Lethargic and Drooling Chinchilla

So he is 7. He just had his teeth floated on May 12th. I know drooling means his teeth are overgrown but I had it taken care of already. He got home and was normal. Hopping, ate a little, acted normal. Well Tonight he is different. He isn't moving really at all. He is still drooling. Hasn't eaten all day. I gave him 0.2 mL of meloxidyl for pain as the vet told me to do tonight and last night. Can someone please help or point me in the right direction? Vet doesn't open till 7:30 am and I'm...
