Ok, so all of my temps are correct and most of the time my humidity is spot on (damn dry Vegas weather) and sometimes when I pick up either of the two balls I hear a faint hiss/wheeze. I can hear it only once in a while and there are no signs of mucus or any other symptom of RI and they both eat as soon as I offer a rat. Am I crazy or is this somewhat normal? Thanks for any help!
