I have a huge magnolia in our yard. It's old but not that old. I'd say more or less around 10 years old. It hasn't been sprayed with pesticide, ever. What parts of a magnolia tree are safe to a chinchilla? Does it have to be prepared properly? My chinchilla right now doesn't have any chews besides some pumice stones. It may be another week without any chews. She's been resorting to chewing her house because she's bored of the pumice.
