Guys here is a little update on my situation. My girl ate on Saturday, however, without constricting. She missed the rat for the first time and then refused to attack him again, so I left it there and after some time she started eating. I was glad she ate, however, I am disappointed that she did not constrict. This is only 3rd time she has eaten since she has been with me (it's been over 2 months now and it seems like eating 3 times over more than 2 months is just so little food).
