Here's a breakdown:
* Brushing: Guinea pigs sometimes shake when they're being brushed, particularly if they are sensitive to being touched.
* Cold: Guinea pigs are sensitive to cold temperatures and may shiver if they're too cold.
* Excitement: Some guinea pigs shake when they're excited, particularly if they are anticipating a treat or playtime.
* Stress: A guinea pig might shake if they are stressed or frightened, but it's not the only indicator. They might also exhibit other signs like hiding, teeth grinding, or rapid breathing.
* Medical Condition: Shaking can also be a symptom of a medical condition, such as neurological problems or infections.
If you notice your guinea pig shaking, it's important to observe their other behaviors and consult a veterinarian to rule out any underlying medical issues.
Here's a helpful guide to determining the reason:
* Is it a consistent shaking, or does it happen in specific situations?
* What other signs are they displaying?
* What's the temperature like in their environment?
By observing your guinea pig and understanding their behavior, you can help determine the reason for their shaking and provide appropriate care.
