Thank you for your question. Unfortunately, in an adult guinea pig there is not true way to "age" them, unlike in horses and cattle where we can reliable determine an age based on teeth evaluation, in other species of animals we don't really have an accurate way to measure age. As pets become geriatric we may see changes such as whitening of hair, loss of some muscle mass, and things like cataracts forming.
