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...

Environmental enrichment for ferrets, guinea pigs and rabbits

You do not have to spend a lot of money to make ferrets happy. Empty bedding bags were a great hit! They also enjoyed rolling around small cat balls with bells in them, though they destroyed them rapidly and, hence,...

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...

Maladaptive behaviors: Stereotypical behavior; hair pulling-and-eating and alopecia (hair loss); self-injurious biting

Animals kept in legally minimum-sized, unstructured enclosures very often exhibit stereotypical behaviors. Traditionally, these repetitive movement patterns without obvious goals or functions are categorized as abnormal. A healthy animal kept in a small, barren enclosure has little choice of expressing...

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...

Enforced restraint of rodents: A discussion by the Refinement & Enrichment Forum

The question was asked: "Rodents are often restrained for data collection procedures, such as blood collection and injection, by coaxing them into tubes, for example syringe cylinders or perspex tubes. What can be done to buffer the stress response of...

Novel food items as environmental enrichment for rodents and rabbits

This column discusses the use of novel dietary supplements as environmental enrichment for rodents and rabbits. Items are commercially available from lab animal supply companies. The purpose of enrichment is to encourage behaviors that are appropriate for a particular species...

Social buffering of the stress response: Diversity, mechanisms, and functions

Protracted or repeated activation of the hypothalamic–pituitary–adrenocortical (HPA) system is associated with a variety of physical and psychological pathologies. Studies dating back to the 1970s have documented many cases in which the presence of a social companion can moderate HPA...
