Possums and rats often live in close proximity, either in urban or rural environments. This leads many to wonder – do possums actually eat rats? Read on to learn whether possums prey on rats, and what these nocturnal marsupials really like to eat.

If you’re short on time, here’s a quick answer: While possums certainly can and occasionally do eat rats and other rodents, this does not make up a significant portion of their diet. Possums are omnivorous and opportunistic feeders that prefer plant-based foods like fruits, vegetation, nuts, and seeds.

An Overview of the Possum Diet

Omnivorous Scavengers

Possums are known for their opportunistic and adaptable nature when it comes to their diet. They are classified as omnivorous scavengers, meaning they have a wide range of food options available to them. This flexibility allows them to survive in various habitats, from urban areas to forests.

While possums primarily feed on plant matter, they are not averse to consuming animal protein when the opportunity arises. This includes small animals like rats, mice, and even insects. However, it is important to note that rats are not a staple part of a possum’s diet and are not their preferred food source.

Preferred Foods

The possum’s preferred diet consists of fruits, vegetables, nuts, and seeds. They are particularly fond of fruits such as apples, berries, and melons. Additionally, possums enjoy feasting on the tender shoots and leaves of various plants, including eucalyptus and acacia trees.

Possums also have a taste for insects, such as beetles, caterpillars, and slugs, which they often find while foraging in gardens or rummaging through compost piles. They play a crucial role in controlling the population of these pests, making them beneficial for gardeners and farmers.

Hunting and Foraging Behaviors

Possums are primarily nocturnal animals, which means they are most active during the night. They have a keen sense of smell and use it to locate food sources. Their sharp claws and prehensile tails enable them to climb trees with ease, allowing them to access fruits and flowers that are otherwise out of reach.

When hunting for small prey like rats, possums rely on their sharp teeth and strong jaws to catch and consume them. However, it is important to note that possums are not natural predators of rats and would typically only consume them if they come across them while searching for other food.

Do Possums Actually Eat Rats?

Possums are known to have a diverse diet, consisting of both plant matter and small animals. While they primarily feed on fruits, flowers, insects, and small vertebrates, there have been documented instances where possums have been observed eating rats.

Documented Instances of Possums Eating Rats

Although it is not their preferred food source, possums have been known to consume rats in certain situations. In urban areas where food sources may be limited, possums have been observed scavenging for food, and this can include rats.

Rats are small mammals that provide a source of protein for possums when other food options are scarce.

One particular study conducted in a suburban area found that possums consumed rats in approximately 10% of their diet. While this percentage may seem small, it does indicate that possums are opportunistic eaters and can adapt their diet based on availability.

Why Possums Don’t Rely on Rats as a Food Source

Despite the occasional consumption of rats, possums do not heavily rely on them as a primary food source. There are several reasons why possums do not actively seek out rats for sustenance.

  • Dietary preferences: Possums are primarily herbivorous creatures, and their digestive system is not designed to handle a diet heavy in meat. They are more adapted to digesting plant matter, such as fruits and leaves.
  • Other food sources: Possums have a wide range of food options available to them, including fruits, vegetables, insects, and small invertebrates. These food sources are more easily accessible and provide the necessary nutrients for their survival.
  • Size and agility: Possums are relatively small creatures compared to rats, and they are not as agile or fast. Rats, on the other hand, are known for their ability to evade predators. This makes it difficult for possums to actively hunt rats as a food source.

Other Rodents Possums May Prey On

While possums may not heavily rely on rats as a food source, they do prey on other rodents when the opportunity arises. This includes mice, voles, and small squirrels. These small mammals provide a similar source of protein and are more easily caught by possums due to their size and behavior.

It’s important to note that possums are generally not a threat to humans or pets. They play a crucial role in the ecosystem by controlling insect populations and helping to disperse seeds. If you happen to come across a possum in your backyard, it’s best to give them their space and let them continue their important work.

When and Why Possums Might Eat Rats

Scavenging Rat Carcasses

While possums are primarily herbivores, there are instances where they may consume rats. One such occasion is when possums come across rat carcasses. Possums are opportunistic eaters and will scavenge on any available food sources, including dead animals.

So, if a possum stumbles upon a dead rat, it may choose to feed on it.

Hunting Rats When Other Food is Scarce

Possums typically feed on fruits, leaves, insects, and small animals like mice and birds. However, in times when their usual food sources are scarce or limited, possums may resort to hunting rats as an alternative food option.

They are known to be omnivorous and can adapt their diet depending on the availability of food in their environment.

Eating Rats to Eliminate Competition

Another possible reason why possums might eat rats is to eliminate competition for resources. Rats are known to be opportunistic scavengers and can consume the same food sources as possums. In order to reduce competition for food, possums may prey on rats to ensure they have access to sufficient resources.

It’s important to note that while possums may eat rats in certain situations, it is not their primary diet. Possums are generally not considered as predators of rats and are unlikely to actively seek them out as a food source.

Their diet mainly consists of plant matter and small animals that are easier to catch and consume.

Preventing Possums From Eating Rats on Your Property

Possums are known to have a diverse diet, but do they actually eat rats? While possums are opportunistic feeders and will consume a variety of foods, including insects, fruits, and small animals, they are not typically known for preying on rats.

However, it is essential to take preventive measures to ensure that rats do not become a problem on your property. Here are some effective strategies to consider:

Securing Food Sources

One of the best ways to prevent possums and rats from coexisting on your property is by securing food sources. Possums are attracted to easily accessible food, so it’s important to store any potential food sources, such as pet food or birdseed, in sealed containers.

Additionally, make sure to clean up any fallen fruits or vegetables from your garden, as these can also attract possums and indirectly attract rats.

It’s also a good idea to remove any potential nesting sites for rats, such as piles of debris or wood. By keeping your property clean and free from clutter, you can discourage both possums and rats from taking up residence.

Excluding Possums from Rat Habitats

Possums and rats may inhabit similar areas, such as attics, crawl spaces, or under decks. To prevent possums from accessing these spaces, it’s important to seal off any potential entry points. Inspect your property for any gaps or holes larger than a quarter inch, as possums can squeeze through remarkably small openings.

Use materials like wire mesh or metal flashing to cover these gaps and prevent both possums and rats from gaining access.

Using Repellents and Deterrents

If you’re concerned about possums and rats on your property, you can use repellents and deterrents to discourage their presence. There are various commercial sprays and granules available that can be applied to areas where possums and rats are frequently seen.

These products typically contain natural ingredients that emit scents possums find unpleasant, such as garlic or mint.

Additionally, installing motion-activated lights or sprinkler systems can startle and deter both possums and rats from frequenting specific areas. These devices are designed to be triggered by movement, providing an effective means of discouraging these creatures from entering your property.

Remember, prevention is key when it comes to managing possums and rats on your property. By securing food sources, excluding possums from potential habitats, and using repellents and deterrents, you can help create an environment that is less appealing to these animals.


While possums are certainly capable of catching and eating rats, they tend to prefer plant-based foods and easier prey. Rats make up a very small portion of the possum diet. Focus on excluding possums from rat habitats and securing any outdoor food sources to prevent unwanted possum scavenging.

With some preventative measures, you can minimize interactions between possums and rats on your property.
