When considering the compatibility of various pets in a shared living environment, it is essential to consider their differing needs, temperaments, and natural inclinations.

Among many potential pet combinations, one might wonder if rats and hedgehogs can live together peacefully and safely.

Rats, known for their intelligence and social nature, can be rewarding pets.

On the other hand, hedgehogs are solitary animals that require different environmental conditions and care.

As such, combining these two species in the same living space must be approached with caution and a deep understanding of each animal’s requirements.

This article will delve into the factors that come into play when housing rats and hedgehogs together, weighing the potential challenges and the necessary precautions to ensure a harmonious coexistence.


Natural Habitats of Rats and Hedgehogs

Rat Natural Habitats

Rats are incredibly adaptable creatures that can thrive in a range of environments. They are native to various regions worldwide, from Asia to Europe, and have been introduced to new habitats, such as North America and Australia.

Some typical habitats where rats can be found include:

  • Urban environments: Rats exist in large numbers in cities and towns, making their homes in sewers, garbage dumps, and buildings.
  • Agricultural areas: Rats can be found in fields, barns, and grain storage facilities, as they seek food in these locations.
  • Woodlands: Rats can also live in forests, often nesting in tree hollows or burrows.

Hedgehog Natural Habitats


Hedgehogs, conversely, are native to Europe, Africa, and Asia. They prefer habitats that provide ample opportunities for foraging and shelter.

These animals are not found in Australia or the Americas. Some of their usual habitats include:

  • Grasslands: Hedgehogs thrive in grassy areas, as they offer plenty of insects and other food sources and places to hide from predators.
  • Woodlands: Like rats, hedgehogs can also be found in forests, usually close to the edge, with a mix of vegetation and open areas.
  • Urban environments: Hedgehogs are quite adaptable and can be found in gardens, parks, and cemeteries, where they can forage for insects, slugs, and snails.

In conclusion, rat and hedgehog natural habitats are pretty diverse, and both species can survive in various environments, including urban settings. However, some differences in their natural habitats can impact their compatibility when living together.


Physical and Behavioral Differences

Rat Physical and Behavioral Attributes


Rats are medium-sized rodents with a long, hairless tail and sharp incisors. They typically measure 9 to 11 inches in length, including the tail, and weigh between 350 and 450 grams. Rats have strong adaptability and are known for their intelligence and resourcefulness.

Rats are social creatures and prefer living in groups called packs. They communicate through various vocalizations, body postures, and facial expressions.

Rats are omnivores, feeding on a diet that includes fruits, vegetables, grains, insects, and even small animals like birds or reptiles.

Rats are nocturnal, active predominantly at night, and sleep during the day. They have natural burrowing instincts and prefer to create burrows or nests in secluded, dark places.


Hedgehog Physical and Behavioral Attributes


Hedgehogs are small, nocturnal mammals with short legs and a distinct coat of sharp spines. They have a body length of 5 to 12 inches and weigh between 350 and 700 grams.

Hedgehogs have poor eyesight but compensate with an excellent sense of smell and hearing, allowing them to navigate and find food in their environment.

Hedgehogs are solitary animals and primarily interact with others during the breeding season. They communicate through hissing, snuffling, and other vocalizations.

Hedgehogs are insectivores, feeding primarily on insects, larvae, worms, and even small vertebrates like frogs.

When threatened, hedgehogs roll into a tight ball to protect their vulnerable underside and head. They are known for their ability to hibernate during cold seasons, curling up in nests made of leaves, grass, or other vegetation to conserve energy.

In summary, rats and hedgehogs are distinctive species with different physical and behavioral attributes. Their unique qualities should be considered when assessing their compatibility as potential cohabitants in a shared living environment.


Potential Challenges in Co-Living

Dietary Differences


Rats and hedgehogs have distinct dietary preferences to consider when planning to house them together. Rats are omnivorous, eating a balanced diet of grains, vegetables, and small amounts of protein.

