Here's why:
* High acidity: Limes are very acidic, which can upset your guinea pig's digestive system.
* Potential for toxicity: Citric acid in limes can be toxic to guinea pigs in large quantities.
* Nutritional value: Limes don't offer any significant nutritional benefits for guinea pigs.
What to feed your guinea pig instead:
* Hay: Timothy hay is the most important part of a guinea pig's diet.
* Fresh vegetables: Offer a variety of leafy greens (dandelion, romaine lettuce, etc.) and other safe vegetables in moderation.
* Guinea pig pellets: Choose a high-quality pellet specifically formulated for guinea pigs.
* Fresh water: Always ensure your guinea pig has access to clean, fresh water.
Always consult a veterinarian before making any changes to your guinea pig's diet.
