Guinea Pig

The role of line-of-sight in operant experiments using food reinforcers in guinea pigs

The guinea pig (Cavia porcellus) is a species utilized as a model in laboratory science and is a popular companion animal. The study aimed to assess the role of line-of-sight with a food reinforcer in the ramp climbing behaviour of...

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...

Guinea pig (Cavia porcellus) welfare: Associations between husbandry practices, human–animal interactions, and animal behaviour (2025)

Research on the welfare of pet guinea pigs and connections between their behaviour and husbandry practices is scarce. Through an online survey among 1181 German-speaking guinea pig caretakers, we investigated husbandry practices (including social composition, housing type, free roaming, enrichment,...

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)....

Sedation efficacy of midazolam in conjunction with ketamine and alfaxalone in female laboratory guinea pigs (Cavia porcellus)

Guinea pigs have been integral as models used in biomedical research, making significant contributions to nutritional, auditory, immunologic, and hypersensitivity studies, and necessitating the routine need for sedation in laboratory settings. The ketamine-xylazine (KX) combination has been the standard sedation...

Effect of adopting a timothy hay–based diet at weaning or in adulthood on urinary tract parameters in strain 13/N guinea pigs (Cavia porcellus)

Type of feed is an important consideration in herbivore colony management, yet limited studies report on the effects of diet on common conditions such as urolithiasis in guinea pigs. Urolithiasis is a well-documented cause of lower urinary tract disease in...
