No, chinchillas can’t eat sweetcorn. As this sweetcorn contains lot of acidic content this is not good for chinchilla. Especially the tummy of the chinchilla will get affect. They are rich in salt as the chinchilla can’t tolerate with it. Sweet corns are rich in oils and so some problems related to skin may occur. It also cause abdominal pain to the chinchilla. So not to feed sweetcorn to the chinchilla.
