No, Guinea pigs cannot eat spinach stalks. Spinach stalks are fibrous and stringy, which makes them tough to swallow. Even human beings have problems eating those let alone our guinea pigs.

Also, remember to wash the spinach properly before serving as they might contain some harmful particles attached to them that can have an ill effect on guinea pigs.

Also, cooking involves adding salt, spices, cooking oil, or any other ingredients which are a complete No-No for guinea pigs.

Guinea pigs can suffer from serious digestive diseases as their digestive system is very delicate. So, serving them with good food is critical.
