Rats and squirrels are two common rodents that often live in close proximity. You may have wondered – do rats actually eat squirrels? The short answer is yes, rats do sometimes eat squirrels when given the opportunity.

In this approximately 3000 word article, we’ll take an in-depth look at the diets and behaviors of rats and squirrels to understand when and why rats may prey on squirrels.

The Opportunistic and Omnivorous Nature of Rats

Rats, known for their resourcefulness and adaptability, have an opportunistic feeding behavior. They are capable of thriving in various environments and can make use of a wide range of food sources. This adaptability allows them to survive in both urban and rural areas, making them one of the most successful mammalian species on the planet.

Rats Are Opportunistic Feeders

Rats are opportunistic feeders, meaning they take advantage of whatever food resources are available to them. This includes scavenging for food scraps, raiding garbage bins, and even consuming the remains of other animals.

While rats are not typically known for hunting and killing larger animals, they can prey on smaller animals such as squirrels under certain circumstances.

It is important to note that rat predation on squirrels is relatively rare and occurs primarily in cases where there is a scarcity of other food sources. Rats are more likely to consume squirrel eggs or newborns when they have access to their nests.

However, it is uncommon for rats to actively hunt and kill adult squirrels.

Rats Are Omnivores

Rats are classified as omnivores, which means they have a diet that consists of both plant and animal matter. This versatility in diet allows rats to survive in a variety of habitats and adapt to changing food availability.

While rats primarily feed on grains, fruits, and vegetables, they are also known to consume insects, small mammals, and birds.

It is worth mentioning that rats are highly adaptable and can adjust their dietary preferences based on the food sources present in their environment. For example, in urban areas where human food waste is abundant, rats may rely more heavily on processed foods and discarded leftovers.

Rats Have Varied Diets

Rats have a diverse diet, feeding on a wide range of foods depending on their surroundings. Their ability to consume almost anything allows them to occupy a variety of ecosystems, from fields to sewers.

In urban environments, rats can feed on food waste, pet food, and even gnaw through packaging to access stored food items.

It is important to note that while rats are adaptable and can eat a wide variety of foods, their diet should not include toxic substances or foods that are harmful to their health. Proper waste management, securing garbage bins, and eliminating potential food sources can help prevent rat infestations and reduce the risk of conflict between rats and other animals in urban areas.

Squirrels as Prey for Rats

Rats are opportunistic feeders and will eat a variety of foods, including small animals like squirrels. While rats are not known to specifically target squirrels as their primary prey, they may opportunistically prey on them in certain situations.

Baby Squirrels are Vulnerable

One reason why rats may target squirrels is because baby squirrels are vulnerable and easier to catch. Baby squirrels are often left unattended by their mothers, making them an easy target for rats looking for a quick meal.

Rats have been known to snatch baby squirrels from their nests, especially when food sources are scarce.

Injured or Sick Squirrels are Easy Targets

Rats are known to prey on injured or sick animals, and squirrels are no exception. If a squirrel is injured or sick, it may be slower or weaker, making it an easy target for rats. Rats are quick and agile predators, and they can easily take advantage of any weakness in their prey.

Squirrels Can Defend Themselves

While rats may prey on squirrels in certain situations, it is important to note that squirrels are not defenseless. Squirrels are agile and have sharp claws and teeth that can be used to defend themselves.

They are also known to be territorial and will defend their nests and food sources from intruders, including rats.

It is worth mentioning that the predation of rats on squirrels is not a common occurrence and is more likely to happen in urban areas where there is a high population density of both rats and squirrels. In natural habitats, the chances of rats preying on squirrels are relatively low.

When Rats Attack and Eat Squirrels

Rats are opportunistic creatures that will scavenge for food wherever they can find it. While they primarily feed on grains, fruits, and vegetables, they are known to exhibit carnivorous behavior as well. This includes eating other small animals, such as squirrels.

Scavenging Already Dead Squirrels

One way rats may come into contact with squirrels is by scavenging already dead ones. Rats are known to be attracted to the smell of decaying flesh, and if they stumble upon a dead squirrel, they may not hesitate to feast on it.

This behavior is more common in urban areas where rats have easier access to trash and waste.

