very rat populations they’re suppressing, unnoticed until someone spots a shed skin in the attic.
4. Corn Snakes
The corn snake (Pantherophis guttatus) is a close relative of the rat snake and shares its taste for rodents, which is one reason it has become one of the most commonly kept pet snakes worldwide. In captivity, this dietary preference is well documented, since rats are a common food item for snakes, both in the wild and as pets, and adult rat snakes and ball pythons are typically fed a diet of mostly rats.
In the wild, corn snakes ambush rodents in brush piles, farmland, and abandoned structures across much of the southeastern and central United States. Their docile temperament toward humans, combined with their appetite for rats, has made them a favorite among reptile keepers who breed feeder rodents specifically for snake diets.
5. Boas
Boas handle prey on an entirely different scale than smaller constrictors. The boa constrictor (Boa constrictor) swallows its meals whole, and larger boas can eat a whole monkey, pig, or deer, suffocating their prey by squeezing it with powerful muscles before eating it.
For a boa, a rat is an easy, low-risk meal compared to the larger prey it’s capable of tackling. Smaller and juvenile boas in particular rely heavily on rodents, since the size and abundance of rats make them an efficient energy source without the danger that comes with hunting larger mammals.
6. Weasels
Few predators on this list match the sheer efficiency of the weasel. The long-tailed weasel (Mustela frenata) has incredibly sharp teeth and claws built for close-quarters hunting, and these animals eat frequently, can digest all parts of a rat, and will also take amphibians, small reptiles, birds, bird eggs, insects, and carrion when rats aren’t available.
A weasel’s slender body lets it chase rodents directly into their own burrows, eliminating the escape route that protects rats from larger predators. Their high metabolism means they must hunt almost constantly, making a weasel population one of the more persistent rat-suppression forces in a given area.
7. Bobcats
The bobcat (Lynx rufus) is a mid-sized wild cat found across much of North America, and rodents make up a dependable part of its diet alongside rabbits and birds. Wildlife removal specialists note that mountain lions, red foxes, and bobcats also hunt rats in addition to domestic and feral cats.
Unlike housecats, bobcats rely entirely on hunting success for survival, which makes them far more consistent and motivated rat predators. They’re also a clear example of a species that, despite looking superficially like an oversized housecat, belongs firmly on the list of animals that can’t be domesticated.
8. Cougars
The cougar (Puma concolor), also called the mountain lion or puma, typically hunts deer and other large mammals, but it won’t pass up a rodent when the opportunity arises. As one wildlife removal resource puts it, mountain lions commonly hunt rats, and when food is not abundant, a mountain lion will eagerly snap one up.
This opportunistic flexibility is part of what makes cougars such successful apex predators across such a wide range of habitats, from desert scrub to mountain forest. A rat is a trivial meal for an animal capable of taking down an elk, but it’s still calories worth collecting when bigger prey is scarce.
9. Terriers
Terriers (Canis lupus familiaris) are the only domesticated dogs purpose-bred for rat hunting, a trait that goes back centuries to their original role on farms and in stables. According to one pest control resource, several dog breeds are pretty good at hunting and killing rats and other small rodents, including Jack Russell Terriers, Dachshunds, German Pinschers, and Rat Terriers.
Common ratting breeds include:
- Jack Russell Terrier
- Rat Terrier
- Border Terrier
- Miniature Schnauzer
- Dachshund
These dogs combine small size, high prey drive, and the willingness to dig into burrows — exactly the traits needed to flush a rat out rather than simply chase it. For readers interested in other species grouped by name, the animals that start with T list covers terriers alongside several other notable species.
10. Opossums
The Virginia opossum (Didelphis virginiana) has an outsized reputation as a rat killer for an animal most people associate with playing dead. In practice, opossum predation on rodents is substantial, since the opossum is a major killer of rats in large numbers, potentially greater than the owl or mink.
Pro Tip: Opossums are also one of the few mammals that actively hunt ticks off their own fur, making them a double benefit for anyone dealing with both rodents and tick-borne disease risk — see animals that eat ticks for more on that behavior.
Opossums are largely nocturnal and spend much of the daylight hours denned up, which is part of why they’re grouped among the animals that sleep a lot. Despite their sluggish reputation, they’re aggressive and effective rat hunters once darkness falls.
11. Coyotes
The coyote (Canis latrans) has expanded its range into suburban and even urban environments across North America over the past several decades, and rodents are a reliable part of its varied diet. Research on predator-prey dynamics notes that coyotes have expanded their range significantly and are now common in suburban and urban areas, where rodents make up a meaningful portion of their diet.
Coyotes hunt rats opportunistically rather than specializing in them, picking off individuals while foraging for a broader mix of small mammals, fruit, and carrion. Like wolves and cougars, coyotes remain firmly wild in temperament, reinforcing why they also appear among animals that can’t be domesticated despite their close genetic relationship to dogs.
