Are Possums Rodents?

You may have seen opossums scurrying around at night and have mistaken them for rodents. But they belong to a different order of mammals known as the Marsupials. Possums are related to kangaroos and koalas; all three animals share similar features.

Although possums possess some characteristics of rodents, such as their sharp claws and long tails, they are not classified as rodents. Let’s take a look at some of the key contrasts that set possums apart from rodents.

Key Pest Points:

•  Opossums are marsupials, not rodents. They are natural competitors of rats and can help keep them away from your property.

•  They are born tiny and must crawl into their mother’s pouch to get the nutrients they need to grow strong and healthy.

•  Possums benefit gardens since they eat insects and pests, disperse native plant seeds, and help maintain a healthy ecosystem.

•  These creatures can be found worldwide and come in many varieties, like the tiny pygmy possum or the incredible sugar glider.

What Are Rodents?

From the desert to your backyard, rodents have adapted and spread across nearly every corner of the world. Many species within this fascinating mammalian order exist today, including rats, mice, beavers, and squirrels. Here are the key features that define a rodent:

  • They have one pair of constantly growing upper and lower incisors used for gnawing on hard surfaces.
  • Rodents are omnivores, so their diet typically consists of plants and seeds. Some species can also feed on insects and even meat.
  • Their bodies are generally stout with short limbs and a tail that is typically scaly or hairy.
  • They are mostly active during the night time hours or nocturnal animals, but some species are diurnal as well.

These features set rodents apart from other types of mammals, including possums.


The word rodent means “to gnaw” in Latin and is derived from the word rodere, which means “to scrape” or “to eat away”. This explains why these animals are known for their sharp incisors and unique way of eating.

Differences Between Possums and Rodents

Although possums share some traits with rodents, a few key differences set them apart. These include:

  • Possums are marsupials and have a pouch in which their young develop. This is not seen in any other type of mammal.
  • Their size is generally larger than that of most rodents. Possums can be 30 – 35 cm long, while rats can grow to 25 cm long.

Hopefully, this clears up any confusion surrounding whether or not possums are considered to be rodents.

What are Marsupials?

Marsupials are a unique group of mammals that gives birth to relatively undeveloped young. They carry them in a pouch until they’re old enough to survive.

Marsupial babies develop differently than those born from placental mammals like us humans or our furry friends. Gestation is around 8 – 46 days, which depends on the species. 

They are remarkable animals that inhabit a wide variety of environments. From the tiny marsupial mouse no bigger than your hand to the massive kangaroo towering over 6 feet tall – they have adapted fascinatingly well in their respective habitats.

Unfortunately, threats such as habitat destruction, invasive species, and hunting cause certain species. However, these incredible creatures remain essential to global biodiversity by providing pollination services or dispersing seeds across various regions.

As such, efforts to protect and conserve these fascinating creatures are critical to maintaining a healthy life balance on Earth.

Physical and Behavioral Traits of Possums

Possums are marsupials found in Australia and the Americas. They are renowned for their distinctive physical and behavioral traits. Possums have soft and fluffy fur that can be gray, brown, or black. Their thick tails, which can be prehensile, help them maneuver through trees, and their powerful hind legs allow them to jump up to 1 meter high. Possums also have sharp claws that cling to branches and trunks.

In terms of their behavior, possums are nocturnal. They prefer to sleep in tree hollows, branches, or other sheltered areas during the day. At night, possums actively forage for food, primarily insects, fruits, and leaves. 

Possums are also known for their unique defense mechanism, “playing possum,” where they feign death by rolling onto their back and becoming unresponsive. They do this to deter predators and buy time to escape.

Another notable aspect of possums is their reproductive biology. Female possums have a bifurcated reproductive system, with two separate uteri and vaginal openings. 

Overall, possums have unique physical and behavioral traits that help them thrive in their environment. Their resilience and fascinating behavior have made them a popular subject in both scientific and cultural contexts.

Types of Possums Around the World

Possums are one of nature’s most fascinating marsupials. With various species boasting different characteristics like prehensile tails for climbing and grasping objects or nocturnal habits – possums show off their unique features. Here are just a few of the possums found around the world.

  • Sugar glider (Petaurus breviceps): a small nocturnal marsupial endemic to Australia and New Guinea. This cutie can glide through the air using membranes attached to its arms and legs.

Possums are incredibly adaptive creatures who always seem to find new ways of surviving their environments. It makes you wonder what other fascinating discoveries we might make about them in future studies.

How Can Opossums Benefit Your Garden

Opossums are often a nuisance, but they can benefit your garden in various ways. These creatures are omnivorous and will feast on multiple insects and pests, including slugs, beetles, and snails. By reducing pest populations, opossums can help to maintain a healthy ecosystem in your garden.

In addition, opossums are natural seed dispersers. They consume fruits and berries and then move on to a new area, depositing the seeds in their droppings. This process can help to spread native plant species throughout your garden, promoting biodiversity and reducing the likelihood of invasive species taking over.

How to Prevent Possums from Living on Your Property

Possums are notorious for causing destruction and chaos around homes, and keeping them away from your property can be daunting. However, there are several things you can do to help prevent possums from making your home their habitat. 

  • Secure your food: place food sources in sturdy, airtight containers, such as trash cans, compost bins, and pet food. 
  • Removing fallen fruit or nuts: pick up fallen fruit and nuts in your yard, as these can attract possums.
  • Eliminate hiding spots: trim shrubs and trees to reduce the number of hiding spots where possums may take shelter.
  • Install fencing: erect a fence at least 3 feet tall around your property. Ensure the fence extends below the ground surface to prevent possums from digging under it.
  • Using scent repellent tactics: use scent repellents around your property to deter possums, such as peppermint oil, ammonia, or garlic. 
  • Trap the possum humanely: if a possum has already taken up residence on your property, you can use traps to remove them humanely and relocate them far from your home.

By implementing these measures, you can successfully prevent possums from making your property their home and enjoy a peaceful, possum-free environment.


Why is a possum not a rodent?
