What great info! (in case y'all didn't already know that. )
I do have a question about Co2 concentration in the feeders' lungs/blood etc.
How long (if at all) after euthanizing the feeders should one wait before feeding?
Does the Co2 level in the feeders effect the animals (predator) at all?

(off topic a bit here)
I feed *all* my carnivores a species appropriate raw diet, that includes my cat and my dog when I had her. Raising our own feeders is something that my husband and I *do* plan on doing when we can. Seeing as how I do have snakes (and large inverts who get the occasional pinky mouse treat) who need to be fed, along with the mammals, I wouldn't want to adversely effect them from the Co2.

Sorry if it's a dumb question but...how else am I going to learn, yeah?
