Operator
Operator: usagi Diary editorial team (independent)
Location: Japan
Since: 2021 (original usagi Diary app release)
Purpose of this site
We aim to provide a media that rabbit owners can rely on. Together with the usagi Diary app, we publish information that helps owners use daily observation as a trigger to notice small changes early.
Editorial team
Articles are currently written by the usagi Diary editorial team, based on publicly available books, professional organizations, and primary sources. We do not currently have per-article supervision by a veterinarian. For any medical decisions, please consult your exotic-animal-capable veterinarian.
We plan to partner with exotic-animal vets in the future and add supervisor names to health-category articles. When that happens, we will make the real name and title visible on this page and in each supervised article.
Information sources
Health-category articles reference primary sources such as:
- House Rabbit Society (rabbit.org)
- Rabbit Welfare Association & Fund (UK)
- Publicly available materials from Japanese veterinary and exotic-animal associations
- The textbook "うさぎの医学" (Rabbit Medicine) by Saito & Kakuno, Gakusosha
Specific references are listed at the bottom of each article.
