Best Pets for Small Apartments: Beyond Dogs and Cats

Living in a small apartment does not mean you have to go without the companionship of a pet. Millions of people around the world keep happy, healthy animals in compact living spaces — and the options go far beyond the obvious choices of dogs and cats.

Whether you are in a studio flat, a one-bedroom rental, or a modest city apartment, there is an animal companion that can fit your lifestyle, your space, and your budget. The key is matching the right species and breed to your living situation. Some animals need very little room. Others are virtually silent. A few barely need to be taken outside at all.

In this guide, we will walk through the best pets for small apartments — covering dogs and cats that genuinely suit compact living, as well as rabbits, guinea pigs, fish, reptiles, and birds. We will also address practical concerns like landlord restrictions, noise, exercise, and how to arrange pet sitting for less common animals when you travel.

Small Dog Breeds That Thrive in Apartments

Dogs are the most popular pets in the world, and many breeds do surprisingly well in small spaces. The secret is not about size alone — it is about energy level, noise, and adaptability.

Cavalier King Charles Spaniel

Cavaliers were bred to sit on royal laps, and they have never forgotten it. They are gentle, quiet, and perfectly content with a short daily walk followed by hours of lounging beside you on the couch. At 5 to 8 kilograms, they take up very little room and rarely bark without cause. Their calm temperament makes them one of the best apartment dogs you can find.

French Bulldog

Frenchies are compact, low-energy, and entertainingly lazy. They need a short walk each day and some play time, but they are not going to destroy your apartment out of boredom. They snore more than they bark, which your neighbours will appreciate. Just be mindful of their brachycephalic (flat-faced) anatomy — they overheat easily and should not be over-exercised.

Italian Greyhound

This one surprises people. Italian Greyhounds are slender, elegant, and remarkably calm indoors. They enjoy a good sprint in the park, but at home they curl up into a surprisingly small ball and sleep for most of the day. They weigh just 3 to 5 kilograms and are one of the quietest breeds you will encounter.

Shih Tzu

Originally bred as palace dogs for Chinese emperors, Shih Tzus were literally designed for indoor living. They are friendly, calm, and happy with moderate exercise. Their low-shedding coat is a bonus for apartment hygiene, though it does require regular grooming.

What Makes a Dog Apartment-Friendly?

It is worth restating: size is not the deciding factor. A tiny Jack Russell Terrier will cause more chaos in an apartment than a large, lazy Greyhound. The traits that matter most are:

• Low to moderate energy — A dog that is content with one or two walks per day.
• Quiet temperament — Excessive barking is the fastest way to upset neighbours and violate lease agreements.
• Adaptability — Dogs that handle routine noise, foot traffic, and confined spaces without anxiety.

If you are away during the day, a professional pet sitter can help with midday walks and companionship.

Indoor Cats: The Natural Apartment Pet

Cats are arguably the easiest traditional pet to keep in an apartment. They do not need to be walked, they groom themselves, and most are content with a window to watch the world go by.

Why Cats Suit Small Spaces

Cats are territorial, but their territory does not need to be large — it needs to be interesting. A well-designed apartment with vertical space (cat trees, shelves, window perches) can keep a cat just as stimulated as a house with a garden. Key considerations include:

• Vertical space matters more than floor space. A tall cat tree near a window gives your cat a lookout point, a scratching post, and a sleeping spot all in one.
• Indoor enrichment is essential. Puzzle feeders, rotating toys, and interactive play sessions prevent boredom and behavioural problems.
• Litter box placement is critical. In a small apartment, invest in a high-quality enclosed litter box with carbon filters to manage odour. The general rule is one litter box per cat, plus one extra — though in a studio, one well-maintained box can suffice for a single cat.

