Monitoring an enrichment program: A pilot evaluation
The lack of useful information generated by a check sheet system suggests that we will need to make longer-term observations of animals in an enrichment program to adequately assess the merits of the program.

Read MoreThe effects of handling on antibody production, mitogen responses, spleen number, and lymphocyte subpopulations
The immune response was depressed when mice were picked up by the tail and held gently in the palm without restraint. From the methodological point of view, handling of experimental animals may be a significant uncontrolled factor in many in...

Read MoreAdverse effects in animals and their relevance to refining scientific procedures
The author highlights areas in which suffering can be prevented, alleviated and avoided. The terms pain, stress, eustress, distress and fear are clearly defined to help in determining animal suffering. One has to recognize suffering by non-verbal means, i.e. through...

Various hypotheses proposed for the function of urine marking in communication between male house mice were examined by comparing the predicted responses towards urine marks with those observed within eight captive territorial family groups. The responses of individual resident males...
