I got my very first chinchilla from a pet store, and after that I ended up getting two more. Soon after though, one of them died from what I suspected is Malo, it had all of the tell-tale signs: Drooling, lethargic, and watery eyes. I didn't know how bad pet store chins could be when I got them, but now that I know I worry my other two pet store chins will end up with Malocclusion also. This scares me. They were from the same petstore also. Is there a way to prevent it? Or cure it before it happens?
