What is the difference between a ferret and a squirrel?

The ferret is a carnivorous (meat eating) mammal of genus Mustela of the Mustelidae family including the domestic ferret and an endangered species, the Black-footed Ferret. For hundreds of years, the main use of ferrets was for hunting, or ferreting. With their long, lean build and inquisitive nature, ferrets are very well equipped for getting down holes and chasing rodents and rabbits out of their burrows. Rodentia is an order of mammals also known as rodents. Rodents are food sources for ferrets. Rodents are omnivores, it eat seeds or plants, though some have more varied diets. Some species have historically been pests, damaging and eating crops and spreading diseases through their parasites and feces Members of non-rodent orders such as ferrets, weasels and mink are sometimes confused with rodents. If you mean: are rodents compared to ferrets?. Then the answer is NO. Ferrets are related to cats and dogs. Ferrets belong to the Mustelids. Weasels, ermine, otters and badgers are also Mustelids.
