Treats
Treats should be kept to a minimum. It is recommended that a chinchilla only have one treat per day. A suitable treat would be something like one raisin, one Craisin, one piece of banana chip, one small piece of dried papaya, one piece of unsweetened or lightly sweetened breakfast cereal (Cracklin’ Oat Bran is a favorite here), and things like that. An occasional sunflower seed would be ok but they are very high in fat and not recommended for chinchillas. It will not hurt to occasionally give more treats but the norm should be a maximum of one per night.
Also, it is not necessary and really not advisable to buy the little boxes/bags of treats in the pet store that are marketed for small animals. Those are overpriced, not always fresh (depending on the turnover in a particular store, and chinchillas love raisins or Craisins best. Dried fruits are cheaper in the grocery store.
Chinchillas generally live several years longer when they’re not overfed on treat foods. Something that you do not want to get is a salt block because chinchillas do not need the extra salt like rabbits do. To find online sources for treats, type CHINCHILLA TREATS in the search box on this page.
