Hi.
My sweet Romans makes a clicking sound when breathing. I used to have pet rats. They made this sound when they had mycoplasma problems. I have no vet nearby that will see him to see if it can be treated. I'm afraid his life is being cut short. He does not act sick, except for sleeping a lot. But I think that is boredom. He has free roam of my bedroom which has been made safe.
Thank you in advance for any advice. I am in the Kansas City area if that helps.