Ambushing Young, Sick or Injured Squirrels

Rats are opportunistic hunters and will prey on smaller and weaker animals when given the chance. This includes young, sick, or injured squirrels that may be easier targets. Rats have sharp teeth and claws that allow them to overpower and consume squirrels that are in a compromised state.

However, it’s important to note that such occurrences are relatively rare.

Fighting Adult Squirrels

While it’s not common for rats to directly attack and eat adult squirrels, they may engage in territorial disputes or fights over food. Rats are known to be aggressive, and if they feel threatened or if resources are scarce, they may resort to fighting with squirrels.

However, adult squirrels are generally more agile and will likely be able to defend themselves against rats.

It’s important to remember that these interactions between rats and squirrels are not the norm and do not represent the typical behavior of either species. Rats are primarily scavengers and will typically avoid direct confrontation with larger animals.

Preventing Rats from Attacking Squirrels

Protecting Squirrel Nests and Young

One of the most effective ways to prevent rats from attacking squirrels is by protecting their nests and young. Rats are opportunistic and will target vulnerable squirrel nests to feast on the young ones.

To safeguard squirrel nests, it’s important to make sure they are built in secure locations that are inaccessible to rats. This can be done by placing nest boxes high up in trees or installing baffles around the trunks to prevent rats from climbing.

Deterring Rats

To deter rats from approaching squirrel habitats, there are several steps that can be taken. First, it’s essential to eliminate any potential food sources that may attract rats. This includes securing garbage cans with tight-fitting lids, cleaning up fallen birdseed or fruit, and sealing off any openings in buildings or fences that may provide access to rat nests.

Additionally, using rat repellents or natural deterrents such as peppermint oil or mothballs around squirrel nests can help keep rats at bay.

Providing Alternative Food Sources

Rats are more likely to attack squirrels if they are struggling to find food elsewhere. By providing alternative food sources for rats, such as designated feeding stations or feeding them away from squirrel habitats, you can help divert their attention away from squirrels.

This can be done by placing rat-friendly food like grains or seeds in specific areas where rats are known to frequent. However, it’s important to note that this method should be used cautiously, as it may attract more rats to the area if not managed properly.

The Complex Relationship Between Rats and Squirrels

Rats and squirrels, both belonging to the rodent family, have a complex relationship that is influenced by various factors such as competition for food and shelter, disease transmission risks, and their ability to coexist in shared urban environments.

Competition for Food and Shelter

Rats and squirrels are known to compete for limited resources such as food and shelter. Both species have a similar diet that includes nuts, seeds, fruits, and grains. This can lead to conflicts as they search for the same food sources.

In urban areas, where resources may be scarce, this competition can intensify.

It is important to note that while rats are omnivorous and will eat almost anything, squirrels primarily rely on plant-based foods. However, in times of scarcity, squirrels may resort to eating insects, bird eggs, or even small birds.

This can potentially lead to a clash with rats, as they are opportunistic feeders and may prey on smaller animals, including squirrels.

Disease Transmission Risks

Both rats and squirrels can carry and transmit diseases to humans and other animals. Rats, in particular, are known carriers of diseases such as leptospirosis, hantavirus, and salmonellosis. Squirrels, on the other hand, are known to carry ticks and fleas, which can transmit diseases such as Lyme disease.

While the risk of disease transmission from squirrels to humans is relatively low, it is important to take precautions when in close proximity to these animals. Avoid direct contact with squirrels, especially if they appear sick or injured, and always wash your hands thoroughly after handling them or their droppings.

Coexistence in Shared Urban Environments

Despite the competition and disease transmission risks, rats and squirrels have managed to coexist in many urban environments. This is mainly due to their ability to adapt and find alternative food sources and shelter.

In urban areas, both species can utilize human-made structures such as buildings, attics, and gardens as their habitats.

It is worth mentioning that some cities have implemented initiatives to manage rodent populations, aiming to minimize conflicts and potential health risks. These initiatives often involve pest control measures, public education campaigns, and the implementation of proper waste management practices.


In summary, rats are omnivorous opportunistic feeders that will eat squirrels when the chance arises, especially younger, injured or unwell ones. However, healthy adult squirrels can often defend themselves from rat attacks.

While rats pose some predatory threat, squirrels also help limit rat populations by competing for resources. The complex relationship between these two common urban rodents is part of the broader food web.