Best Cat Breeds for Apartments

While any cat can adapt to apartment living, some breeds are particularly well-suited:

• British Shorthair — Calm, independent, and not overly demanding of attention. They are happy to entertain themselves.
• Ragdoll — Laid-back, gentle, and famously relaxed. They tend to follow you around rather than climb the curtains.
• Scottish Fold — Quiet, adaptable, and known for their easygoing nature.
• Russian Blue — Reserved and independent, but affectionate with their owner. They are also one of the quietest breeds.

A Note on Adopting

You do not need a purebred cat for apartment living. Many mixed-breed cats from shelters are calm, adaptable, and perfectly suited to indoor life. Shelter staff can often advise on which cats have the right temperament for a small space.

Rabbits: Underrated Apartment Companions

Rabbits are one of the most overlooked apartment pets, and that is a shame. They are social, affectionate, and can be litter-trained just like cats. A well-cared-for rabbit can live eight to twelve years and form a deep bond with its owner.

Space Requirements

A single rabbit needs a minimum enclosure of about 1.5 by 0.6 metres, but they should not be confined all day. Rabbits need several hours of free-roaming time in a rabbit-proofed room or area. This means covering exposed cables, blocking gaps behind furniture, and removing anything you do not want chewed.

Why Rabbits Work in Apartments

• They are quiet. Rabbits do not bark, meow, or squawk. The loudest sound a rabbit typically makes is thumping its hind foot, which happens rarely.
• They can be litter-trained. Most rabbits naturally choose one corner for their business, making them easy to train.
• No outdoor access required. While some owners provide outdoor play time, it is not necessary. Indoor rabbits can live perfectly healthy lives.
• They are social and interactive. Rabbits recognise their owners, come when called, and enjoy being petted. They are far more engaging than many people expect.

Care Considerations

Rabbits need unlimited hay (timothy hay is the staple), fresh vegetables daily, and access to clean water. Their enclosure should be cleaned regularly — every two to three days at minimum. They also need veterinary care from a vet experienced with exotic animals, which can be harder to find and more expensive than standard dog or cat care.

Guinea Pigs: Social, Vocal, and Endlessly Charming

Guinea pigs are gentle, sociable, and full of personality. They communicate with a delightful range of squeaks, purrs, and whistles that most apartment neighbours will never hear through the walls.

Space Requirements

A pair of guinea pigs (they should always be kept in pairs or groups) needs an enclosure of at least 0.7 square metres. C&C (cubes and coroplast) cages are popular because they can be configured to fit awkward apartment spaces.

Why Guinea Pigs Work in Apartments

• They do not climb or escape. Unlike hamsters, guinea pigs stay where you put them.
• They are active during the day. No nocturnal wheel-spinning at three in the morning.
• They are low-allergen. While not truly hypoallergenic, they produce far fewer allergens than cats or dogs.
• They have manageable lifespans. At five to seven years, the commitment is significant but not overwhelming.

Care Considerations

Guinea pigs need vitamin C supplementation (they cannot produce it naturally), unlimited hay, fresh vegetables, and regular cage cleaning. Their social nature means you should commit to at least two — a single guinea pig can become depressed and unwell.

Fish: The Ultimate Low-Footprint Pet

If space is truly limited, an aquarium can bring life and beauty to even the smallest apartment without any noise, allergens, or landlord objections.

Best Setups for Small Apartments

• Betta fish — A single betta can thrive in a well-filtered tank of 20 litres or more. They are colourful, low-maintenance, and do not require a companion. Avoid the tiny unfiltered bowls — they are harmful to the fish.
• Nano community tanks — A planted 40 to 60 litre tank can house a small school of neon tetras, a few shrimp, and some snails. It becomes a living piece of art.
• Shrimp tanks — Cherry shrimp are fascinating to watch, breed readily, and can be kept in tanks as small as 20 litres.

Why Fish Work in Apartments

• No noise. A gentle filter hum is the only sound, and many people find it relaxing.
• No allergens. Perfect for renters with allergies.
• No landlord issues. Most landlords do not consider fish to be "pets" for lease purposes.
• Minimal space. A nano tank fits on a desk or bookshelf.