12. Raccoons
Raccoons (Procyon lotor) are generalist omnivores, and their reputation for raiding trash cans extends naturally to raiding rodent nests when the opportunity presents itself. Pest control references commonly group raccoons alongside snakes, cats, owls, and hawks as animals that prey on rats.
A raccoon’s dexterous front paws let it pry apart nesting material and dig into shallow burrows that would stop many other predators. Rats aren’t a primary food source for raccoons the way they are for weasels or owls, but a raccoon encountering a rat nest rarely passes up the easy protein.
13. Hawks
Daytime skies belong largely to hawks, and the red-tailed hawk (Buteo jamaicensis) is the most widespread example across North America. These raptors hunt rats by sight, and red-tailed hawks, found across most of North America, will hunt rats by day from elevated perches or while soaring over open ground.
A hawk’s keen eyesight lets it spot a rat’s movement from a considerable distance, after which it stoops in a fast, controlled dive and strikes with its talons. Hawks aren’t picky about prey type either, and the same birds that hunt rats also regularly take the animals covered in this guide to animals that eat snakes.
14. Falcons
Falcons round out the daytime raptor guild, with the American kestrel (Falco sparverius) standing out as the smallest and most common falcon across much of North America. Pest control literature groups falcons with the other major raptor hunters, noting that raptors such as owls, hawks, eagles, kestrels, and falcons all eat rats and rodents, relying on amazing sight and aerial ambush to incapacitate them.
Kestrels often hunt from telephone wires or fence posts, scanning open fields before dropping onto prey with precision. Their small size means they tend to target juvenile or smaller adult rats rather than the largest individuals in a colony.
15. Red Foxes
The red fox (Vulpes vulpes) is one of the most adaptable mammals in the Northern Hemisphere, equally at home in farmland, forest edge, and suburban neighborhoods. Its hunting pattern favors darkness, since foxes find more things to eat at night, when they don’t have to worry as much about larger predators such as wolves and humans.
A red fox locates rodents largely by sound, using its acute hearing to detect a rat moving under leaf litter or snow before pouncing with a distinctive high, arcing jump. This hunting style, sometimes called mousing, works just as well on rats as it does on voles and mice.
16. Gray Foxes
The gray fox (Urocyon cinereoargenteus) shares much of its range and hunting behavior with the red fox but is distinguished by an unusual ability among canids: it can climb trees. This lets gray foxes access denning sites and food sources that ground-bound predators can’t reach.
Like its red cousin, the gray fox is an opportunistic hunter that folds rodents into a broader diet of insects, fruit, and small mammals depending on seasonal availability. Both fox species are most active at dawn, dusk, and overnight, periods that overlap heavily with peak rat activity.
17. Wolves
Wolves (Canis lupus) are built for taking down large hoofed prey, but smaller mammals still appear in their diet when opportunity allows. One wildlife resource notes plainly that red wolves eat rodents like rats and mice alongside their more typical prey.
For a wolf pack, rodents are a minor supplement rather than a dietary staple, picked up incidentally while traveling through territory in search of larger game. Even so, the behavior illustrates how broadly rats factor into the diets of predators at every size class, from the smallest weasel to the largest wild canid.
18. Stoats
The stoat (Mustela erminea), also known as the short-tailed weasel or ermine, is a close relative of the weasel with a similarly ferocious hunting style. Like other mustelids, stoats are built for pursuit into tight spaces, and they have incredibly sharp teeth and claws that they employ when hunting rats, dispatching them relatively quickly.
Mustelids as a group are known for intense, food-driven aggression, and in periods of scarcity some species will even scavenge or compete over their own kind — an extreme illustration of the same pressures explored in this look at animals that eat their mates. A stoat’s high metabolism demands near-constant hunting, which keeps local rodent populations under consistent pressure.
19. Mink
The American mink (Neovison vison) is a semi-aquatic mustelid found near rivers, streams, and wetlands, where it hunts both aquatic prey and land-based rodents. Among mustelids, the mink is one of the most notable rat hunters, with its speed, slim size, and agility making it an excellent hunter that will even hunt rats for fun.
Mink are aggressive by nature and will kill more prey than they immediately need, caching surplus food near their den. This behavior, combined with their comfort in both water and on land, makes them effective at controlling rat populations along waterways where other predators rarely patrol.
20. Vultures
Vultures don’t typically hunt live rats, but as scavengers they play an important role in removing dead rodents from the landscape. Turkey vultures (Cathartes aura) are among the species that will take advantage of this food source, and in rural areas, hawks and vultures are commonly added to the list of animals that prey on rodents.
