Environmental enrichment: mirrors, music, toys, paper-based items and wooden objects

The literature suggests that mirrors may be useful to buffer isolation stress in some species. We do not really know if being forced to listen to loud music of the personnel's liking is also to the animals' liking. If it...

Environmental enrichment: Shelter and nesting material for rodents and rabbits; bedding for rodents

The needs for a shelter and nesting material of mice and rats are quite different. Building their own nests is almost a must for mice, and the nest will then also be used as a retreat. For rats, access to...

Capture of group-housed animals

Rats, mice and rabbits can be induced to come forward and be picked up by luring them with a food reward. Guinea pigs tend to be more timid but will run into a shelter in which they can then be...

The effect of housing rats in a stimulus rich versus stimulus poor environment on preference measured by sigmoid double demand curves

The present experiment investigated if the double demand curve method is sensitive to differences in housing conditions. We tested if rats performed more pressing when housed under barren compared to stimulating conditions, and if cross-points were ultimately affected. The experiment...

Massage-like stroking of rats

Massage is an ancient treatment that still is commonly used in humans. Massage is reported to have several beneficial effects including activation of the relaxation and growth response that is proposed to be mediated by oxytocin (OT). In the present...

A renewed look at laboratory rodent housing and management

In this article, recent publications are examined to determine the potential impact of new scientific evidence on current practices for the housing and care of laboratory rodents. The discussion points out recent advances in technology and new knowledge of the...

Environmental enrichment:Running wheels; burrows for rats and gerbils

Running wheels provide suitable enrichment rodents.The need to dig a burrow is probably not as strong in rats as it seems to be in mice. In sharp contrast to rats - who are very curious - mice are reluctant to...

Making use of the stress buffering influence of a companion: Post-operative care

We have mice who are recovering from telemetry-implantation while being housed either alone or in pairs. With several years of experience with this surgery, we now are pretty sure that socially housed mice feel better than individually housed mice.I can...

Feeding enrichment for mice, rats, guinea pigs, rabbits, cats and sheep

Feeding enrichment is a practical option for animals kept in research laboratories. The regular provision of thoroughly cleaned, whole fruits and vegetables and of seeds scattered on woodchips or corncob bedding is probably the easiest yet most effective way to...

Non-invasive measurement of adrenocortical activity in male and female rats

Rats are widely used in biomedical research as animal models for human diseases. However, due to their small body size, blood sampling is complicated and invasive and thereby can seriously interfere with endocrine functions and possibly compromise the animals' welfare....
