Here's why you might think they're yellow:
* Diet: A diet high in sugary treats and processed foods can lead to staining and discoloration of their teeth.
* Age: As chinchillas age, their teeth can become slightly discolored due to wear and tear.
* Dental problems: Dental issues like plaque buildup, tartar, or infections can cause yellowing.
Healthy chinchilla teeth are usually a pale, cream-colored shade. If you notice yellowing, it's important to consult with a veterinarian to rule out any underlying dental problems.
