Winged cat

Winged cats is a term for sightings or descriptions of cats with wing-like appendages.

Description

There are three different causes of wing-like appendages. The most common is longhaired cats having matted fur. Felted mats of fur can form along the body and flanks if a longhaired cat is not properly groomed. Less commonly, mats can occur in shorthaired cats if molted fur adheres to growing fur over several seasons. When the cat runs, the mats flap up and down giving the impression of wings. These can be very uncomfortable for the cat and can harbour dirt, feces and parasites. Extensive mats must be shaved or clipped by a veterinarian. This explanation is ultimately untenable as the sole solution to the winged cat phenomenon, for several reasons. Many notable examples of winged cats feature shorthaired specimens. The occurrence of mats in longhaired cats is easily recognisable by experienced cat owners and breeders, but not recognisable to novices. Matted fur is not considered notable and rarely reported, except by those unfamiliar with the condition. Although mats can occur all over a longhaired cat's body, to novice eyes, they are most noticeable on the flanks when the cat is in motion.

The second explanation of reports of winged cats is a skin condition called feline cutaneous asthenia, or FCA, which is related to Ehlers-Danlos Syndrome (elastic skin) in humans. In winged cats that are due to FCA, the wings only occur on the shoulders, haunches, or back. Winged cats that are due to FCA can often actively move their wings, suggesting the presence of neuromuscular tissue within the wings, which is not present within clumps of matted fur alone.

The third explanation is a form of conjoining or extra limbs. These non-functional or poorly functional extra limbs would be fur-covered and might resemble wings, as in one winged cat case recently documented by Dr Karl Shuker, in which the wings were shown to be supernumerary limbs.

There are more than 138 reported sightings of animals claimed to be winged cats, though some of these are clearly nothing more than individuals with clumps of matted fur. There are over 30 documented cases (with physical evidence) and at least 20 photographs and one video. There is at least one stuffed winged cat, but this may be a nineteenth-century fake or "grift".

Historical winged cats

During the early 1990s, British zoologist and cryptozoologist Dr Karl Shuker, who has a longstanding interest in the winged cat phenomenon, became the first person to make the link between winged cat reports in the popular media and reports of feline cutaneous asthenia in the veterinary literature. Publishing his findings in a series of articles appearing in several popular magazines including Fortean Times, Fate, Cat World, and All About Cats, he has compiled a comprehensive survey of winged cat cases, many previously undocumented, which he periodically updates and which may be referenced for more information. His articles include coverage of the vast majority of the following examples. In 2008, Dr Shuker published the most comprehensive documentation of winged cats currently in existence, as an extensive chapter within his book Dr Shuker's Casebook (CFZ Press: Bideford), including several previously unpublished cases and photographs. There are some additional, less significant examples in magazines, newspapers and personal accounts by owners, including cases of both FCA and matted longhaired cats.

Feline cutaneous asthenia

Cutaneous asthenia ("weak skin") is a skin deformity characterised by abnormal elasticity and stretching of the skin. Pendulous wing-like folds of skin form on the cat's back, shoulders and haunches. Even stroking the cat can cause the skin to stretch and tear. The flaps may include muscle fibers allowing some movement, but the cat cannot flap them in a bird-like manner, though the wings may bounce up and down when the cat moves.

Cutaneous asthenia is caused by a collagen defect. Collagen is the protein that binds the cells of the dermis together. It is also called dermatoproxy, hereditary skin fragility or cutis elastica ("elastic skin") and is found in humans (Ehlers-Danlos Syndrome, or EDS), dogs, mink, horses, cattle and sheep. In cattle and sheep, it is called dermatosparaxis ("torn skin"). In horses, a similar condition is called collagen dysplasia. The skin is also abnormally fragile. The skin flaps peel or slough off very easily, often without causing bleeding. This explains why cats with the condition suddenly "molt" their wings.

A recessive autosomal (non-sex linked) form of feline cutaneous asthenia has been identified in Siamese cats and related breeds. In the homozygous state, it is apparently lethal.

Veterinary reports

An undated veterinary report describes a six-month-old non-pedigree tomcat which presented with two skin wounds on the right side of its body. The skin on the affected areas and on its back was hyperextensible, smooth and easily torn by just a small amount of pressure. Microscopic examination revealed abnormally low levels of connective tissue.

Cats with the condition cannot be grasped by the scruff, as this may tear away. The syndrome is also linked to slipping joints. Dietary supplements may be needed to promote skin healing and regrowth. Antibiotics may be needed to combat infection when skin has split or torn.