Care Considerations

Fish are low-maintenance but not no-maintenance. You will need to cycle the tank before adding fish, test water parameters regularly, perform weekly partial water changes, and avoid overfeeding. The initial setup cost for a quality small tank with filter, heater, and lighting runs between 80 and 200 euros, depending on your choices.

Reptiles: Quiet, Clean, and Surprisingly Low-Maintenance

Reptiles are gaining popularity as apartment pets, and for good reason. They are silent, they do not shed fur, they do not need to be walked, and many are perfectly happy in a modestly sized enclosure.

Leopard Geckos

Leopard geckos are arguably the best beginner reptile. They are docile, handleable, and live 15 to 20 years with proper care. A single leopard gecko needs a terrarium of about 60 by 40 centimetres — roughly the size of a large shoebox. They eat live insects (mealworms and crickets), require a heat mat for thermoregulation, and do not need UV lighting (though it is beneficial).

Corn Snakes

Corn snakes are gentle, manageable in size (around 1 to 1.5 metres as adults), and easy to care for. They eat frozen-thawed mice every one to two weeks, which some owners find more manageable than daily feeding. A corn snake needs a secure enclosure of about 90 by 45 centimetres with appropriate temperature gradients.

Bearded Dragons

Bearded dragons are social, handleable, and surprisingly personable for a reptile. They do require a larger enclosure (120 by 60 centimetres minimum) and UVB lighting, so they need a bit more space and setup than geckos or snakes. But their interactive nature makes them rewarding pets.

Why Reptiles Work in Apartments

• Completely silent. No barking, meowing, or squawking.
• No odour if maintained properly. Spot-clean the enclosure regularly and there is no smell.
• Feeding is infrequent. Some reptiles eat only once or twice a week.
• No fur or dander. Ideal for people with allergies.

Birds: Beautiful but Consider the Noise

Birds can be wonderful apartment pets, but noise is the unavoidable consideration. Some species are quiet enough for apartment living; others will get you evicted.

Apartment-Friendly Bird Species

• Budgerigars (budgies) — Small, cheerful, and relatively quiet. Their chatter is soft and melodic rather than shrill.
• Cockatiels — Friendly and interactive, with moderate noise levels. They whistle and sing rather than screech.
• Finches — Quiet, beautiful, and entertaining to watch. They do not need handling and are content in a well-sized flight cage.

Species to Avoid in Apartments

• Cockatoos — Extremely loud. Their screams can be heard several apartments away.
• Macaws — Beautiful but deafeningly loud.
• Conures — Can be unexpectedly noisy for their size.

Care Considerations

Birds need social interaction, mental stimulation, and a cage that allows them to spread their wings and fly short distances. Even "quiet" birds will make noise during dawn and dusk. Consider whether your walls are thick enough and your neighbours tolerant enough before committing.

What Landlords Actually Allow

One of the biggest challenges for apartment renters is pet restrictions in lease agreements. Understanding your rights and options is important:

• Dogs and cats are the most commonly restricted. Many landlords require a pet deposit, limit the number of animals, or ban specific breeds.
• Fish are almost universally allowed, as most lease agreements do not classify them as pets.
• Small caged animals (rabbits, guinea pigs, hamsters) often fall into a grey area. Some leases prohibit them; many do not mention them at all.
• Reptiles are sometimes explicitly banned due to perceived risk, even though a leopard gecko is about as dangerous as a houseplant.
• Birds may be restricted due to noise concerns.

Our advice: Always disclose your pet to your landlord, even if you think it falls outside the lease restrictions. Transparency builds trust and avoids disputes. If your lease says "no pets," negotiate — many landlords will make exceptions for quiet, contained animals with a reasonable pet deposit.

Noise Considerations in Apartments

Noise is the single biggest factor that determines whether a pet will work in an apartment setting. Here is a practical noise comparison:

If noise is a serious concern — thin walls, strict neighbours, or a lease with noise clauses — stick with fish, reptiles, or rabbits.

