Feeding (plz help)

[Alex Dew]

Hey all

I have had my bp for 2 months now. she is 1 1/2 ft.
4 weeks ago i offered her a med. mouse and she took it, then the week after she took 2 med. mouse,then the week after that she only took 1 and the week after that se oly took 1 again, which was 2 days ago. When she took her first strike at ir (2 days ago) she missed it and bit my finger and i bleed but after that i offered it to her again and she took it.
She can get 2 med. mouse down her to the middle of her body in about 15min.
I want to try and get her onto rats how shall i so this? is she big enough? how many rats and what size???

Thanks

Alex
