Ferrets are carnivores and p-dogs are vegetarians, neither eat M&M’s that I know of. I believe chocolate is toxic to most animals.
I doubt it is toxic in the small amount contained in an M&M.
I do not know why both species (ferrets and prairie dogs) would be considered pests. Since the ferrets eat the prairie dogs, doesn’t that make them anti-pests?
What you say makes sense. Certainly sounded like a hair-brained idea to me. I’ll defer for now to the “experts” being taught in the same schools as other “experts” are graduating from. Lord help as all.
Canines, don’t know if chocolate is toxic to most. Though M&Ms strike me as an odd choice. If the prarie dogs die off, depriving ferrets of their protein, they’ll both become endangered, and the research into their diet will expand. Ground critters like that, I’d coat lettuce or beans with the vaccine.
