Hey all, so I've only ever owned 1 rat before the rag I just recently bought the other day from the pet store. His started making these sounds and my last rat never made any sounds. The sound is hard to explain he doesn't do it all the time. I've recorded the sound via video but I can't attach it into this forum page. Id like some opinions before I go to the vet as I don't really have much money at the moment to see one.
