Chinchillas are sensitive eaters. They should never be given any fruits, vegetables, seeds, or nuts of any kind in any quantity, as can’t digest fatty or sugary substances. They thrive on unlimited access to a healthy pellet that is primarily made from hay (no forage), along with a handful of hay a few times a week and fresh water. No plastic, paper, or fabric other than anti-pill fleece in the cage. I would avoid google when it comes to learning about chinchillas. It gives a lot of false information and anyone can write an article on what to feed the precious babies.
I reccomend the following two Facebook groups as a place to post and ask questions
These are the only safe treats we recommend and the only ones will we ever sell.
