Just received my 300 pinkies(200XS and 100Fuzzies) . I've never fed my Radixs these. I cut-up a few and mixed in a few worms. Gone in the blink of and eye. I then took one thawed XS and offered to one of my 6 month olds. He grabbed it and a few moments later it was gone. I haven't had to feed mice since my Bull snake became an educational snake for a local DNR(Dept. of Natural Resources) Now, it looks like I'll have a house full mousers. They really love them.