Exercise and Enrichment in Small Spaces

Every pet needs stimulation, even in a small apartment. Here is how to keep different animals enriched without needing a backyard:

Dogs

• Two daily walks of 20 to 40 minutes each (breed-dependent).
• Indoor puzzle toys and treat-dispensing balls.
• Training sessions — mental exercise tires a dog out faster than physical exercise.
• Consider a dog walker if you work long hours.

Cats

• Interactive play sessions with wand toys (15 minutes twice daily).
• Window perches for bird-watching.
• Puzzle feeders to slow down mealtimes.
• Rotating toys to prevent boredom.

Rabbits

• Several hours of free-roaming time daily in a rabbit-proofed space.
• Tunnels, cardboard boxes, and digging mats.
• Foraging toys that make them work for their food.

Small Animals and Reptiles

• Regularly rearrange enclosure furnishings to create novelty.
• Handling sessions for sociable species (guinea pigs, bearded dragons, corn snakes).
• Supervised out-of-enclosure exploration time.

Pet Sitting for Small and Exotic Pets

One concern that apartment pet owners often overlook is what happens when you travel. Finding a pet sitter for a dog or cat is straightforward, but what about a rabbit, a gecko, or a tank of tropical fish?

The good news is that many of these pets are actually easier to care for during your absence than dogs or cats:

• Fish need only feeding (which can be automated with a timer-based feeder) and water parameter checks. A pet sitter visiting every two to three days is usually sufficient.
• Reptiles may only need feeding once or twice during a week-long trip. A sitter needs clear instructions on temperatures, lighting schedules, and feeding protocols.
• Rabbits and guinea pigs need daily care — fresh hay, vegetables, water, and litter maintenance. A daily drop-in visit from a sitter works well.
• Birds need daily feeding, water changes, and social interaction. Some birds become stressed without company, so a sitter who spends time talking to them is ideal.

When booking a pet sitter on The Pet Sitter, you can specify the type of animal in your booking request and include detailed care instructions. Many sitters have experience with exotic and small animals — just check their profile for relevant experience.

Making the Decision: Which Pet Is Right for Your Apartment?

Choosing the right pet is a personal decision that depends on your lifestyle, your space, your schedule, and your budget. Here is a quick comparison to help you decide:

Frequently Asked Questions

What is the best pet for a studio apartment?

A cat is often the best choice for a studio apartment. Cats are independent, quiet, and do not need to go outside. If you prefer something smaller, a betta fish or a pair of leopard geckos are excellent low-footprint options. Rabbits can also work in studios if you can provide enough free-roaming time.

Can I keep a dog in a small apartment if I work full-time?

Yes, but you need to plan for it. Choose a low-energy breed, arrange for a midday walk (through a dog walking service or a helpful neighbour), and provide mental enrichment like puzzle toys. Dogs should not be left alone for more than four to six hours at a stretch.

Are rabbits really good apartment pets?

Absolutely. Rabbits are quiet, can be litter-trained, and form strong bonds with their owners. They do need several hours of free-roaming time daily and a commitment to regular veterinary care, but they are genuinely excellent apartment companions.

How do I find a pet sitter for exotic pets like reptiles or fish?

On The Pet Sitter, you can search for sitters in your area and check their profiles for experience with specific animal types. When you make a booking, include detailed care instructions covering feeding schedules, temperature requirements, and any health concerns. Many experienced sitters are comfortable caring for reptiles, fish, birds, and small mammals.

Final Thoughts

The best pet for your apartment is not necessarily the most popular one — it is the one that fits your space, your lifestyle, and your ability to provide proper care. A well-cared-for leopard gecko in a 60-centimetre terrarium is a happier animal than a border collie going stir-crazy in a studio flat.

Take the time to research, visit breeders or shelters, talk to current owners, and be honest about what you can offer. And when you travel, make sure your unusual companion is in good hands with a pet sitter who understands their needs.

Small space, big love. That is what apartment pet ownership is all about.
