Does enriching your rabbit’s environment really change its behaviour?
Published by Planète Pets · managing editor: Clément Lacaille · how our guides are written
Tossing a few toys into an enclosure is often more of a reflex than an actual strategy. A study by Feng, Fan, Liang, Wang, Gao and Gun, published in 2022 in the journal PeerJ, compared rabbits housed in bare cages with rabbits given an enriched environment (gnawing materials, varied objects, room to explore) and measured both behaviour and several blood markers, including cortisol. Find all our enrichment guidance in the rabbit toys and enrichment section.

What did the study find about behaviour?
Enriched rabbits spent more time eating, drinking and exploring, and showed markedly fewer abnormal behaviours than rabbits in bare cages. This lines up with what we cover in our article on intelligence toys for rabbits, designed specifically to fill that exploration time.
What about physiological markers?
Blood cortisol, a stress-linked hormone, was significantly lower in enriched rabbits, while IGF-1, linked to growth and overall wellbeing, was higher. The study even found an effect on caecal flora, evidence that enrichment doesn't only touch visible behaviour but also the animal's internal physiology.
How to enrich an enclosure day to day?
Varying gnawing materials, hiding part of the ration to encourage foraging, and regularly rotating objects all prevent habituation. Our article on rabbits digging through litter to forage for food covers how to work with this natural behaviour rather than limiting it. Even a small enclosure benefits from this kind of rotation, since novelty itself, not the sheer number of objects, is what keeps a rabbit engaged.
- Behaviour: more time spent eating, drinking and exploring in an enriched environment.
- Cortisol: markedly lower in enriched rabbits, a sign of reduced stress.
- IGF-1: higher, linked to better overall condition.
- Practice: vary and rotate objects to avoid habituation.
Enriching a rabbit's environment isn't just a cosmetic nicety: it's a measurable lever on its stress and behaviour, one that shows up right down to its physiology.
Frequently asked questions
Does even a large cage need enrichment?
Yes, size alone doesn't replace variety: a large empty enclosure is still less stimulating than a more modest space well stocked with objects.
How many objects should be provided at once?
Two or three are usually enough if you rotate them regularly rather than piling them up permanently.
Does enrichment replace daily free-roam time?
No, it's a complement: supervised time out of the enclosure remains essential to a rabbit's wellbeing, and the two work best together rather than as substitutes for one another.
