Petted by a stranger: what a study reveals about rabbit stress
Published by Planète Pets · managing editor: Clément Lacaille · how our guides are written
Handing a rabbit over to a pet-sitter, or letting a visitor pet it, can seem harmless — the animal stays home, with no carrier or car trip involved. A study by Součková, Frühauf Kolářová, Přibylová, Kováčová and Zeman, published in 2026 in Frontiers in Veterinary Science, shows that mere contact with an unfamiliar person can be enough to trigger a measurable stress response. Our guides for planning a trip or arranging care are gathered in the rabbit travel and safety section.

Seven does, five petting sessions
The researchers exposed seven adult dwarf does to five ten-minute petting sessions, sitting on the lap of a person they did not know, mimicking a typical human-rabbit interaction during a visit or a boarding stay. Stress was measured both through salivary corticosterone levels and through behavioural indicators: ear position, eye openness, and body tension.
A cortisol rise of over 200%
Contact with an unfamiliar person caused an average rise of 214.4% (± 74.1%) in corticosterone levels, a statistically significant result. Behaviourally, the does showed ears pressed back, a tense body posture, and repeated eye closing — signs that, taken on their own, are often mistaken for relaxation, when here they reflected real, measurable discomfort.
What this means for boarding or a visit
A rabbit that looks "well-behaved" in a stranger's hands isn't necessarily having a calm experience: staying still is often a prey-animal strategy in a situation it can't control. Before a trip, our article on travelling with your rabbit or boarding it helps weigh the least stressful option, and our guide to preparing for a vet visit covers how to limit contact with unfamiliar staff.
- 7 does exposed to five ten-minute petting sessions by an unfamiliar person.
- +214.4% average salivary corticosterone after contact (p = 0.031).
- Ears pressed back, tense posture, closed eyes: stress signs correlated with the hormonal rise.
This finding doesn't mean all human contact should be avoided, but that a rabbit benefits from being introduced gradually to a new person, rather than handled straightaway as if by its usual owner.
Frequently asked questions
Is a rabbit that stays still during petting necessarily relaxed?
Not necessarily: the study shows stillness can coexist with a marked cortisol rise and subtle tension signs, such as pinned-back ears.
Should boarding with someone the rabbit doesn't know be avoided?
No, but letting the animal get gradually used to that person before departure reduces novelty-related stress, rather than immediate handling.
Does this finding apply to every rabbit the same way?
The study looked at adult dwarf does; individual sensitivity varies, but the principle that a stranger causes more stress than a familiar person carries over broadly.
