* Oxygen Levels: High altitudes have significantly lower oxygen levels than sea level. Guinea pigs, being small mammals, have a higher metabolic rate and require more oxygen. They may experience respiratory distress, fatigue, and even death in extreme altitudes.
* Temperature Fluctuations: High altitude regions often experience large temperature swings between day and night. Guinea pigs are sensitive to cold and need a stable temperature to thrive.
* Pressure Changes: The lower air pressure at high altitudes can affect their internal organs and breathing.
* Limited Food Sources: High altitude environments often have limited vegetation and food sources suitable for guinea pigs.
Therefore, it's strongly recommended to keep guinea pigs at lower altitudes where they can get the oxygen and stable environment they need to stay healthy.
