I need some advice on feeding.

Oh yeah, the recent ones are great and very fine. I was really happy to see that change. It would be fine to use.

It's just knockoffs or other sources that may still have the sharper chunks and not the fine type. In that case, I would still be careful with snakes if like op they tend to drag and pick up bedding. Scratching up the mouth or esophagus might lead to food aversions or infection.

totally - if I’ve learned anything so far is that it pays to not cut corners

I never personally used or had an issue with a ground walnut shell product in the past, but I remember that many did- with internally injured animals from "razor-sharp edges" as a result. So I almost posted about that & thank Armiyana for doing so, especially with more personal experience on that. I went & looked up this current product also, & it appears to be little or no risk- but as mentioned, beware of "imitations". Companies try to provide economical products that make sense to them, but there's nothing like real-life animal experience to test for safety.
