Are Rabbits Rodents?

Rabbits are not rodents. While they may share some similarities with rodents, rabbits actually belong to a different taxonomic order called Lagomorpha. This order also includes hares and pikas. Rodents, on the other hand, belong to the order Rodentia, which includes mice, rats, squirrels, porcupines, beavers, guinea pigs, and many others.

The main difference between lagomorphs and rodents is that lagomorphs have an extra set of incisors in their upper jaw, behind their main pair of incisors. Rodents, in contrast, only have one set of incisors in their upper and lower jaws. Rabbits also have a distinct skull shape and other anatomical differences that set them apart from rodents.

In terms of behavior, rabbits are generally slower, less intelligent, and less aggressive than many rodents. While some rodents like rats and mice are omnivorous, rabbits are strict herbivores, feeding only on plant materials. Rabbits are also less destructive and better diggers than rodents.

While rabbits may remind people of rodents due to their small size and reputation for rapid reproduction, taxonomically they are in a separate order. Some key differences between rabbits and rodents include:

  • Rabbits have an extra set of incisors behind their main incisors. Rodents only have one set.

  • Rabbits have a distinct skull structure with a curved occipital region. Rodents have a flatter skull.

  • Rabbits are herbivorous, while rodents are omnivorous.

  • Rabbits are slower and less intelligent on average than rodents.

  • Rabbits are diggers, while rodents are gnawers.

  • Rabbits have a longer gestation period and smaller litters than rodents typically do.

So while rabbits and rodents share some superficial similarities, they are distinctly different types of mammals both taxonomically and in terms of anatomy, diet, behavior, and reproduction. Calling a rabbit a rodent would be inaccurate.

Differences Between Rabbits and Rodents

There are several key differences between rabbits and rodents in terms of their physiology, behavior, and lifestyles. Some of the main areas where rabbits differ from classic rodents like mice, rats, and squirrels include:


Rabbits are herbivores, adapted to digesting grasses, leaves, bark, and other plant materials. They have enlarged appendixes called cecums that allow them to break down cellulose. Rodents are omnivores and have more varied diets, including grains, fruits, vegetables, insects, and meat.


Rabbits have a longer gestation period of around 31 days and give birth to furless, blind babies. Rodents like mice and rats have gestation periods of 20-24 days and give birth to babies that are furred with their eyes open. Rabbits also nurse their young once a day versus rodents who nurse frequently.


As mentioned, rabbits have an extra set of incisors behind their front teeth. This gives them a total of 6 upper incisors compared to just 4 for rodents. Rabbits gnaw on food in a side-to-side motion versus rodents who gnaw up and down.


Rabbits have large powerful hind legs adapted for jumping and running. Their front paws have 5 toes while their back paws have 4 toes. Rodents have smaller rear feet with 4-5 digits on both front and back feet.


Rabbits have small, furry tails while rodents like squirrels, mice, and rats have prominent, scaly tails. Some rodents like beavers and guinea pigs lack visible tails.


Rabbits have excellent hearing and sense of smell. Nocturnal rodents like rats and mice have poor vision but excellent senses of smell, taste, and touch. Tree squirrels have sharp vision.

Social Structure

Rabbits usually live solitary lives and only pair up to mate. Rodents like rats, mice, and prairie dogs are highly social and live in organized colonies.

So in summary, rabbits and rodents differ significantly in their anatomy, digestion, reproduction, locomotion, senses, and social behavior. While both are small mammals, they have evolved distinct adaptations for their particular lifestyles.


Rabbits and rodents have very different digestive systems adapted to their particular diets. As herbivores, rabbits have evolved unique digestive tracts specialized for digesting grasses, leaves, and other plant foods. In contrast, rodents have more varied omnivorous diets requiring less specialized digestion.

Some key differences in digestion include:

  • Rabbits have enlarged cecums, a pouch connected to the intestines where cellulose is broken down by bacteria. Rodents have much smaller cecums.

  • The rabbit stomach has two types of glandular tissue to produce digestive enzymes. Rodents have a single stomach chamber.

  • Rabbits are hindgut fermenters, meaning digestion occurs primarily in the large intestine and cecum. Rodents are foregut fermenters.

  • Rabbits excrete two types of feces – moist night feces they ingest directly to further digest, and dryer waste pellets. Rodents just excrete single waste pellets.

  • The rabbit small intestine is much shorter relative to body size compared to rodents, at 8-10x body length versus 12-15x in rodents.

  • Rabbits cannot vomit unlike most rodents.

  • Rabbits must get their vitamins through cecotropes, special types of feces. Rodents do not ingest their feces to obtain nutrients.

  • The soft rabbit diet means they do not need as much chewing as rodents, thus have slower tooth growth.

So in summary, rabbits have a more specialized, complex digestive system tailored to extracting nutrients from fibrous, cellulose-rich plants. Their enlarged cecum, distinct stomach, lack of vomiting, and cecotrophy make their GI system very different from rodents adapted to more varied diets.


Rabbits and rodents also differ in their reproductive anatomy and behaviors. Some key differences include:

  • Rabbits have a longer gestation period of around 31 days versus 20-24 days for most rodents.

  • Rabbits give birth to furless, blind infants while rodents are born furred and with eyes open.

  • Rabbits only nurse their young once a day. Rodent mothers nurse more frequently.

