Prey size for new 134 gram BP?

Like Deborah mentioned give your snake a regular mouse which should be just fine. My personal philosophy is that if you're not sure you can always feed your BP a smaller meal and make sure that it will take it. You can always go bigger on the next feeding day. Don't worry your snake won't starve ;)

I don't understand why people try to feed their snake the biggest meal possible... This isn't a race.

Wanted to update you guys.
I fed her for the first time yesterday evening and she ate fine. I used a small f/t mouse and left it in the tub with her (she had consumed it within 15 mins). The mouse seemed quite a bit small (it wasn't as wide as her body at the widest part), so I will try a small rat pup next time around and see how that goes.. I hope she will take one because I do not have any other sizes of mice on hand.

Thanks again for your help!
