Unfortunately these sounds donšt keep away manmade objects which kill many ferrets each year. All ferrets suffer from problems such as being run over by vehicles, habitat destruction, being posioned, loss of food as well as many other reasons. Luckily there is only one species of ferret on the endangered list but that is still one too many. This species is the Black-Footed ferret. Along time ago there were many Black-Footed ferrets who loved to eat prairie dogs. One day the farmers decided that prairie dogs were pests so they poisoned their crops with a deadly chemical. This made many prairie dogs die. As the ferrets main diet was steadly depleting; many ferrets died of starvation. There are still very few prairie dogs, so there are not many Black-Footed ferrets left either.
