The primary difference is size and layout, as rabbits require significantly more vertical and horizontal space than guinea pigs. Rabbit hutches need to be at least 2ft tall to allow them to stand on their hind legs, while guinea pig enclosures focus more on floor space without the need for height. Additionally, guinea pigs do not navigate steep ramps well, so their hutches require single-level designs or very gentle inclines.

Rabbits need much more vertical space to stand upright (periscope), whereas guinea pigs require flat, single-level environments as they are poor climbers.

Designing for Different Species

Although they are often sold together in pet stores, rabbits and guinea pigs have very different housing requirements. A rabbit is large, athletic, and needs a minimum hutch height of 2 feet (60cm) just to stand up, plus massive floor space to stretch. Guinea pigs are ground-dwellers; they don’t jump or climb well. Therefore, a guinea pig hutch can be lower in height but still needs extensive floor area for running laps. If a guinea pig hutch has a second tier, the ramp must be wide, enclosed, and have a very shallow gradient to prevent spine injuries. Furthermore, guinea pigs are highly susceptible to cold and damp, meaning their hutches must be extremely well-insulated and often moved indoors during winter.

Frequently asked questions

Can rabbits and guinea pigs share the same hutch?

No, they should never be housed together. Rabbits can easily injure guinea pigs, and they carry bacteria (Bordetella) that is fatal to guinea pigs.

What is the minimum hutch size for two guinea pigs?

For two guinea pigs, a minimum floor space of 120cm x 60cm (4ft x 2ft) is recommended, though 5ft x 2ft or larger is significantly better for their welfare.
