Physiological effects of environmental enrichment on BALB/c and C57BL/6 strain mice (2025)

Our aim was to assess the effects of enriched environment (EE) on some physiological variables, comparing BALB/c and C57BL/6 strain mice. Female BALB/c and C57BL/6 were individually housed under standard laboratory cages for 6 weeks and randomly separated into groups (n = 7...

What are the most prevalent welfare issues for pet small mammals? (2025)

The welfare of pet small mammals is an understudied, but growing research topic in the UK and Europe. We surveyed European veterinary experts who each rated severity and prevalence of a large number of issues in the eight most common...

Phenotypical, behavioral, and systemic hallmarks in end-point mouse scenarios (2025)

The state of frailty is a clinical–biological syndrome that affects the older population with a higher risk of functional dependence. Animal models can provide a tool to study this complex scenario. In the present work, we analyzed the physical and...

The calm mouse: An animal model of stress reduction

Chronic stress is associated with negative health outcomes and is linked with neuroendocrine changes, deleterious effects on innate and adaptive immunity, and central nervous system neuropathology. Although stress management is commonly advocated clinically, there is insufficient mechanistic understanding of how...

Burrowing behavior as robust parameter for early humane endpoint determination in murine models for pancreatic cancer (2025)

Due to late-stage diagnoses and limited treatment options, pancreatic cancer is predicted to be the second leading cause of cancer deaths by 2030. Many different murine models were developed over the past decades to test new therapies for this tumor...

The effects of handling on mouse behavior: cupped hands versus familiar or novel huts or tunnels (2025)

Mice are commonly tail-handled, despite evidence that this is aversive. Alternatives include cupping and tunnel handling; both methods are associated with improved welfare outcomes, including reduced anxiety and improved ease of handling, but tail handling may be perceived as more...

Understanding and mitigating male mouse aggression

We formed a global working group to identify the triggers of aggression e.g. behaviours seen prior to fighting occurring and have identified strategies to mitigate these triggers. We have also identified the signs of a harmonious cage, how to identify...

A systematic review of the effects of musical enrichment on captive mammals (2025)

Forty two studies examining physiological, behavioural and cognitive mammalian responses to music were identified, with 38.1% of those studies focusing on primates. The studies identified included 23 mammalian species across six animal orders (Artiodactyla, Carnivora, Perissodactyla, Primates, Proboscidea and Rodentia)....
