Environmental Enrichment

Environmental enrichment for a small colony of rats.

Our facility predominantly houses mice with a small number of rats used for brain cancer studies. Due to limited space and resource for equipment, we came up with some easy and cost effective ways to improve enrichment for the rat...

From Fish to Mice to Monkeys in Research: Challenges and Opportunities for Mental Well-being

This chapter focuses mainly on animals in medical research. Many, especially the smaller species such as rat, mice, and zebrafish, may be seen only a few minutes a day by their human caregivers. Most laboratory animals are kept in confinement...

Personality matters – The interplay between consistent individual differences and mouse welfare in female C57BL6/J mice

To ensure good welfare of animals in human hands, it is essential to modify housing conditions according to the animals’ needs. Traditionally, the effects of such modifications are studied by means of group-level comparisons, thereby widely neglecting consistent inter-individual differences...

Behavioral Biology of Laboratory Animals

This 30-chapter volume informs students and professionals about the behavioral biology of animals commonly housed in laboratory and other captive settings. Each species evolved under specific environmental conditions, resulting in unique behavioral patterns, many of which are maintained in captivity...

Playing music to animals: An interdisciplinary approach to improving our understanding of animals’ responses to music

Humans have profoundly changed the global soundscape. Studying how nonhuman animals respond to music can contribute to a better understanding of the effect of sound on animals. Animals are frequently exposed to human music, whether intentionally (for example, in laboratory...

Effects of species-relevant auditory stimuli on stress in cats exposed to novel environment

Environmental changes like vet visit could cause stress in cats. Studies have attempted to develop stress management strategies targeting sensory systems. Even though species-appropriate music which includes cat affiliative sound (e.g., cats’ purring and suckling sound) has been shown to...

Effect of feeding environmental enrichment on lesser anteaters’ behavior, space use and food selectivity

Studying behavioral response to management and housing conditions provides specific evidence to enhance animal welfare. Feeding environmental enrichment (FEE) is a powerful strategy to meet welfare challenges. Lesser anteaters’ (Tamandua tetradactyla; n = 7) response to FEE was assessed by...

The provision of browse and its impacts on the health and welfare of animals at the zoo: A review

Browsers are animals that consume significant proportions of leaves, twigs, and bark from woody plants. These species have evolved morphological, physiological, and behavioral adaptations to subsist on a specialized diet. In zoos and other managed care facilities, the provision of...

Sniffing for fun: Evaluating the effect of olfactory enrichment on cats’ toy preference and interaction

Play is a critical natural behavior in domestic cats. Toys and olfactory enrichment are common methods used to encourage play; however, no research has previously evaluated how olfactory enrichment affects toy interaction in cats. We hypothesized that the addition of...
