Thank you for the warning Psychobunny. I'll definitely keep that in mind. That's why I was sorta hoping there would be a place I could buy them online like other feeders, but that doesn't appear to be very common.
For now I'll just stick with crickets and calciworms (which Lola loves as an occasional treat). I'm also attempting to give the calciworms enough time to morph into black soldier flies to try that as a treat for her, too.