Hedgehogs, being insectivores, primarily consume insects such as mealworms and crickets. To avoid conflicts, it is essential to provide separate feeding areas for each species and tailor their meals according to their unique dietary needs.


Temperature Control


The ideal living temperature differs between rats and hedgehogs, creating a challenge in creating a comfortable living environment for both species.

Rats thrive in a temperature range of 65-75°F (18-24°C), while hedgehogs require slightly warmer temperatures, between 75-80°F (24-27°C).

To maintain the ideal temperature for each animal, use heating pads or ceramic heat emitters and closely monitor the enclosure’s overall temperature.


Disease Control


One of the most significant concerns when housing rats and hedgehogs is the potential disease transmission.

Rats may carry communicable diseases and parasites that could harm hedgehogs, so it is essential to maintain strict hygiene practices to minimize the risk.

Regularly clean the enclosure, remove waste, conduct health checks on each animal, and schedule routine vet visits to ensure optimal health.

Additionally, consider using separate enclosures while still allowing them supervised social interaction opportunities.


Solutions for Successful Co-Living


Living together can be possible for rats and hedgehogs if specific co-living arrangements are made to ensure the health and safety of both animals. This section guides a successful co-living setup.

Separate Enclosure Recommendations

To minimize conflicts, both species should have completely separate living quarters. Provide hedgehogs with solid-bottomed enclosures containing hiding spaces and burrow areas. Use non-toxic, soft, and absorbent bedding.

Rats require separate cages with sufficient space for climbing and playing. A multi-level cage with different platforms and hiding spots is ideal.


Feeding Arrangements


Distinct feeding areas and specialized diets are crucial for rats and hedgehogs:

  • Hedgehogs: Feed them high-quality cat food containing at least 30% protein and 15% fat. Supplement their diet with insects, fruits, and vegetables.
  • Rats: Require high-quality rat food, preferably in pellet or block form. Fresh fruits, vegetables, and grains can be added to their diet.

Never allow one species to consume the other’s food, which can lead to health problems.


Veterinary Care Tips


Periodic veterinary care is an essential part of ensuring a successful co-living situation:

  1. Regular health check-ups: Schedule check-ups with a veterinarian experienced in treating small mammals to monitor their overall health.
  2. Vaccinations and parasite control: Consult a veterinarian for appropriate vaccines and parasite treatments to prevent illness.
  3. Quarantine new animals: If new rats or hedgehogs are introduced to the environment, quarantine them for at least two weeks before allowing interaction with established animals.

By following these recommendations and maintaining separate spaces and specialized care routines, it is possible to achieve co-living between rats and hedgehogs.



Rats and hedgehogs, although both small mammals have different natural habitats, behaviors, and dietary needs. These two species can coexist in the same living space, but their compatibility depends on several factors. For example, a large and well-ventilated enclosure with separate areas for sleep, exercise, and feeding can increase the likelihood of a peaceful coexistence.

However, it is essential to consider both animals’ individual temperaments and preferences when attempting to house them together. In some cases, rats and hedgehogs might show signs of aggression or stress, indicating that a shared living space might not be suitable for the well-being of either animal.

One primary concern when housing rats and hedgehogs is their differing sleep schedules. Rats are primarily nocturnal, while hedgehogs are typically crepuscular; this means they have peak activities at different times of the day. Providing separate sleeping areas and monitoring their interactions during their active periods can help reduce stress and potential conflict.

Regarding diet, rats and hedgehogs have incompatible nutritional requirements. Rats thrive on a diet of grains, fruits, and vegetables, while hedgehogs require a high-protein diet of insects. Offering separate feeding times can minimize the risk of competition for food.

Maintaining a clean and hygienic living space is crucial for both species, as they can suffer from various health issues if not correctly cared for. Regular cleaning and monitoring for any signs of illness in either animal can help ensure the health and happiness of both pets.

In conclusion, rats and hedgehogs can potentially live together, but doing so requires extra care, attention, and consideration to ensure the well-being of both animals. It is always recommended to consult a veterinarian or animal care specialist before introducing different species to one another.
