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. 
Snowdon, C. T., Teie, D., Savage, M. 2015. Cats prefer species-appropriate music. Applied Animal Behaviour Science 166, 106-111.

Many studies have attempted to use music to influence the behavior of nonhuman animals; however, these studies have often led to conflicting outcomes. We have developed a theoretical framework that hypothesizes that in order for...

Rehnberg, L. K., Robert, K. A., Watson, S. J. et al. 2015. The effects of social interaction and environmental enrichment on the space use, behaviour and stress of owned housecats facing a novel environment. Applied Animal Behaviour Science 169, 51-61.

Every day, millions of domestic cats are held temporarily in captive environments, such as boarding catteries and rescue shelters. Being in confinement can potentially invoke high levels of stress for these animals. Therefore, there is...

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...

Arhant, C., Wogritsch, R., Troxler, J. 2015. Assessment of behavior and physical condition of shelter cats as animal-based indicators of welfare. Journal of Veterinary Behavior 10(5), 399-406.

Surveillance of cat shelters by official veterinarians in Austria is based on legal requirements and does not directly assess cat welfare. The aim of this study was to develop animal-based parameters that are feasible to...

Watson, C., Garman, K. A. 2014. Freebies for felines. American Association for Laboratory Animal Science [AALAS] Meeting Official Program, 573. (Abstract #P93).

Institutions are in a never-ending budget battle and items like environmental enrichment tend to get overshadowed. The challenge for laboratory animal technicians is to put on their thinking caps and find novel, low-cost enrichment items...

Nowlan, S. Y., Burlingame, L. A., Na, J. et al. 2014. Toys and technicians: 2 keys to a successful enrichment program for singly housed felines. American Association for Laboratory Animal Science [AALAS] Meeting Official Program, 583. (Abstract #P132).

Social or group housing is well known as the ideal environment for maintaining cats in a research setting as it allows specific behaviors such as play, grooming, and climbing. When social housing is not possible...

Damasceno, J., Genaro, G. 2014. Dynamics of the access of captive domestic cats to a feed environmental enrichment item. Applied Animal Behaviour Science 151, 67-74.

Providing feed enrichment to captive felids that are obligate carnivores is crucial for eliciting natural hunting behaviours. However, studies of the efficacy of enrichment techniques usually analyse the whole group, overlooking the different behaviours of...

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...

Savage, S. 2013. Kidding around in the laboratory animal facility - Goat enrichment. Enrichment Record 14, 14-15.

Goat enrichment can be incredibly rewarding, not only for the goat, but for personnel as well. In our facility, we often refer to goatenrichment tasks as technician (or vet!) enrichment. Somewhere in the evolutionary development...

Ellis, L. H., Wells, D. L. 2010. The influence of olfactory stimulation on the behaviour of cats housed in a rescue shelter. Applied Animal Behaviour Science 123(1-2), 56-62.

A wide variety of feline species have been shown to gain welfare benefits from the introduction of olfactory stimuli to the captive environment. The effect of this stimulation on the domestic cat, however, has been...

Brown, C. 2010. Organic wheatgrass as environmental enrichment. Lab Animal 39(3), 74-75.

Environmental enrichment must be provided for the various animal species that are housed in laboratory animal facilities. Wheatgrass can be used as a natural form of enrichment that requires minimal preparation and effort. Wheatgrass is...

Kry, K., Casey, R. 2007. The effect of hiding enrichment on stress levels and behaviour of domestic cats (Felis sylvestris catus) in a shelter setting and the implications for adoption potential. Animal Welfare 16(3), 375-383.

Results of this study suggest that the welfare of kennelled cats is greatly improved if they are provided with the opportunity to perform effective hiding behavior, and that the ability to perform such a behaviour...

Overall, K. L., Dyer, D. 2005. Enrichment strategies for laboratory animals form the viewpoint of clinical veterinary behavioral medicine: Emphasis on cats and dogs. ILAR Journal 46(2), 202-216.

Understanding the range of behaviors, behavioral choices, and cognitive stimulation that cats and dogs exhibit under non-laboratory conditions can increase the ability of investigators to predict which enrichments are likely to be the most successful...

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...
