1. Clarification: The 2013 Guidelines make a distinction between euthanasia, humane killing, and slaughter, and state that neither slaughter nor humane killing is covered in the document P.68, S6.1.1. Not included among the definitions of these terms are ending the lives of healthy animals or scientific collection of animals. For clarification, whatever the term used, classification of the method, or reason given for killing animals: euthanasia, humane killing, slaughter, harvest, depopulation, scientific collection, or research-related, the Council on Accreditation’s foremost concern, in all situations, is with humane technique. The goal of humane technique is to minimize pain, distress, and the negative effect to the animal. The technique employed should result in rapid loss of consciousness followed by cardiac or respiratory arrest and, ultimately, a loss of brain function. Although complete absence of pain and distress is preferred, it is understood that it cannot always be achieved P7.13.2.

Guidelines for the treatment of animals in behavioural research and teaching

Captive animals may suffer if strongly motivated to perform activities that their housing does not allow. We investigated this experimentally for caged mink, and found that they would pay high costs to perform a range of natural behaviours, and release cortisol if their most preferred activity, swimming, was prevented.
Investigates the effect of limitations on caged mink. Popularity of fur farming; Research into the possible deprivation of mink, which result in their frustration; Details of the experiment; Impact of an access to water; Results which indicate that fur-farmed mink are still motivated to perform the same activities as their wild counterparts
