What is the Guinea Pig Temperament Quiz?
The Guinea Pig Temperament Quiz identifies likely temperament traits of guinea pigs from behavior-based answers. Behavior and compatibility mismatches are a common reason introductions go poorly or pets end up stressed, a little upfront assessment goes a long way.
Guinea pigs generally live 5-7 years when they are well looked after. Diet-wise they are a herbivore, which shapes almost every feeding decision you make. Guinea pigs are highly social and should never be kept alone. They need a large ground-level cage, unlimited grass hay, and a daily source of vitamin C. The usual suspects for this species are vitamin C deficiency (scurvy), dental malocclusion, respiratory infections, so any noticeable change is worth following up.

How does the Guinea Pig Temperament Quiz work?
The result comes from a weighted set of common, well-documented behavioral factors rather than a single yes/no rule, since real compatibility and temperament are rarely black and white. Individual guinea pigs vary more than averages suggest, so read the number as a reference point rather than a measurement.
What changes the answer
- Household composition: other pets, children, and general activity level all matter
- The individual animal's history and socialization, which can outweigh general breed or species tendencies
- Living environment: including space and access to outdoors
- Your own experience level and lifestyle, which affects how well a given temperament fits
How do you use the Guinea Pig Temperament Quiz?
- Pick your reaction to unfamiliar people (Hides or retreats, Watches from a distance, Curious and approaches, ...)
- Pick your reaction to being handled (Struggles or bites, Tolerates briefly, Relaxed, ...)
- Pick your reaction to sudden noise (Panics, takes a long time to settle, Startles then settles, Barely reacts)
- Pick your reaction to a change in routine (Stops eating or becomes withdrawn, Unsettled for a day or two, Adapts quickly)
- Press Calculate, then read the result alongside the sources listed below
Bring the number to your next appointment. Vets can work with a figure and a date far more easily than with "he seems a bit off lately".

Before you rely on this
One number on one day is rarely the full picture. What matters more is the direction of travel: whether your guinea pig is trending steadily, drifting, or changing suddenly. A sudden change is always worth a call to your vet, even when the individual figure still falls inside a normal range.
