Key points:
- Both guinea pigs and rabbits need more space than their small size might suggest.
- Hay should make up a major part of the diet for both species.
- Guinea pigs need dietary vitamin C because they can’t produce it themselves.
- Both are social animals and benefit from living with compatible companions of their own species.
- Guinea pigs and rabbits differ in their handling preferences and how they interact with people.
- Lifespan, space, daily care and local regulations should all factor into your decision.
If you’ve been considering a smaller pet, you might already be tossing up between a guinea pig or rabbit. Choosing the right one depends on the level of interaction you’re looking for, along with their space, diet, companionship and lifespan needs.
Read on for our guinea pig vs rabbit comparison, covering their housing, diet, lifespan and social needs to help you decide which could be the better fit.
Guinea pig vs rabbit enclosure and space needs
Small animals don’t necessarily need less space, and both guinea pigs and rabbits require a secure enclosure along with plenty of room to move and exercise.
If room is limited, consider an enclosure that makes good use of your available space, but prioritise enough usable floor area for your pets to move, stretch, explore and display natural behaviours. Guinea pigs need plenty of room to run and forage, while rabbits need enough space to run, jump and stand upright.
Both species also benefit from regular opportunities to explore outside their main sleeping area in a safe, secure environment. Rabbits in particular are highly active and need plenty of exercise space rather than relying on a hutch alone.
House-trained rabbits can learn to use a litter tray, making supervised indoor roaming easier. Just remember to rabbit-proof the area first, particularly around cables, furniture and anything else they may be tempted to nibble.
Before bringing your new pet home, find an exotic-pet vet nearby. Rabbits and guinea pigs have different health needs to cats and dogs, so having the right clinic lined up early can save stress later.
Guinea pig or rabbit: getting the diet right
Inside the enclosure, both species need access to suitable hay. Hay isn’t just useful for burrowing and enrichment – it’s an important part of both guinea pig and rabbit diets.
Beyond hay, guinea pigs and rabbits have different nutritional needs. Like humans, guinea pigs can’t make their own vitamin C, so it needs to come from their diet. A suitable guinea pig food, along with appropriate fresh vegetables, can help them get the vitamin C they need.
Rabbits can produce their own vitamin C, so they don’t need the same supplementation. Their diet should centre around grass and hay, with suitable vegetables and rabbit pellets offered as part of a balanced diet.
Lifespan of guinea pigs vs rabbits
Lifespan should always be a major consideration when choosing a pet, particularly if you’re adopting a younger animal. Rabbits can commonly live around 8 to 12 years with good care, while guinea pigs typically live around 5 to 7 years.
Both are a significant commitment, especially if you’re considering a small pet for a family with younger children.
How social each species is
Outside of care requirements, you’ll probably be particularly interested in how you’ll interact with your pet when weighing up whether to get a guinea pig or rabbit. Ultimately, they’re there to be a companion, and the right fit will look different for every household.
Both rabbits and guinea pigs are highly social. Guinea pigs should live with compatible guinea pigs, while rabbits are also best kept with compatible companions of their own species rather than alone. Rabbits and guinea pigs shouldn’t be housed together because their social, dietary and care needs differ.
Guinea pigs can live in compatible same-sex pairs or groups, or in appropriately desexed groups. They’re known for being vocal and communicative, often “wheeking” when they hear their owner approaching with food.
Rabbits are similarly social with their own kind and can also form close bonds with their owners over time. They communicate more subtly than guinea pigs, but you can expect behaviours like happy binky jumps when they’re feeling especially energetic.
How much handling they need
Handling and affection are major reasons we love having pets, but guinea pigs and rabbits can have different preferences.
Guinea pigs can become accustomed to gentle handling, particularly when introduced to it gradually, but being picked up isn’t naturally comfortable for every guinea pig. Always support their whole body and let their confidence build over time.
Rabbits often enjoy being petted but generally prefer interacting at ground level rather than being picked up. Approaching slowly, allowing them to come to you and respecting their boundaries can help build trust over time.
Should I get a guinea pig or a rabbit?
The rabbit and guinea pig comparison ultimately comes down to which animal’s needs best suit your household. Guinea pigs may appeal to people looking for a vocal, social small pet that can become comfortable with gentle handling.
Rabbits suit households with plenty of space to offer and owners who are comfortable with a longer commitment and a pet that often prefers interacting on the ground.
If children will be involved in their care, remember that both species are small and delicate, so handling should always be gentle and supervised.
One more thing to check before bringing home a rabbit: local regulations. Pet rabbits are prohibited in Queensland, and requirements may differ elsewhere, so always check the rules where you live before adopting.
