The difference between a black-footed ferret and a pet ferret is that Black-footed ferrets are the only ferret species native to North America and are a different species than ferrets kept as pets, which are from the European Polecat Ferret. The two ferrets are related along with the Siberian polecat ferret which lives in northern China and Mongolia. Black-footed ferrets physically differ from pet ferrets mostly in their fur. Black-footed ferrets always black feet, face mask and tail tip with a creamy/buff colored body. The fur on a black-footed ferret is shorter than that of pet ferrets, thus they look less fuzzy.
Ferrets coloring doesn't have anything to do with size. A ferret's gender makes a difference as females are always smaller than males. Unaltered ferrets are generally larger than altered ferrets. Ferrets that are in colder climates are larger than ferrets in mild climates.
In the UK ferrets cost between £5 - £10
