Applesauce is that which is made from puréed apples. It can be concocted with peeled or unpeeled apples and using different spices such as allspice. You can also add flavourings and sweeteners such as honey or sugar to it. It is widely eaten in Europe, USA and UK.
So can chinchillas eat applesauce?
Unfortunately they cant at all. Applesauce is just too sweet for them and has too many preservatives and sweeteners for them. Even if it is preservative and sweetener free then the texture is just not what they like.
So it is a food to avoid as far as chinchillas are concerned.
