Shifts in naturalistic behaviors induced by early social isolation stress are associated with adult binge-like eating in female rats

Binge eating (BE) is a highly pervasive maladaptive coping strategy in response to severe early life stress such as emotional and social neglect. BE is described as repeated episodes of uncontrolled eating and is tightly linked with comorbid mental health...

A Retrospective Report of Carprofen Administration as Post-Operative Analgesia Reveals Negative Effects of Recommended Doses

Effective pain management in laboratory animals is crucial for both animal welfare and the reliability of scientific research. We retrospectively examined the effects of carprofen as post-operative analgesia in Sprague Dawley rats following stereotactic surgery. Our data indicate that administering...

Do we still need a canary in the coal mine for laboratory animal facilities? A systematic review of environmental health monitoring versus soiled bedding sentinels

Introduction Despite increasing evidence that Environmental Health Monitoring (EHM) is an effective method to perform rodent colony health surveillance, promotes the 3Rs as a Replacement, is comparable or reduces cost, and demonstrates labor benefits, many research institutions continue to use...

Rat tickling in gestation females

It has previously not been recommended to perform rat tickling on pregnant females. We questioned if rat tickling could be used for pregnant females to improve their welfare. After discussion with our veterinarians, Named Animal Care and Welfare Officer, and...

Specifically unspecific – Simple devices as feasible and effective enrichment for small mammals

Although enrichment is an essential part of modern zoo animal husbandry, research on effective enrichment for small mammals is scarce, albeit they are regularly kept in zoos. To develop solutions that are inexpensive, readily applicable, and adaptable for a variety...

Exploring pet rat care: A comprehensive survey of husbandry, health, behavior, and the associations between caretaker attitudes, attachment, and husbandry practices

Pet rats are still understudied in terms of animal welfare and human-animal interaction research. An extensive online survey targeting German-speaking rat caretakers was conducted (n = 978). One of the study's goals was to investigate husbandry practices, health indicators, rat...

Feel-good songs: Application of a novel playback paradigm to induce a positive affective state in juvenile male Wistar rats

Across animal welfare science there is a lack of validated models of positive affective states. Previous work has shown that presentation of contrastingly valenced ultrasonic vocalisations (USVs) to rats alters their behaviour. However, the potential of using playback of USVs...
