Rusty,
Thanks for your input. I appreciate the thought and effort you put into it. I do realize there is a limit to what I can do, and I am not looking to start a large-scale or multi-species rescue. When I move this summer, I expect to have a herp room for my snakes and places elsewhere in the house where I can house additional animals in isolation. I'd only consider taking in a couple of animals before then, or possibly a couple of groupings worth that came from the same initial location and could be expected to have already cross-contaminated and could therefore be housed in a shared rack (not shared cage).

I will not have access to a herp vet 24/7 as far as I can anticipate, but would have access to a vet tech at irregular hours and a vet during regular hours and would make use of that. That's not perfect, but better than most of the rescue animals are likely to have in the first place at least. I will check for local ordinances (and thank you for that reminder), but I'm pretty sure there is not a limit on bp's that I could house at once (though I can't have a single corn snake).

Thanks again for pointing out factors that should be considered by anyone thinking about starting a rescue, of whatever size and species.
