I purchased a CH(they told me CB) from a store once that was dehydrated, had mites and ticks. That snake was returned.

I have nothing against CH(I have several in my collection) but I only get them from reputable people/breeders/dealers not stores.

Most in stores have never fed and are housed in large groups. I prefer an animal that is established, eating and has been kept in correct husbandry conditions.
