Frost my regular BP has started squeaking lately. It will only be one loud squeak & then regular breathing. I have only heard him do it twice & they were a couple weeks apart. He hasn't shed in a while & his warm spot is at 90F & the cool side is at a tad over 80F. The humidity is finally up to 50% with a reptifogger going 15 mins every hour (he had a couple of bad sheds because the humidity in my house is so low & I didn't realize at first). Is it a respiratory infection or just some weird little noise he makes?
