Just a quick little story I have a cinnamon male that had a whistling sound when he was breathing, i got scared and went straight to the vet, long story short she said my little cinny did not have RI and i should wait for the next shed to see if its still going on it stopped he is still eating and huge and as a matter of fact on november 1st hes going in with one of my females. But the bad news was it cost me 70 bucks but i got a fecal done and all that stuff. But it was a just a huge relief to hear it from a vet.
