A guinea pig may have partial loss of appetite (inappetence) or refuse to eat altogether (anorexia). And while anorexia is mostly due to various forms of infections, inappetence is a common manifestation of several diseases and disorders, including lack of fresh water, an inability to chew properly, or exposure to extreme temperatures. Dietary changes and environmental changes may also trigger loss of appetite.
If a guinea pig does not eat for a long period of time, its condition may worsen quickly, resulting in liver problems and even death. Therefore, seek veterinary care if your guinea pig is suffering from either of these conditions.
The signs your guinea pig displays will depend on the underlying cause of its loss of appetite. Some common signs include:
If the loss of appetite is due to an infection, the guinea pig may have diarrhea or a fever. Meanwhile, misaligned teeth is a good indicator of malocclusion, another factor for loss of appetite.
Loss of appetite is frequently diagnosed by completing a thorough medical history of your guinea pig. To identify infectious-causing factors, however, your veterinarian will need to run various laboratory tests on the guinea pig.
