Here's why:
* Ingestion Risk: Guinea pigs are prone to chewing and might ingest pieces of cardboard, which can cause digestive issues, blockages, and even death.
* Potential for Sharp Edges: Cardboard can have sharp edges that can cut or injure your guinea pig's mouth or digestive tract.
* Ink and Chemicals: Some cardboard tubes may be treated with inks, dyes, or chemicals that can be toxic to your guinea pig.
Safe Alternatives:
* Paper tubes: These are generally safer as long as they are made from plain, uncoated paper.
* Wooden chews: Hardwood chews like apple branches or willow branches are good options for gnawing and are safe for guinea pigs.
* Hay racks: Hay racks allow your guinea pig to enjoy their hay while preventing them from ingesting large amounts of cardboard.
* Enrichment items: Provide your guinea pig with plenty of safe and stimulating toys like tunnels, hay balls, and hideaways.
Always supervise your guinea pig when they are playing with any new toy or item.
