When choosing a small mammal as a pet, apartment dwellers must consider space requirements, activity levels, and housing needs. While some species thrive in smaller environments, others demand more room to roam. Here’s a detailed look at the best small mammals for compact living and those better suited to spacious homes.

1. Hamsters

Hamsters are quintessential apartment pets. With their compact size and need for a well-equipped cage, they’re easy to accommodate. They’re nocturnal creatures, which means they’ll likely be active when you’re unwinding after work. However, they do need mental stimulation, so ensure their cage has wheels, tunnels, and chew toys. Regular cleaning is a must to prevent odor, and a quiet corner away from direct sunlight makes the perfect spot for their home. Their easygoing nature and minimal space requirements make them an excellent choice for small spaces.

2. Guinea Pigs

Guinea pigs are gentle, and social, and thrive in small spaces with the right setup. While they need a cage slightly larger than a hamster’s, they’re content with a cozy indoor space. Provide plenty of hay, veggies, and water, and interact with them daily to keep them happy. They also appreciate a playpen for occasional exploration, but their primary habitat can fit snugly into most apartments. Their sweet personalities and low noise levels make them ideal companions for apartment dwellers.

3. Gerbils

Gerbils are energetic but require minimal space, making them ideal for apartments. A tank with ample bedding for digging and tunnels for exploration will keep them entertained. Gerbils are low-maintenance and relatively odorless, but they’re social animals, so it’s best to keep them in pairs. With their minimal space requirements and cheerful demeanor, they’re a joy in small living quarters. Their natural burrowing behavior also provides endless entertainment for owners.

4. Mice

Small, curious, and easy to care for, mice are fantastic for limited spaces. They require a secure tank or cage with plenty of climbing structures and hiding spots. Mice are very active and enjoy exploring, but their habitat doesn’t take up much room. While they’re not always the cuddliest pets, watching their antics can be highly entertaining. With proper handling, mice can also become quite friendly and bond with their owners over time.

5. Rats

Rats might surprise you as apartment-friendly pets, but their intelligence and social nature make them delightful companions. They need a slightly larger cage with vertical space for climbing, but their habitat is still compact enough for most apartments. Rats love interacting with their owners and can even learn tricks, making them an engaging choice for small homes. Their playful and affectionate personalities often win over even the most skeptical pet owners.

6. Hedgehogs

These nocturnal little creatures are low-maintenance and need a simple enclosure to thrive. A large plastic bin or a small animal cage with a wheel for exercise works perfectly. Hedgehogs enjoy quiet spaces and require a warm environment, so keeping them indoors is ideal. Their solitary nature means they’re content without constant attention, making them perfect for busy apartment dwellers. With regular handling, they can also become quite tame and interactive.

7. Chinchillas

While chinchillas are larger than some other small mammals, they adapt well to apartment life with a vertical cage. They’re active and require dust baths and chew toys to stay healthy, but they’re quiet and relatively low-odor pets. Ensure their cage has multiple levels to satisfy their need for climbing and jumping. Chinchillas also thrive on routine, so keeping their environment stable is key to their happiness.

8. Dwarf Rabbits

Dwarf rabbits are compact and can thrive in apartments with the right care. They need a spacious cage and supervised playtime outside their enclosure daily. Provide chew toys and fresh vegetables, and they’ll be content in your cozy space. These friendly pets bond closely with their owners and bring plenty of charm to small homes. Their playful nature ensures they’ll keep you entertained, even in a smaller living area.

9. Sugar Gliders

Though exotic, sugar gliders are well-suited to apartments with a tall cage for climbing. These nocturnal animals form strong bonds with their owners and thrive with social interaction. While they require a specific diet and careful handling, their small size and playful nature make them a unique addition to any apartment. Their gliding abilities also add an element of wonder to owning them, as they dart gracefully between perches.

10. Ferrets

Ferrets are active and curious but surprisingly adaptable to apartment life. They need a multi-level cage and supervised playtime outside of it. Ferrets are mischievous and love to explore, so “ferret-proofing” your home is essential. With their playful personalities, they bring endless entertainment to small living spaces. Their intelligence also makes them highly trainable, adding to their appeal for dedicated pet owners.

11. Rabbits (Large Breeds)

While dwarf rabbits suit apartments, larger breeds like Flemish Giants need significantly more space. Their size and activity levels make them better suited to homes with large rooms or outdoor access. Even with an oversized cage, they require substantial room to stretch, hop, and play. Large breeds also have higher exercise needs, which can be challenging to meet in an apartment setting.

12. Squirrels

Squirrels are high-energy animals that demand extensive climbing space and outdoor time. They’re not ideal for apartments due to their need for trees and large enclosures. Despite their small size, their natural behaviors make them incompatible with confined living conditions. Their diet and care requirements also pose challenges for apartment dwellers.

13. Chipmunks

Like squirrels, chipmunks are active and need plenty of space to climb and forage. They’re not suited to small homes, as their habitats require elaborate setups to mimic their natural environment. Additionally, they thrive on outdoor exploration, which isn’t feasible in an apartment setting. Their high energy levels and skittish nature further complicate apartment living.

14. Prairie Dogs

These social animals live in burrows in the wild and need ample digging space and a large enclosure. Apartments simply can’t accommodate their complex housing and social needs. Prairie dogs are best suited to homes with outdoor areas or dedicated indoor rooms for their habitat. Without the ability to dig and socialize properly, they can become stressed and unhappy.

15. Groundhogs

Groundhogs are large and require vast amounts of space to dig and roam. They’re not domesticated and don’t adapt well to indoor living. Their natural behaviors make them unsuitable for apartments, as they thrive in open outdoor environments. Attempting to keep one in a small space can lead to frustration for both the animal and the owner.

16. Foxes

Even domesticated foxes need significant space to thrive. Their high energy levels and natural instincts for digging and roaming make them a poor fit for apartments. Foxes require secure outdoor enclosures and plenty of mental stimulation to stay healthy. Their curious and mischievous nature often leads to destruction in confined spaces.

17. Pot-Bellied Pigs

Though small for pigs, pot-bellied pigs need much more space than an apartment can provide. They’re highly intelligent and require outdoor access for rooting and exercise. Without proper space and stimulation, they can become destructive, making them a challenging choice for confined living spaces. Their loud vocalizations can also be disruptive in apartment buildings.

18. Raccoons

Raccoons are curious and highly active, demanding a significant amount of space and mental stimulation. They’re not suited to small enclosures or apartment living. Additionally, they’re notorious escape artists and need a secure, spacious environment to thrive. Their complex dietary needs and strong personalities make them a handful for any owner.

19. Skunks

Domesticated skunks require room to roam and explore, making apartments less than ideal. They’re curious animals that need enrichment and space to prevent boredom. Skunks also benefit from outdoor access, which is challenging in small living situations. Their specific care needs and unique behaviors make them better suited to larger homes.

20. Large Exotic Cats (e.g., Servals)

While some exotic cat enthusiasts keep servals in homes, their space and activity needs far exceed what apartments can offer. These animals require outdoor enclosures and ample room to roam, making them unsuitable for confined living conditions. Their predatory instincts and specialized care further add to the challenges of keeping them in a small space.
