Straw is used for a lot of animals for bedding or food. It is very prevalent for farm animals for example. It is an agricultural by-product, the dry stalks of cereal plants, after the grain and chaff have been removed. It makes up around half the yield of cereal crops such as wheat, rye, rice, oats and barley. It is often used for fuel, livestock bedding and basket making.
So can chinchillas eat straw?
Yes they can, however the thinner, more dust-free is much better for them. Thicker staw may cause them harm as it can be prickly and hard. So if you are going to use it as a bedding make sure it is the thinner more biodegradable kind.
