Over 500,000 fish and 9,000 amphibians were used in the UK in 2016.<ref name=UK2017>{{cite web|url=https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/724611/annual-statistics-scientific-procedures-living-animals-2017.pdf |title=Statistics of Scientific Procedures on Living Animals, Great Britain|year= 2017|work= UK Home Office |access-date=2018-07-23}}</ref> The main species used is the zebrafish, ''[[Danio rerio]]'', which are translucent during their embryonic stage, and the African clawed frog, ''[[Xenopus laevis]]''. Over 20,000 rabbits were used for animal testing in the UK in 2004.<ref name=HomeOffice2004>{{cite web|url=http://www.official-documents.gov.uk/document/cm67/6713/6713.pdf |title=Statistics of Scientific Procedures on Living Animals, Great Britain|year= 2004|work= British government |access-date=2012-07-13}}</ref> [[Albino]] rabbits are used in eye irritancy tests ([[Draize test]]) because rabbits have less tear flow than other animals, and the lack of eye pigment in albinos make the effects easier to visualize. The numbers of rabbits used for this purpose has fallen substantially over the past two decades. In 1996, there were 3,693 procedures on rabbits for eye irritation in the UK,<ref>Statistics of Scientific Procedures on Living Animals, Great Britain, 1996 – UK Home Office, Table 13</ref> and in 2017 this number was just 63.<ref name=UK2017 /> Rabbits are also frequently used for the production of polyclonal antibodies.

Cats are most commonly used in neurological research. In 2016, 18,898 cats were used in the United States alone,<ref name=USDA2016 /> around a third of which were used in experiments which have the potential to cause "pain and/or distress"<ref>{{cite web|url=https://www.aphis.usda.gov/animal_welfare/downloads/reports/Annual-Report-Animal-Usage-by-FY2016.pdf|title=Annual Report Animals|publisher=Aphis.usda.gov|access-date=2017-08-06|archive-date=23 November 2020|archive-url=https://web.archive.org/web/20201123182104/https://www.aphis.usda.gov/animal_welfare/downloads/reports/Annual-Report-Animal-Usage-by-FY2016.pdf|url-status=dead}}</ref> though only 0.1% of cat experiments involved potential pain which was not relieved by anesthetics/analgesics. In the UK, just 198 procedures were carried out on cats in 2017. The number has been around 200 for most of the last decade.<ref name=UK2017/>
