So I got this new female normal last weekend at the show, and she will not feed for me. Tried two days ago, she was stressed and didnt take it. Actually got very irritated and hissed at it quite loudly. Tried again today, she struck a total of four times, all of which didnt even touch the rat, and then proceeded to hiss like before. What should I do? Wait another week and try again to no avail? I just dont understand why she would hiss like that. Also, the rat was f/t, not live. Any suggestions?
