New BP owner here. Sorry if this question was posted before, I tried searching but couldn't find anything.

I got my girl about a month ago and she's about 5 months old now. When I got her the breeder told me she was eating live mice hoppers so I went to work switching her over to f/t. I was successful but she seemed to digest them quickly. She was active right after and the lump in her belly was gone within the day. Last Sunday I decided to try feeding her two hoppers at a time and she took them both. After that I didn't see her for two days lol. I've tried searching for frozen rats but there are never any available in the right size and she seems too small for bigger mice. So my question is, is it ok to feed her two mice at a time for now? Just until she gets a bit bigger and I can find rats in the right size?
