yes sir! That's the method I use as well. I find this though.... my snake often won't eat prey that I have put in a ziplock bag... I have NO idea why but I believe the scent is to blame.. even we can smell new ziplocks right? So what I do now is , I went to the local grocery store and bought a pack of those disposable tupperware deals.. I think it was like three bucks for five (on sale) all I've ever needed was one, plus when you heat it up with the emitter you can just take off the lid of the tupperware and set the fixture on the top of the tupperware - no more burnt mousie hairs from the light being too close
