Description:  The Fisher, or as it is sometimes called, Fisher Cat, is a big weasel.  They average about three feet long, the tail is 13 to 16 inches long. The weigh as much as a big cat 5 to 12 pounds.

Habitat:  Fisher’s live in the northern mountainous parts of North America.  They prefer forested wilderness areas, although they will live near rural homes as well.

Diet:  When dining out, Fishers choose a restaurant with a good selection of rabbits and porcupines.  They will also hunt house cats and small dogs, so be careful letting your pets out if you live in a Fisher’s habitat.

Reproduction: Breeding usually occurs in early spring a few days after parturition. Following a gestation of approximately 353 days, a litter of one to five (average three) young are born. Within a week the female has mated again. The extremely long gestation is accounted for by the fact that fishers experience delayed implantation. The fertilized egg will remain inactive for a period of ten to eleven months before development resumes.  

Newborn young have very little fur covering them. The eyes open at about seven weeks of age. Young fishers remain in the den for about three months, after which they travel with the female until fall when the family breaks up.  Fishers have lived 10 years in the wild.

Trivia: 

In the early 20th century, fishers were trapped almost to extinction.  As a result, porcupine populations raged out of control and did considerable forest damage.  Always remember that every animal serves a purpose.
