I guess I hadn't read that part about the periodic parasite treatments.
That seems very unappealing to me.
There is that story about the Chinese doctor who was asked to participate in an asthma study. He said the way to treat these patients was to stop inducing the asthma.
I would not give anything to my animals with a plan to treat them later for possible fallout.
But I do wish I could offer my snakes the occasional amphibian without worry. Since I can't, I don't.
I have no desire to raise feeder frogs, but I do often wish, someone would.
