Yes I put the rat in a baggie when I thaw it. And the tank stays around 86-89 on the warmer side of the tank, it's a little cooler on the other end so she does have a temperature gradient.

And I think this week I will try with the hot tap water instead of boiling water, maybe the rat is a little to hot for her? I'm just confused mostly as to why she ate the first week but she hasn't eaten since.
