Yes, the vet diagnosed as RI. Our warm side was thermostat controlled at about 94-95* and we also used a heat gun to read the temps and they were rarely below 92* on the warm side. The cool side and ambient temps were low 70's at the time, which we did work to correct. Humidity hovered around 50%. I know now that our ambient temp was too low at the presentation of symptoms. We've completely corrected that with our new setup (ambient temp of 80*, warm side read 92* on the gun this morning).
