I noticed a couple days ago that my female Chinchillas was kind of throwing up. She seemed to be collected saliva on her hands, but it didn't look like actual throw up. Now, I see that she hasn't been eating much dry food, although she'll still nibble on her raisins. She's now doing a motion where she pulls back her ears and it almost looks like she's raising her head and pulling back the corners of her mouth. (Almost reminds me of a cat hacking up a hairball.) She doesn't seem to be having any difficulty breathing and she's running around normally. Could this be a serious problem?
