Looks like a big enclosure compare to the size of your BP, which could have affect your BP over time.

I see one hide do you have another one identical?

Do you use anything else beside the dial gauge to measure your temps and humidity (those are not accurate and you need a digital thermometer/hygrometer)

Also remember 2 consecutive refusals are far from several month fasting, so try to identify what if there is anything that can be done so your BP resumes feeding.
