Thank you to the previous two posters! I have struggled a lot with the humidity. Is that what could have caused the RI if that's what she has? I bought a light dimmer for the UTH and set it so it's about 96 on the laser gun with substrate over it, it's about 89,90. I'll try to get her some more humidity and check out the top too. I started to use foil last night which has helped get the temps up a little. 82 cool side and 90 reading on the digital thermometer. Laser gun reads higher on the substrate directly under the ceramic bulb which is towards the warm side. Still can't seem to get humidity to hold over 37% or so hours after a mist.
Hopeing the vet Tuesday thinks it's an early stage of RI. No mucus today or bubbles. But she opens her mouth a lot and is defintely making sounds when breathing.
