Refinement Database

Database on Refinement of Housing, Husbandry, Care, and Use of Animals in Research

This database, created in 2000, is updated every four months with newly published scientific articles, books, and other publications related to improving or safeguarding the welfare of animals used in research.

Tips for using the database:

  • This landing page displays all of the publications in the database.
  • Use the drop-down menus to filter these publications by Animal Type, Setting, and/or Topic.
  • Clicking on a parent category (e.g., Rodent) will include publications relating to all the items in that category (e.g., Chinchilla, Gerbil, Guinea Pig, etc.).
  • You may also add a keyword to further narrow your search.
  • Please note that at this time, only publications dated 2010 or later (with some exceptions) can be filtered by Animal Type and Topic, and only publications dated 2020 or later (with some exceptions) can be filtered by Setting. Most publications older than 2010 can only be searched by keyword. 
Eyre, R., Trehiou, M., Marshall, E. et al. 2022. Aging cats prefer warm food. Journal of Veterinary Behavior 47, 86-92.

The aim of this study was to determine if meal temperature of cat wet food affected the feeding preference of aging (>7 years of age) domestic short-haired cats. We examined a chunks in gravy product...

Vanderzwalmen, M., Sánchez Lacalle, D., Tamilselvan, P. et al. 2022. The effect of substrate on water quality in ornamental fish tanks. Animals 12(19), 2679.

Almost all home aquaria contain substrate, either as intentional enrichment or for aesthetic purposes. For fishes, benefits of structural enrichment have been well considered, particularly in research and aquaculture settings. However, our understanding of the...

Powell, C., von Keyserlingk, M. A. G., Franks, B. 2021. Tank cleaning temporarily increases stress and decreases affiliative behavior in zebrafish. Applied Animal Behaviour Science 242, 105414.

Small, tropical fish are popular companion animals and constitute a major proportion of the vertebrates used in scientific research, but little is known about how they are affected by routine husbandry practices. Manual tank cleanings...

Delgado, M., Dantas, L. M. S. 2020. Feeding cats for optimal mental and behavioral well-being. Veterinary Clinics of North America: Small Animal Practice 50(5), 939-953.

In this article, we review cats' feeding behaviors, and discuss ways of feeding cats that promote physical and mental/behavioral health, while providing cats with choices that allow expression of preferences. We address the management of...

Villeneuve Beugnet, V., Beugnet, F. 2020. Field assessment in single-housed cats of litter box type (covered/uncovered) preferences for defecation. Journal of Veterinary Behavior 36, 65-69.

Cats living without any outdoor access have to use litter boxes to eliminate. A lack of cleanliness is one of the main reasons for which cat owners consult their veterinarian. What has been identified as...

Köbrunner, D., Waiblinger, S., Stetina, B. U. et al. 2020. Insight into husbandry conditions, health, and behavior of pet ferrets (Mustela putorius furo) among German-speaking ferret owners. Journal of Veterinary Behavior 37, 8-19.

Few data are published about different ferret husbandry practices in terms of housing, enrichment, feeding, social management, and the health status of ferrets. However, these factors are crucial for animal welfare and influence animal behavior...

McMahon, S. A., Wigham, E. 2020. ‘All Ears’: A questionnaire of 1516 owner perceptions of the mental abilities of pet rabbits, subsequent resource provision, and the effect on welfare. Animals 10(10), 1730.

Pet rabbit welfare is a hidden crisis: Inappropriately housed, fed, and not routinely provided healthcare—rabbits can often suffer painful conditions and shortened lifespans. This study provides novel understanding of owners’ perceptions of rabbits’ mental capabilities...

Naik, R., Witzel, A., Albright, J. D. et al. 2018. Pilot study evaluating the effect of feeding method on overall activity of neutered indoor pet cats. Journal of Veterinary Behavior 25, 9-13.

Indoor housing of cats is associated with a higher incidence of multiple diseases, including obesity. Increased exercise is often recommended as a method of creating or increasing the negative energy balance required for weight loss...

Villeneuve-Beugnet, V., Beugnet, F. 2018. Field assessment of cats' litter box substrate preferences. Journal of Veterinary Behavior 25, 65-70.

Cats living inside a home without any possibility of outdoor access have to defecate in a litter box. To suit the cats' needs, several recommendations seem to be agreed upon. The litter box has to...

Brown, C. 2015. Fish intelligence, sentience and ethics. Animal Cognition 18(1), 1–17.

Fish are one of the most highly utilised vertebrate taxa by humans; they are harvested from wild stocks as part of global fishing industries, grown under intensive aquaculture conditions, are the most common pet and...
