What is a major health requirement for guinea pigs that is not a concern for other rodents?

Guinea pigs have a unique dietary requirement that distinguishes them from many other rodents: they must receive a regular intake of vitamin C. Unlike some animals that can synthesize their own vitamin C, guinea pigs lack the enzyme needed for this process, making them reliant on external sources. A deficiency in vitamin C can lead to serious health issues, including scurvy, which can manifest in symptoms such as lethargy, joint pain, and oral problems.

Regularly providing vitamin C is critical for maintaining their overall health and well-being, as it plays essential roles in collagen production, immune function, and overall cellular health. Including this vitamin in their diet through fresh fruits and vegetables or supplemented feed is essential to prevent deficiencies. This specific requirement underscores the importance of understanding and catering to the individual dietary needs of guinea pigs in contrast to other rodents, which do not share this particular necessity.