By consuming carcasses before disease can spread, vultures function as a sanitation service for the ecosystems they inhabit. This scavenging role connects directly to the broader topic of animals that eat carrion, a group that overlaps significantly with the predators covered throughout this guide.
21. Crows
Crows are intelligent, opportunistic omnivores, and the American crow (Corvus brachyrhynchos) will take rodents under the right circumstances even though it isn’t built like a true raptor. As one bird conservation group notes, along with vultures, eagles, gulls, and ravens, American crows feed upon animal carcasses, including roadkill.
Live rat predation by crows is less common and tends to be opportunistic rather than routine, since crows are not built for targeted hunting like specialized raptors such as owls or hawks, and their consumption of rodents typically focuses on individuals that are already highly vulnerable or deceased. A healthy adult rat is a genuine challenge for a crow, but sick, injured, or very young rodents are fair game.
22. Ravens
The common raven (Corvus corax) is considerably larger than a crow and has an even broader diet, built around both scavenging and active hunting. Ravens are known to prey on a wide range of small animals, and their diet includes carcasses, lizards, frogs, nestlings, fish, insects, rabbits, moles, and small to medium-sized rodents.
Ravens are notably intelligent problem-solvers, sometimes working in pairs to flush prey out of hiding or distract larger animals away from a food source. Their size and adaptability let them exploit rodent populations in both wild and human-altered landscapes, from farmland to landfill edges.
23. Ferrets
The domestic ferret (Mustela putorius furo) is a descendant of the European polecat and has been used by humans for rodent control for centuries. Historically, ferrets, though not native to many ecosystems, have been utilized for centuries as efficient rat hunters, a practice known as ferreting that’s still used in parts of Europe today.
| Mustelid | Typical Habitat | Domestication Status |
|---|---|---|
| Weasel | Fields, hedgerows, farmland | Wild |
| Stoat | Forests, grassland, northern climates | Wild |
| Mink | Rivers, wetlands | Wild (farmed for fur) |
| Ferret | Burrows, human-managed settings | Domesticated |
Unlike its wild mustelid relatives, the ferret’s long domestication has made it a working animal rather than a free-ranging predator, typically deployed by handlers to flush rodents from burrows rather than hunting independently.
24. Herons
Herons are better known for fishing than rodent hunting, but several species will take rats when the opportunity arises near water. The great blue heron (Ardea herodias) and similar wading birds use patience over speed, since herons wade through marshes and water bodies with long bills and precise movements, preying on rats that venture too close to their habitats.
A heron’s hunting method relies on standing motionless for long stretches before striking with a rapid stab of its bill, a technique that works just as well on a rat near the shoreline as it does on a fish. This behavior places herons among the broader group of animals that live in water, even though their diet extends well beyond aquatic prey.
25. Skunks
The striped skunk (Mephitis mephitis) is best known for its defensive spray, but it’s also an opportunistic omnivore that will eat rodents, insects, eggs, and carrion depending on what’s available. Skunks dig through soil and leaf litter in search of grubs and ground-nesting prey, and a vulnerable rat or rat nest falls well within their dietary range.
Skunks are generally more opportunistic than specialized when it comes to rats, picking off individuals rather than actively tracking colonies the way a weasel or snake would. Readers interested in other species grouped alphabetically can find skunks among the animals that start with S.
26. Eagles
Eagles are among the largest and most powerful raptors to include rats in their diet, typically as a supplement to larger prey like fish, rabbits, and waterfowl. The bald eagle (Haliaeetus leucocephalus) and other large raptors fit into a broader pattern in which owls and hawks are the primary aerial predators of rats, utilizing specialized talons and exceptional vision to hunt rodents during both day and night.
| Raptor | Primary Hunting Time | Hunting Method |
|---|---|---|
| Barn Owl | Night | Sound-based ambush |
| Red-tailed Hawk | Day | Aerial stoop from height |
| American Kestrel | Day | Perch-and-drop |
| Eagle | Day | Opportunistic strike |
Key Insight: Raptors collectively provide round-the-clock pressure on rodent populations — nocturnal species like barn owls cover the night shift while hawks, falcons, and eagles patrol by day, closing off a 24-hour predation window that few rat colonies can fully escape. Eagles also occasionally overlap with the predators featured in this piece on animals that eat snakes, since both prey types share similar open habitats.
An eagle’s size means a single rat is a minor snack rather than a primary food source, but during lean periods or in areas where larger prey is scarce, rodents provide an easy supplementary meal.
Taken together, these 26 species show that rat predation isn’t confined to any one habitat, hunting style, or branch of the animal kingdom. Cats and canids chase rats at ground level, raptors cover the skies by day and night, constrictors wait in ambush, and mustelids pursue rodents into their own burrows. The sheer diversity of predators targeting rats is a reminder of how central rodents are to food webs worldwide — and how much quiet ecological work these hunters do simply by following their own predatory instincts.
