Why does your guinea pig go fluffy when it is eating certain foods eg cucumber?

It's not quite accurate to say guinea pigs go "fluffy" when they eat certain foods. They might appear fluffy, but it's more likely they're ruffling their fur as a response to enjoyment or excitement.

Here's why your guinea pig might be doing this:

* Excited for the food: Guinea pigs are very food-motivated and get excited about tasty treats. The excitement can manifest as a burst of energy, including fur ruffling.

* Sensory stimulation: The taste and texture of cucumber could be stimulating for your guinea pig, leading to a bit of a "happy dance" that includes fur ruffling.

* Grooming: While not directly related to food, guinea pigs often groom themselves after eating, which can fluff up their fur.

Important Note: It's essential to ensure your guinea pig is receiving a balanced diet with appropriate portions. While cucumbers can be a fun treat, they should not be a significant part of their diet. Overfeeding cucumbers can lead to digestive issues.

If you notice your guinea pig showing signs of distress, such as excessive fur ruffling, excessive grooming, or changes in behavior, consult with a veterinarian.
