My chinchilla smells terrible!?

it could be maloclusion. its where the teeth grow wrong. its extremely dangerous and bad for a chin. they will drool all the time with maloclusion. sad thing is, maloclusion is sometimes a death sentence. i am sorry to tell you that. one way to help maloclusion is to take him to the vet and get his teeth clipped. the thing is, you would have to do this often, like once a month if i am not mistaken. i hope its not maloclusion. i hope its a simple problem that can be easily figured out and fixed. i wish you and your chinnie the best. good luck
