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. 

Nociception is the ability to encode and perceive harmful stimuli and allows for a rapid reflexive withdrawal. In some species, nociception might be accompanied by a pain experience, which is a negative feeling that allows...

Few studies have sought to describe cat elimination behavior in detail and much of the information presently available focuses on factors that potentially cause cats to reject a litter box. Thus, the ethograms published in...

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...

Cephalopods are the sole invertebrates included in the list of regulated species following the Directive 2010/63/EU. According to the Directive, achieving competence through adequate training is a requisite for people having a role in the...

This book summarizes the basic features of living fish. It is introduced by a chapter on the diversity of a group which has over 30,000 species, the largest within the vertebrates, describing the classification systems...

Positive reinforcement training with cats is a useful tool for improving the human-animal bond, treating behavior problems, and teaching novel tasks. In part 1 of this study, 3 cats were assessed for extinction to a...

This comment is in response to a recent review of stereotypical behavior in captive exotic animals (Rose et al., 2017). Negative stereotypical behavior occurs across most if not all taxa, including notable aquatic invertebrates. A...

There is a long-standing debate as to whether social or physical environmental aspects drive the evolution and development of cognitive abilities. Surprisingly few studies make use of developmental plasticity to compare the effects of these...

Honey bees (Apis mellifera) are prone to judge an ambiguous stimulus negatively if they had been agitated through shaking which simulates a predator attack. Such a cognitive bias has been suggested to reflect an internal...

Many pet cats are kept indoors for a variety of reasons (eg, safety, health, avoidance of wildlife predation) in conditions that are perhaps the least natural to them. Indoor housing has been associated with health...

Objectives: In search for methods of anesthesia of crustaceans, an implanted electrode into lobster and crayfish CNS enabled us to monitor signal propagation in the nerve system of animals undergoing different protocols. Results: Cooling (tap...

To determine the optimal electrical stunning conditions for edible crabs (Cancer pagurus) their impedance was investigated along with currents with the potential to render the animal insensible within 1 s. This information was used to...

Fasting is commonly used in aquaculture to empty the gut before slaughter, but little is known about how feeding frequency before fasting affects the stress response of trout. To find out more, 240 rainbow trout...

Cats are often subjected to minimally painful or forced procedures during routine clinical practice, which can be poorly tolerated, leading veterinary surgeons to need to offer physical restraint, usually aided by an assistant. The aim...

Arthropods have long been thought to respond to noxious stimuli by reflex reaction. One way of testing if this is true is to provide the animal with a way to avoid the stimulus but to...

Immune activation alters behaviour (i.e. sickness behaviour) in animals across phyla and is thought to aid recovery from infection. Hypotheses regarding the adaptive function of different sickness behaviours (e.g. decreased movement and appetite) include the...

For many animals, shelters are valuable source to hide from predators. To know acquisition of adequate shelter is important to understand social interactions of animals. Preferences for types of shelter used by the Marmorkrebs (marbled...

The domestic cat (Felis silvestris catus) originates from the solitary living African wildcat (Felis silvestris lybica). However, through domestication, the domestic cat has become more social towards conspecifics and group housing of cats is common...

The goal of the present study was to assess how cats react to tastes previously reported to be preferred or avoided relative to water. To this end, the facial and behavioral reactions of 13 cats...

Knowledge of the organization and dynamics of the relationships between animals and the environment and its resources is important to meet the needs of any species. We analyzed the effect the presence of a person...

Guidance is almost non-existent as to suitable levels of UV lighting for reptiles and amphibians, or how to achieve satisfactory UV gradients using artificial lighting. The UV-Tool is a working document that seeks to address...

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...

The European cuttlefish (Sepia officinalis) is often kept in public aquaria, is becoming more common in aquaculture, and is also the most frequently used cephalopod in European research. Since 1st January 2013, all cephalopods (Mollusca)...

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...

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...
