What ambient temperature is too cold for them?

i had the same enclosure, and mine also wouldnt eat. What i did was just tape some dark paper around 3 sides of the enclosure, to make the whole thing into a hide, and that seemed to solve the issue. That being said i think the ambient temp could be a bit higher.

The temps seem fine to me, but how are you measuring the temps inside the tank because I don't believe that model thermo-hygrometer has a probe to read it from outside the tank. I would also start looking into a slightly larger enclosure now while you have a few months to do so.

Hey guys! My girl finally ate a f/t mouse. I have done the following tricks.
1. Cover the cage with black paper in daytime
2. Feed in a dark room
3. Feed at night
4. Try a 15gram mouse instead of a 20gram one
5. Today is warm and the ambient temp is 23-24 degree celcius
6. Dip the head of the mouse in VERY HOT water and offer to her immediately

I think feeding in a dark room is really effective and the major reason my girl won't eat is being too stressful. Thanks you guys very much!