  • Rabbits build open nests on the surface while rodents use complex burrows and chambers.

  • Rabbits can breed year-round unlike seasonal rodent breeders.

  • Rabbits produce smaller litter sizes, averaging 4-12 babies versus 5-10 for rats and up to 14 for mice.

  • Female rabbits can become pregnant again just hours after giving birth thanks to induced ovulation. Rodents enter a postpartum estrus period.

  • Rabbit kittens begin eating solids after 2 weeks versus 3-4 weeks for rodent pups.

  • Rabbits reach sexual maturity in 4-6 months while rodents take 2-3 months.

So rabbits and rodents have clear reproductive differences in terms of gestation lengths, litter sizes, nesting behaviors, breeding frequency, and sexual maturation rates. Rabbits evolved adaptations like rapid re-mating and frequent breeding for high fecundity.

Rodents vs. Rabbits Compared

Here is a summary comparing and contrasting some key traits between rabbits and rodents:

Teeth – Rabbits have an extra pair of upper incisors. Rodents have just one upper pair. Rabbits gnaw side-to-side, rodents up and down.

Diet – Rabbits are herbivores, rodents are omnivores. Rabbits have more specialized digestion.

Social Structure – Rabbits are mainly solitary, rodents can be social. Rabbits do not colony.

Reproduction – Rabbits have longer gestation, smaller litters, less maternal care than rodents.

Predators – Rabbits rely on speed, rodents use burrows. Rabbits are prey for many animals.

Appearance – Rabbits have long ears and legs, short tails. Rodents have prominent tails, shorter limbs, smaller ears.

Senses – Rabbits have good hearing/smell. Rodents also have strong smell and touch.

Behavior – Rabbits are slower, less intelligent on average than rodents.

Habitat – Rabbits live in open habitats like meadows. Rodents occupy diverse habitats including human dwellings.

Movement – Rabbits bound using hind legs. Rodents walk/climb using all four limbs.

So in summary, while sharing some characteristics as small mammals, rabbits and rodents differ substantially in anatomy, physiology, behavior, intelligence, social structure, and environmental niche. They represent distinct branches of mammalian evolution.

Are Rats Or Rabbits Smarter?

When comparing the intelligence of rats versus rabbits, the evidence indicates that rats generally demonstrate greater intellectual abilities:

  • Learning Tests – Rats perform better on mazes and other learning/reasoning tests. They remember solutions for longer.

  • Tool Use – Rats can be taught to use simple tools. Rabbits do not use tools in nature.

  • Analysis – Rats show more ability to assess complex or new situations. Rabbits rely more on instinct.

  • Training – Rats can be taught a wide array of tricks, behaviors, and tasks. Rabbits are less easily trained.

  • Social – The social nature of rats requires greater intelligence to have organized colonies. Rabbits are mainly solitary.

  • Adaptability – Rats are generalists able to thrive in many environments. Rabbits are limited to certain grassland habitats.

  • Problem Solving – Rats demonstrate their intelligence solving mazes, puzzles and extracting food. Rabbits show less complex problem solving abilities.

  • Brain Structure – The rat brain has greater corticalization and more distinct learning/memory regions compared to rabbits.

  • Predator Avoidance – Rats rely on their wits to evade predators. Rabbits use speed and camouflage rather than intelligence.

While rabbits are not unintelligent animals, their brain structure, behavior, adaptability, and performance on cognitive tests all indicate rats have superior intelligence compared to their lagomorph cousins. Rats need greater intellectual abilities given their omnivorous diets, social colonies, and lack of natural defenses. Rabbits rely more on their senses, speed, and instinct rather than brain power.

Do Rats or Rabbits Breed Faster?

When it comes to reproduction, rabbits breed significantly faster than rats. Some key reasons why rabbits have higher fecundity include:

  • Gestation Period – Rabbits have a shorter gestation period of just 31 days versus 20-24 days for rats.

  • Litter Size – Rabbits produce up to 14 young per litter, with averages of 4-12. Rats litter sizes range from 5-10 pups.

  • Time Between Litters – Female rabbits can become pregnant again within hours of giving birth. Rats go through a postpartum estrus period before breeding again.

  • Maturation Rate – Young rabbits reach sexual maturity in 4-6 months versus 2-3 months for rats. However, rats can begin reproducing even earlier.

  • Breeding Season – Rabbits breed year-round. Rats in seasonal climates restrict breeding to spring and summer.

  • Maternal Care – Rabbit mothers nurse their young just once a day. Rat mothers are continuously nursing and caring for pups.

  • Population Density – When food is abundant, rabbit populations can experience dramatic booms. Rats breed abundantly but cannot match rabbit reproductive output.

So while rats have high reproductive capacity and can breed prolifically in optimal conditions, rabbits overall can reproduce new generations much faster. Their ability to be continuously pregnant and nursing, extremely short gestation, and very large litter sizes gives rabbits the breeding advantage. This reproductive speed allows rabbit populations to explode when conditions are right. Rats cannot match the sheer fecundity of rabbits.

So in summary, while rats breed abundantly, rabbits are the faster reproducers and can generate new generations more rapidly thanks to shorter gestations, larger litters, year-round breeding, rapid sexual maturation, and continuous pregnancies. Rabbits evolved as prey animals requiring high reproductive rates to survive predation. This makes them the champions of breeding speed in the rodent versus rabbit competition.
