What is required in Animal Welfare Regulations for housing guinea pigs and/or hamsters?

Cages for hamsters must be at least 5 inches high is correct because it aligns with the Animal Welfare Regulations (AWR) that emphasize the importance of appropriate housing for the well-being of the animals. Providing a minimum height in cages is crucial to ensure sufficient space for hamsters to stand up, move around comfortably, and engage in natural behaviors.

The guidelines specifically outline standards for housing that cater to the physical and psychological needs of small mammals like hamsters. According to these regulations, the specified height helps prevent any potential injuries and promotes a better quality of life for the animals.

In contrast, while some might consider outdoor housing for hamsters or guinea pigs, it is generally not recommended as it can expose the animals to unpredictable environmental factors that might compromise their health and safety. Cages for guinea pigs being required to be at least 7 inches high, while there are standards for guinea pig housing, the specific rule regarding 7 inches isn’t directly cited in the AWR, making that option incorrect. Thus, focusing on the minimum height requirement for hamster enclosures is essential in meeting animal welfare standards.
