Compare two small pets
Torn between two small pets — or want to see how they really stack up? Pick any two and compare what matters for keeping them well, side by side. Every fact comes from our fact-checked care sheets.
| 🐹 Guinea Pig | 🐇 Rabbit | |
|---|---|---|
| Difficulty | Beginner | Beginner–Intermediate |
| Adult size | Adults weigh roughly 815–1,000 g (about 1.8–2.2 lb) and measure around 20–50 cm (8–19 in) nose-to-rump depending on breed — a solid, tail-less body built low to the ground. | Hugely breed-dependent: small breeds ~0.9–2.7 kg (2–6 lb, e.g. Netherland Dwarf, Mini Lop), medium ~2.7–4.1 kg, large ~4.1–5 kg, and giant breeds (Flemish Giant, French Lop) over 5 kg (11 lb+). Always check the adult size of your specific breed before you buy. |
| Lifespan | Typically 5–8 years — much longer than most rodents, so this is a real multi-year commitment, not a short one. | With a proper diet and good living conditions, 10–12 years or longer — some reach their mid-teens. This is a decade-plus commitment, not a short one. |
| Company | Guinea pigs are herd animals and must never be kept alone — in some countries it is even illegal to keep a solitary one. Good groupings include a neutered male with one or more females, two females, or brothers raised together (unrelated males can work but take patience). Any male kept with females must be neutered. Give every pig its own escape/hiding spots and enough food, water and shelter for all, so lower-ranking pigs aren’t bullied. If one must temporarily live alone, it needs daily human company as a stopgap. | Rabbits are social and should live with at least one other friendly, compatible rabbit — a neutered male paired with a neutered female is the classic bond, because neutering reduces fighting in both sexes. Give bonded rabbits both space to be together and space to get away from each other (as many hiding spots as rabbits, plus one). A rabbit that truly must live alone needs daily human interaction as a poor substitute for its own kind. |
| Housing | As much floor space as you can give, on a solid floor (never a grid or wire floor — it hurts their feet) with a good depth of litter. Guinea pigs run rather than climb, so floor area matters far more than height, though they need room to stand fully upright and youngsters need about 30 cm of headroom for their happy “popcorn” hops. Include a large exercise area plus secure shelters and hides — they feel exposed in open space — with as many hiding places as pigs, plus one. | For two medium rabbits, a living space no smaller than 3m × 2m × 1m high (about 10 × 6 × 3 ft), combining a secure shelter with an attached exercise area they can use whenever they like. They must be able to hop several times, stand fully upright on their back legs without their ears touching the roof, and stretch out flat. A traditional small hutch is not enough. Housing must be draught-free, dry, well-ventilated and predator-proof, with the shelter raised off the ground. |
| Temperature | Room temperatures of 17–20°C are ideal. Guinea pigs cope badly with temperature swings: above 26°C they risk heatstroke, and below 15°C they get chilled and should be moved indoors. Keep them out of direct sun, away from radiators, and free of draughts. | Comfortable in normal room or outdoor temperatures, but must be protected from damp, draughts and extremes of heat and cold — add shade over part of any run in warm, sunny weather. (A healthy rabbit’s own body temperature runs 39.4–40°C / 103–104°F; a reading below 38°C or above 40.6°C is a warning sign of illness — see a vet.) |
| Diet | Good-quality hay and/or grass makes up the majority of the diet and must be available at all times — it keeps the gut moving and wears down their continuously-growing teeth. Add a fresh daily portion of grass-based guinea-pig pellets and a daily variety of vitamin-C-rich fresh vegetables and herbs. Vitamin C is the make-or-break nutrient: guinea pigs can’t make or store their own, so it must come from the diet every day — and because vitamin C degrades in air, give a fresh portion of pellets and greens each day rather than topping up the bowl. Provide constant fresh water (check twice daily). Don’t overfeed pellets: too many (and too little hay) cause diarrhoea, bloating and gut disease. | About 85% good-quality hay and/or fresh grass — a bundle at least as big as the rabbit, available at all times, as it keeps both the gut moving and the continuously-growing teeth worn down. Add around 10% washed leafy greens and herbs daily (a large handful, ideally 5–6 different types such as kale, parsley, mint, dandelion), and only about 5% pellets — a small, measured daily amount, never topped up. Fruit and root veg (carrot, apple) are occasional treats only. Always provide fresh water. Never feed muesli-style mixes (they cause dental and gut disease), and never feed lawnmower clippings. Change any diet gradually over weeks — sudden changes cause dangerous gut upset. |
| Grooming | Guinea pigs rarely need bathing unless genuinely soiled (use a small-animal shampoo, never human shampoo, and dry thoroughly). Long-haired breeds need regular brushing to prevent painful matting. Check teeth and claws for overgrowth — a vet can trim them, but plenty of hay and gnaw items prevents most problems before they start. | Brush short-haired rabbits about twice a week and long-haired rabbits daily to remove loose fur; trim nails every 1–2 months as needed. Rabbits should never be declawed. In warm months, check the fur around their bottom daily — soiling and sticky droppings there can lead to deadly flystrike. |
Quick answers
How do I choose between two small pets?
Compare what decides whether you can keep it well, not just how cute it is: difficulty, adult size, lifespan, whether it must live with its own kind, the housing it needs, temperature sensitivity, diet, and grooming. A pet marketed as “easy” that lives 8+ years, needs a companion, or wants a huge cage is still a real commitment. This tool lays those side by side straight from our fact-checked care sheets.
Are guinea pigs or rabbits better for a family?
Both are social herbivores that must live with their own kind and need far more space than a pet-shop hutch — neither is a low-effort “starter” pet. Guinea pigs are ground-dwellers that need a daily source of vitamin C and rarely jump or bite; rabbits are larger, need even more room and a bonded rabbit friend, and many dislike being picked up. Choose by the space you have and how much handling everyone expects. Compare them above, then read both full guides.
Are the numbers in this tool reliable?
Yes — every figure comes straight from our species care sheets, each fact-checked against animal-welfare and veterinary authorities (RSPCA, PDSA, the Merck Veterinary Manual and peer-reviewed husbandry sources), so the comparison can never contradict the full care sheet. It is honest guidance to help you choose — not a substitute for reading the full guide or asking an exotics vet.
Can two different small-pet species live together?
No. Rabbits and guinea pigs, for example, should not share a home: they have different diets and body language, a rabbit can injure or bully a guinea pig, and they can pass on illness. Different species have different needs and stress each other. Use this tool to CHOOSE between species — keep each species with its own kind, not mixed.
