Several questions, please ...
-1- What size is the cage? Dimensions ... wide? deep? tall?
-2- What chew toys does she have?
-3- How much "out of the cage time" does she have with you each day?
-4- Is she standing in the same place each time or in different places when she chews on the cage?
-5- What age is she?
I am getting so mad because no matter what I do she won't stop. And she just bit me when I tried to calm her down.
-6- How do you try to "calm her down"?
-7- Do you ever raise your voice at her?
-8- Have you ever slapped at, or hit her? (even by accident)
-9- How often do you clean her cage?
-10- What kind of bedding do you use?
-11- Have you changed laundry detergent/softener, room deodorizer, cleaned the carpen, changed perfumes, burnt sented candles or inscents?
-12- Did you change the location of her cage ... even by a little bit?
-13- Have you moved things around in the room she is in?
-14- Any new people/pets around?
Any of the above things/changes can stress a chinchilla.
You seem very stressed out ... chinchillas can sense this and it will stress them. If she does something that upsets her ... leave the room and don't even go back into the room until you have calmed down a bit. Anger and fear are two of the easiest things for an animal to be able to sense in you.
-15- Did she try to run away/hide, or fuss at you, or push your hand away before nipping you? If the answer is yes to anyone of these ... she was warning you to leave her alone, or she would bite you. Chinchillas rarely bite without reason or without warning ... since they can not talk in a human language ... you will need to try to figure out what she is upset at you about and not do it again.
Sudden or loud noises can stress a chinchilla and cause them to strike out in fear ... even if the sound is not in the immediate area.
They love a routine and needs to be in a regular routine (including out to the cage play time).
Always talk softly to them ... like you would a little baby.
