Sleep preferences in CD1 mice in a laboratory environment

This study investigates the preferences of CD1 mice in a lab environment for various sleeping enrichment options within their cages. Understanding the environmental factors that influence sleep behaviour is crucial for enhancing animal welfare in laboratory settings. We assessed two...

Classical cuts: A pilot study of classical music’s effects on dogs in grooming settings

Grooming procedures are often stressful for dogs due to exposure to loud noises, unfamiliar individuals, and the absence of their owners. This study aimed to assess whether classical music could reduce stress-related behaviours in dogs during grooming. Fifteen companion dogs...

Marm-ite moments: Enriching marmoset behaviour with the 3Rs

It is well documented that activity levels of non-human primates (NHPs) are reduced in captivity, particularly in laboratory settings where space and enclosure design are limited.1 The 3Rs encourages researchers to refine their care of protected species by increasing the...

Chew sticks, do mice really care?

There are various chewing enrichments on the market for small rodents. In this study we focused on comparing two types, T-Brick and Aspen to see which product enabled more natural chewing behaviours in several strains of mice. A rack of...

An enrichment programme for group housed Rhesus macaques (Macaca mulatta)

The Centre for Macaques (CFM) houses Rhesus Macaques (Macaca mulatta) in groups of 2 to 18 individuals with ages ranging from birth to 16 years. We strive to create a comprehensive enrichment program with a variety of diverse types catering...

Environmental enrichment for laboratory rats and mice: Endocrine, physiological, and behavioral benefits of meeting rodents’ biological needs

Standard housing for laboratory rodents is characterized by cages that do not always provide an adequate environment to meet the animal’s behavioral needs. When animals are reared under impoverished conditions, negative states such as boredom and distress might arise. Environmental...

Rat boredom-like behaviour in a monotonous versus a varied foraging task: Effects of sensory variation

Evidence increasingly reveals that non-human animals in monotonous situations can show boredom-like states, distinctively manifesting as increases in both arousal-seeking, restless behaviour and low arousal, drowsy behaviour. However, task related boredom has been little investigated in animals, but could have...

Physiological and behavioral responses of stabled horses (Equus caballus) to three types of environmental enrichment

Small stalls and regulated feedings restrict horses’ natural foraging and locomotion, increasing risks to welfare. Environmental enrichment may promote more naturalistic behavioral time budgets, yet little is known about how enrichment type or timing affects physiology and behavior. This study...

A study into viable wooden enrichment objects for Syrian Hamsters

It is known that due to the continual growth of their teeth, hamsters require a means by which to wear down their teeth and satisfy their natural desire to chew. Due to their foraging behaviour hamsters use their cheek pouches...

Confronting crunching: A refinement for the care of mice with the desire to crunch

‘Crunching’ is the term often used to describe the abnormal behaviour of mice that habitually crunch their pelleted diet, causing substrate levels to rise as the crumbs settle on the cage floor ultimately burying the nest. The aim was to...
