Study suggests rabbit pheromone may ease stress in new settings

A newly published study in Frontiers in Veterinary Science adds fresh evidence that rabbit appeasing pheromone may help rabbits adapt to unfamiliar environments. The paper, published August 13, 2026, found that rabbits treated with topical RAP behaved differently from placebo-treated controls during repeated open-field testing, showing patterns the authors interpreted as reduced anxiety-related responses and better acclimation to novelty.

The work builds on a broader push to improve rabbit welfare in situations that routinely challenge this prey species. In the paper’s introduction, the authors note that rabbits are especially sensitive to environmental stressors, including novel spaces, social isolation, and human handling. They also position the new trial as a follow-up to earlier RAP work in rabbits, including studies tied to veterinary procedures, transport, and a prior pilot study of topical use in a novel environment.

In the new study, 28 rabbits were randomly assigned to RAP or placebo groups, balanced for sex, neutering status, and parity. All were adult New Zealand White rabbits, 12 to 16 months old, and none had previously been exposed to the test arena. Researchers used a repeated open-field design over two consecutive days, measuring locomotion, exploration, grooming, and spatial use of the arena. Across both groups, behavior shifted from higher locomotion on day 1 to less movement and more stationary behavior on day 2, which fits a basic acclimation pattern. The treatment effect was most apparent in exploratory behavior: RAP-treated rabbits entered the central zone faster and spent more time there, and there was also a statistical tendency for them to enter the arena voluntarily sooner than controls.

The product studied was SecureBunny Adventure, a topical RAP cream from SIGNS Labs. That matters because the paper is not just testing the pheromone concept in the abstract, but a specific commercial delivery format intended for handling, exploration, and other situations where a diffuser or mist may be less practical. SIGNS Labs markets the SecureBunny line for new environments, transport, veterinary hospitalization, and other potentially stressful events, although those commercial claims go beyond what this single study can establish on its own.

Outside this paper, the supporting evidence base is still early but expanding. An Animals study published in 2024 reported that RAP helped rabbits cope with routine veterinary acts and vaccine-related stress, while a more recent transport study found that a mist formulation improved rabbits’ response to travel. Those studies, like the new Frontiers paper, came from the same broader research ecosystem around IRSEA and RAP development, so they’re useful context but not the same as broad independent replication.

Why it matters: Rabbit medicine still has fewer behavior-support tools backed by published data than canine or feline practice. For clinics trying to reduce stress during exams, hospitalization, transport, or boarding, RAP may be a useful adjunct to established low-stress handling, quiet housing, familiar scent cues, bonded-pair considerations, and careful environmental management. At the same time, veterinary teams should read the findings with appropriate caution: the study was small, used a controlled open-field model rather than a clinical setting, and included only one breed and age band. The authors themselves say larger studies are needed to confirm and strengthen the findings. (frontiersin.org)

There also appears to be a commercial runway forming around these findings. SIGNS Labs has positioned SecureBunny as a full rabbit pheromone range, including home, transport, and adventure formulations, and retail listings for the topical cream are already appearing in the market. For veterinarians, that means pet parents may start asking about RAP more often, especially for travel, introductions, hospitalization, or fear around handling. (securebysigns.com)

What to watch: The next important step is independent, real-world validation, especially in companion rabbit practice, shelter intake, transport, and peri-visit stress protocols, as well as clearer guidance on which formulation works best in which setting. (frontiersin.org)
