Can guinea pigs eat loofah?
Loofah isn’t for eating really as they won’t be able to break it off or digest it easily. It is more for playing with or gnawing so as to grind their teeth on it.
Guinea pigs may get frustrated with it as they won’t be able to eat it.
Loofah doesn’t break apart and stays together well.
You can purchase guinea pig toys that are made from loofah which many guinea pigs love to play with. They use them to toss around for the most part.
