Do chinchillas gain weight/fur for the winter?

[Fergggie]

I keep my chin inside so I wouldn't think the temp changes too much inside... But he seems to be getting fat! I haven't been feeding him more than I normally do but he seems bigger. He chews on his fur and its finally grown back completely so maybe that could be it? I was just wondering if maybe chinchillas know to eat more for the colder months because of instincts. I live in Indiana so the weather does get cold. Thanks I hope this doesn't seem like a stupid question!

No such thing as a stupid question - Actually the only stupid question is the one NOT asked. I have found that my chins eat more in the winter and definitely grow more coat in the winter even though the temperatures are regulated by me.

Wally always molts in the summer- I find fur everywhere- so he probably grows a coat in the winter too
