Holding my coral glow pastave last night while I was watching tv, and I swore I heard a faint whistling sound. My heart sank and I was convinced he had a RI! Turned tv off and listened real close but couldn稚 hear it again. Turned tv back up and the damn whistling sound came back! Turned tv completely off and held snakes head close to my ear, nothing. Sat there a second as still and as quiet as I could be when I realized it was coming from me!
