Abnormal/Problematic Behavior

A multimodal approach to treatment and management of rumination syndrome in a California sea lion (Zalophus californianus)

The management of chronic rumination syndrome in professionally cared-for animals requires a comprehensive and individualized approach. In this case study, a multimodal approach incorporating pharmacological treatment, feeding modifications, and behavioral management was applied to a California sea lion (Zalophus californianus)...

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...

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...

Evaluating the co-occurrence of abnormal behaviors in chimpanzees (Pan troglodytes)

For decades, welfare scientists have focused on investigating and mitigating the abnormal behaviors—including repetitive stereotypic behaviors and abnormal stances/postures—displayed by chimpanzees residing in professionally managed settings. In an effort to design feasible and practical welfare assessments, researchers often pool abnormal...

Meta-analysis on the effect of foraging on feather pecking and feather coverage

Feather pecking (FP) has been a longstanding concern in avian welfare because of its potential to inflict harm on bird plumage. Researchers have proposed the redirection hypothesis in studies investigating factors influencing FP, positing that pecking feathers serve as a...

Increasing cage complexity reduces abnormal behaviours in farmed blue foxes

We studied the long-term effects of biweekly rotated enrichment objects and a permanent shelter screen on abnormal behaviour, daily activity, and stress physiology in juvenile female blue foxes (aged 3–9 months). The experiment lasted seven months, from August to February, following...

Elastic motivation for circuit running behaviour in captive African striped mice Rhabdomys dilectus: A consumer demand approach

Captive environments often result in repetitive locomotor behaviours in animals, yet the motivation for these behaviours remains poorly understood. We investigated whether circuit running in African striped mice Rhabdomys dilectus represents a necessary coping mechanism or a flexible, cost-sensitive behaviour,...

Behavioral or nutritional drive: Which motivation affects rates of food grinding in CD1 mice?

Wire mouse feeders used in laboratory mouse cages typically hold enough food to feed 5 mice for two weeks. However, some mice gnaw the food provided into powder, which they do not ingest. The ground-up food fills the cage, resulting...

Investigating the motivations of repetitive barrier interactions in Pogona vitticeps

Considerable research has demonstrated that the effective management of repetitive behaviours such as bar-biting and pacing relies upon understanding their motivations; however, this same research has revealed that repetitive behaviours can have a diverse array of motivations. In reptiles, repetitive...
