Okay, so heres the accurate article, but I can't ignore this line "The plague affects both ferrets and their main prey: prairie dogs" WAIT, I'm honestly VERY unsure how to feel about this. I thought prairie dogs were bigger than ferrets. And I swear I thought ferrets are, like insects or something. I'm just really lost.

Haha prairie dogs are decently tiny. Some are smaller than squirrels I think. Maybe you're thinking of something else? And ferrets are from the same family as wolverines, weasels, Mongoose, and mink
