What must animals have in a primary enclosure setup?

In a primary enclosure setup, providing access to clean water and food is a fundamental requirement for animal health and welfare. Animals must have an adequate supply of fresh, uncontaminated water and appropriate food to meet their biological needs. This is essential for maintaining hydration, proper nutrition, and overall well-being. The importance of this aspect cannot be overstated, as it directly affects the physical health and vitality of the animals housed within the enclosure.

While elements such as natural foliage, entertainment devices, and social interaction can contribute positively to an animal's environment and psychological health, they are not strict requirements for primary enclosures. These other factors can enhance the quality of life for animals but are secondary to the basic needs for sustenance. Therefore, the focus on access to clean water and food is the foundational aspect that ensures animals can live healthy, thriving lives within their enclosures.
