What do i feed my snake

[TardGirl]

I wanted to know if anyone had any ideas on what to feed my snake? She will not eat anything but gerbils, and they are alot of money and are hard to come by. She will not take prekilled food at all i have offered her many of times and never takes it. When she was little she got bitten by a mouse and would not eat them after that. And a few months ago she got bitten by a rat and now will not eat them at all. I thought that she would grow out of it or give in and eat after awhile but she went 8 months without eating cause she did not like what i was giving her. I went to PA. to vist family and while i was up there i went to a petstore and got 5 gerbils for 5 dollars. And she ate them all already now i have know idea what to do does anyone have any idea's?
