I adopted a vanilla female from Petsmart a week ago. At that point she wasn't eating for them for 3 weeks. Weighed in 343g, age unknown/presumably young.
Attempted to feed tonight after a full week of a complete non-disturbance -- no luck. Attempted to assist feed -- no luck.
I left her rat pup in the enclosure but I think I got her sufficiently pissed off for her to eat it... Weight 3 days ago -- 320g.
Also noticed that her snout was a bit rubbed but no wheezing was observed.
My next step?
The setup is to a T-- 80cold/91hot sides, 2 identical sides, crowded with vines, the sides are covered.
