Gray Fox

Kingdom:Animalia
Phylum:Chordata
Class:Mammalia
Order:Carnivora
Family:Canidae
Genus:Urocyon
Species:U. cinereoargenteus

 Description:The Gray Fox is one of the few species of fox that is not under the Vulpes genus, and instead under the Urocyon. This difference in genus is due to their genetic make-up being closer to that of the Asian Raccoon Dog and the African Bat-Eared Fox. The Gray Fox is one of the oldest known foxes as well, ranging all the way back to the Pliocene Era, approximately 3.6 million years ago.

 Known for it's gray and grizzled fur, it will typically have a rust red coloring around it's neck, legs, ears and tail, towards the underbelly and below the gray. It has a black-tipped tail similar to the Fennec and other African foxes, and is easily distinguished from the Red fox this way.The gray fox's face tends to be less pointy than the Red fox, and has rounder ears. Instead of slit-like pupils, like a cat and other foxes, the Gray Fox has more round pupils.

They typically weigh from 8 to 15 pounds, with the largest reported Gray being 20. The females are only slightly smaller than the males, unlike many other fox species.  

Behavior/Reproduction: The Gray Fox also likes to climb trees, similar to the Raccoon Dog, and will often be seen at night climbing trees, or during the evenings since this mammal is crepuscular.

Gray Foxes are monogamous, meaning they mate for life with one partner. Their mating season varies depending on location from early late February to July. The gestation period is 53 days and they can have up to 7 kits in one litter, the average being 2-3. 


Diet: In the wild, they would be omnivores, so their diet in captivity must reflect this. Blue Buffalo Wilderness diet is amazing with fruits and vegetables mixed in about every other day. Also, foxes need more of the vitamin Taurine than canines do, so I would recommend giving them raw meat or cooked meats - chicken is the healthiest - every so often as treats or supplements. Some people feed their foxes cat kibble, which I do not usually recommend, since this can lead to liver problems later in life. Blue Buffalo Wilderness and Taste of the Wild are really high quality brands. And remember, if the ingredients don't have an actual meat (such as 'deboned chicken' like in the Blue Buffalo) listed as the first ingredient, don't buy it. All these commercial dog or cat foods that have corn in them are not as good. Cats, dogs, and foxes would not be eating corn in the wild. Also, foods in pet specialty stores are generally going to be healthier than commercially sold foods. It is a little more expensive, but all exotic animals are. 

Captivity: In captivity the Gray Fox needs a cat tree, or something acceptable to climb if kept indoors, otherwise, they will be seen climbing your cabinets, refrigerator, you name it! They also have a scent marking behavior much like a cat, where they will rub different parts of their body on something they want to claim. However, there is no foul odor as with a Red's urine, and they seem to have no offensive body odor, much like the Fennec. Special care should be taken, since these animals like to climb, when on walks. I would only ever recommend walking with a harness, since all foxes are so small and fragile that them pulling too hard on their collar could damage their trachea. And if they did get off leash, they could not only run but climb. Harnesses should never be left on unless supervised to prevent damage to themselves. 

Range: Gray Foxes are found very widespread throughout North America. They cover almost all of the United States, the top of Mexico, and some of the southern provinces of Canada. Outside their north South America range, there is the South American Gray Fox, which is in fact not a subspecies at all but a separate species entirely. Gray Foxes prefer dense trees and vegetation as they climb trees often and make dens for their kits in the brush on the ground. However, they can be found within the confines of the desert and sparse vegetation, such as prairies like their Swift and Kit fox relatives.

Color Morphs: There are only two known color morphs for the gray fox, an all white color, and a leucistic, which simply gives it a lighter, cream colored coat where the darker blacks and grays of the coat would normally be. Both color variations are extremely rare, almost never found in the wild. There are no known breeders of the leucistic color morph.
