Kangaroo rats are small rodents that live in North America and Central America. They are called "kangaroo rats" because they hop around on their strong back legs, just like tiny kangaroos! Even though they look a bit like kangaroos, they are not closely related. They are both mammals, but that's about it.
There are about 22 different species of kangaroo rats. They can be anywhere from 10 to 20 centimeters (about 4 to 8 inches) long, not counting their tail. Adult kangaroo rats usually weigh between 35 and 180 grams (about 1 to 6 ounces).

What Do Kangaroo Rats Look Like?
Kangaroo rats have some cool features that help them live in their dry homes.
- Size: They are small, usually about 10 to 15 centimeters (4 to 6 inches) long, not including their tail.
- Tail: Their tail is even longer than their body, often 12 to 20 centimeters (5 to 8 inches) long. It has a tuft of fur at the end, which helps them balance when they hop.
- Fur: They have soft fur that is usually a sandy or brownish color. This helps them blend in with the desert ground, making it harder for predators to spot them.
- Legs: Their back legs are much longer and stronger than their front legs. This is what allows them to hop quickly and jump far.
- Eyes: They have big eyes that help them see well at night, since they are mostly active after the sun goes down.
Where Do Kangaroo Rats Live?
Kangaroo rats live in dry places, like deserts and semi-desert areas. You can find them in parts of the United States and Mexico. They prefer areas that have some grass or other vegetation left, even if the climate is very dry.
Here are some states in the U.S. where you might find them:
They build their homes in burrows, which are tunnels they dig in the ground. These burrows are like underground houses that protect them from the hot sun during the day and from animals that might try to eat them at night.
What Do Kangaroo Rats Eat?
Kangaroo rats mostly eat seeds, but they also munch on leaves, nuts, and other fruit they can find. Sometimes, they even catch and eat insects. They are also known for storing food in their burrows, like a pantry, so they have something to eat when food is scarce.
One of the most amazing things about kangaroo rats is that they usually don't need to drink water! They get all the water they need from the seeds they eat. Their bodies are super good at saving water, which is really important in the dry places where they live.
Kangaroo Rat Behavior
Kangaroo rats are nocturnal, meaning they are most active at night. During the day, they stay safe and cool in their burrows. Here are some interesting things about how they behave:
- Hopping: They hop around on their back legs to move quickly. They can jump pretty far, which helps them escape from predators.
- Burrowing: They dig complex burrows with different rooms for sleeping, storing food, and raising their babies.
- Cheek Pouches: They have special fur-lined pouches in their cheeks. They use these like shopping bags to carry lots of seeds back to their burrows!
- Dust Baths: Kangaroo rats keep their fur clean by taking dust baths. They roll around in the dirt to get rid of extra oil and dirt.
- Territorial: They are territorial, which means they defend their burrows and the area around them from other kangaroo rats.
Unlike many other animals, kangaroo rats don't sweat or pant to stay cool. This helps them avoid losing precious water in their dry environment.
Types of Kangaroo Rats
There are many different kinds of kangaroo rats. Here are a few common ones:
- Ord's Kangaroo Rat (Dipodomys ordii): This is one of the most common kangaroo rats. They live in many different places, from grasslands to deserts.
- Merriam's Kangaroo Rat (Dipodomys merriami): These kangaroo rats are smaller than Ord's kangaroo rats. You can find them in the southwestern United States and Mexico.
- Desert Kangaroo Rat (Dipodomys deserti): As their name suggests, these kangaroo rats live in very dry deserts. They are larger than other kangaroo rats and have very pale fur.
- Banner-tailed Kangaroo Rat (Dipodomys spectabilis): These kangaroo rats are known for their large tails with a white "banner" at the end. They build large mounds of dirt around their burrows.
Who Hunts Kangaroo Rats?
The desert can be a dangerous place, and kangaroo rats have many animals that hunt them, including:
Why Are Kangaroo Rats Important?
Kangaroo rats play an important role in their ecosystem. Here are some ways they help the environment:
- Seed Dispersal: When they collect seeds and store them, they sometimes bury them and forget about them. These forgotten seeds can then grow into new plants, helping the desert environment.
- Soil Aeration: When they dig their burrows, they help mix up the soil. This makes the soil better for plants to grow because it allows air and water to get in.
- Food Source: They are a food source for other animals like owls, snakes, and coyotes, helping to keep the food chain balanced.
Conservation Status
Most kangaroo rat species are doing well in the wild right now. However, some species are endangered because they have lost much of their habitat. For example, the giant kangaroo rat and the Stephens' kangaroo rat are both threatened. This is mainly because their homes are being taken over by farming, cities, and towns.
Fun Facts About Kangaroo Rats
- Kangaroo rats can jump up to 2.7 meters (9 feet) in a single leap!
- They can hear very low-frequency sounds, which helps them detect predators even before they get close.
- They can close their ears to keep sand out when they are digging.
- They live in deep burrows that protect them from the worst heat of the day.
- They only rarely need to drink water. Instead, they have a very efficient metabolism that lets them get water from the food they eat.
- They can live for up to 5 years in the wild.
Scientific Classification
Here's how scientists classify kangaroo rats:
- Kingdom: Animalia (They are animals)
- Phylum: Chordata (They have a backbone)
- Class: Mammalia (They are mammals, like us!)
- Order: Rodentia (They are rodents)
- Family: Heteromyidae
- Genus: Dipodomys
