What should be considered when selecting caging systems for different species?

When selecting caging systems for different species, the size and weight of the species are crucial factors to consider. Animals come in various sizes and weights, which directly impact their space requirements and the design of their cages. For instance, larger animals may require more spacious enclosures that can accommodate their size, while smaller species might thrive in more compact cages. Additionally, a caging system must provide adequate vertical and horizontal space for movement, comfort, and normal behavioral activities, such as climbing or burrowing, which are essential for their well-being.

While factors such as the age of the animal, the researcher's preference, and climate conditions can play a role in caging decisions, they do not supersede the fundamental requirements dictated by the animal's size and weight. For example, a juvenile might require different space than an adult of the same species, but the fundamental consideration of size is always pivotal. Thus, understanding the specific needs linked to the size and weight of the species ensures that the animals are housed appropriately, promoting their health and welfare.
