Is a pop always a pop?

Yes, you just need to make sure not to push too hard, or you will create holes that shouldn't be..

Just ask someone to show you how who knows, and try a couple of times. It's not too bad.

Before I probed my corn snake for the first time, I must have watched the video on Kathy Love's site like a million times and read the instructions just as many times. It is scary the first few times you do it, but once you get a "feel" for it, it does become easier.
