Here's why:
* Digestive Issues: Cardboard is not digestible for guinea pigs. It can cause blockages in their digestive system, leading to serious health problems like impaction and even death.
* Toxicity: Some cardboard boxes may be treated with chemicals or inks that are toxic to guinea pigs.
* Lack of Nutrition: Cardboard offers no nutritional value for guinea pigs.
Instead of cardboard, provide your guinea pig with safe and nutritious options:
* Timothy Hay: This is the staple of a guinea pig's diet.
* Fresh Vegetables: Offer a variety of leafy greens, bell peppers, carrots, and other vegetables in moderation.
* Guinea Pig Pellets: These should be a small portion of their diet, providing essential vitamins and minerals.
Remember: Always supervise your guinea pig when they are interacting with any new materials, and ensure they have access to plenty of fresh water.
