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. 
Reinhardt, V. (ed.) 2020. It’s Okay to Cry - Discussions by the Laboratory Animal Refinement & Enrichment Forum [LAREF], Volume V. Animal Welfare Institute, Washington, DC.

This is the 5th volume of selected discussions that took place on the electronic Laboratory Animal Refinement & Enrichment Forum between February 2016 and December 2019. The forum was created in October 2002; it allows...

Acharya, R., Rault, J.-L. 2020. Risk factors for feather-damaging behavior in companion parrots: A social media study. Journal of Veterinary Behavior 40, 43-49.

Studies on the etiology of behavioral problems often involve interference in the animal's routine or reliance on owners' self-reports like surveys. Gathering data from videos posted on social media, a technique coined ‘video mining’, offers...

McGlone, J. J., Garcia, A., Thompson, W. G. et al. 2019. Maternal-neonatal pheromone/interomone added to cat litter improves litter box use and reduces aggression in pair-housed cats. Journal of Applied Animal Welfare Science 22(2), 127-138.

Introducing a new cat into a household with one or more resident cats can be a significant source of stress for the cats involved. These studies sought to determine if rabbit maternal-neonatal pheromone (2-methyl-2-butenal [2M2B])...

Costa, J. H. C., Cantor, M. C., Adderley, N. A. et al. 2019. Key animal welfare issues in commercially raised dairy calves: social environment, nutrition, and painful procedures. Canadian Journal of Animal Science 99(4), 649-660.

Dairy calf welfare concerns are growing and new evidence suggests that the early life environment influences appropriate physical, behavioral, and cognitive development lasting into adulthood. This review highlights key evidence for the impacts of housing...

Silva de Souza Matos, L., Palme, R., Silva Vasconcellos, A. 2017. Behavioural and hormonal effects of member replacement in captive groups of blue-fronted amazon parrots (Amazona aestiva). Behavioural Processes 138, 160-169.

Social species in captivity may face allostatic overload due to artificial grouping and other social constraints. In rescue centres, groups of psittacines are constantly mixed due to the arrival and/or release of individuals; this procedure...

Foster, S., Ijichi, C. 2017. The association between infrared thermal imagery of core eye temperature, personality, age and housing in cats. Applied Animal Behaviour Science 189, 79-84.

Understanding individual responses to stress is a key aspect of maintaining optimal animal welfare. This is especially important where animals are being kept in sub-optimal environments or where the species may not clearly demonstrate stress...

Williams, I., Hoppitt, W., Grant, R. 2017. The effect of auditory enrichment, rearing method and social environment on the behavior of zoo-housed psittacines (Aves: Psittaciformes); implications for welfare. Applied Animal Behaviour Science 186, 85-92.

The psychological and physiological effects of different genres of music are well documented in humans. These concepts have also been studied in kenneled dogs and some exotic animals, implying that animals may experience benefits similar...

Greenwell, P. J., Montrose, V. T. 2017. The gray matter: Prevention and reduction of abnormal behavior in companion gray parrots (Psittacus erithacus). Journal of Veterinary Behavior 20, 44-51.

Gray parrots (Psittacus erithacus) are popular companion birds, particularly noted for their ability to mimic human speech, their intelligence, and longevity. They are also prone to developing abnormal behaviors such as feather damaging behavior. This...

Bayne, K. A., Beaver, B. V., Mench, J. A. et al. 2015. Laboratory animal behavior. In: Laboratory Animal Medicine, 3rd edition. Fox, J. G., Anderson, L., Otto, G., et al. (eds). Elsevier, Inc., Amsterdam, NL. pp. 1617-1651.

The study of laboratory animal behavior has increased steadily over the last decade, with expanding emphasis on a variety of commonly used species. In the United States, this trend was initially focused on species for...

Reinhardt, V. (ed.) 2013. Compassion Makes a Difference - Discussions by the Laboratory Animal Refinement & Enrichment Forum [LAREF], Volume III. Animal Welfare Institute, Washington, DC.

This is the third volume of discussions that took place on the Laboratory Animal Refinement & Enrichment Forum (LAREF). This forum is dedicated to the exchange of personal experiences of refining the conditions under which...

Rehrig, A., DeMagistris, M., Callan, C. 2013. Refinements in laboratory cat management: While the humans are away, the cats will play! Laboratory Animal Science Professional 1(4) (December), 32-35.

Cats can be successfully housed in groups when given enough space in addition to sufficient feeding, elimination, and resting areas. Cats at the University of Rochester are utilized in vision research, and have titanium cranium...

Poe, E., Hope, K. 2000. Group housing products for cats. Lab Animal 29(4), 40-43.

Commercial caging systems for cats are described and recommendations made for cat-appropriate housing. By housing cats in groups and with appropriate enrichments, according to their physical and psychological needs, researchers can decrease the animal's stress...
