This is one of the Rex cat breeds, which are curly haired cats (see cat coats curly). The other well known, in fact better known, curly haired cat breeds are the Cornish Rex, Devon Rex and the LaPerm. Curly haired cats arrived out of a genetic mutation and were discovered and then bred to create a cat breed. At the time of discovery these cats were household pets or semi-feral cats. Until the formation of the cat fancy in the late 1800s cats were not formally differentiated into cat breeds.

It is interesting to note that the discoveries all occurred at a similar time indicating that the discovery was dependent on an interest in the idea of turning a genetic mutation into a cat breed. It is almost certain that there were many occasions prior to the discoveries when other curled haired cats were in existence but the cat keeper took no notice or the cat was feral and had no human keeper. Discovery is dependent on interest.

These are the dates on the origins of the Rex cats:

LaPerm - USA - 1982
Devon Rex - UK - 1960
Cornish Rex - UK - 1950 - see more on origins
German Rex - Germany - 1947 - more formally in 1951 - and possibly in 1930-1 (see below).

We can see therefore that the interest in cat breeds that I refer to above was evident during the 1950s onwards. The most prolific time for the creation of cat breeds was the period 1950-60 and 1980 - see cat history time line. The German Rex cat breed started during this active period in the cat fancy. Perhaps it was almost fashionable (this is not a criticism in any way) to develop a new continental curly coated cat breed at that time.

Origin - History

The date of origin is probably best described as being in 1951 when a certain hospital doctor named Dr Rose Scheuer-Karpin discovered a curly haired cat in the hospital grounds. The hospital was and probably still is in the Pankow borough of Berlin - see green area in map below (see base of post for copyright rights etc. on photos):

The black curly haired cat seen by Dr. Scheuer-Karpin was known to staff at the clinic from about 1947. Some 20 years earlier in Königsberg (Eastern Germany I believe) another curly haired cat was "discovered". He was named Munck and his owner (keeper) treated Munk as a pet and thought nothing of it. In the 1930s the cat fancy was at a fairly early stage and very few if any new breeds created. The Persian appearance was beginning to be changed in America by my reckoning at about this time (some people will disagree with this) - see Persian cats.

Anyway I think it a fair assessment to say that the German Rex cat started life as a cat breed in about 1951 with the doctor. Here she is:

This above image comes from Wikipedia® User:Tamstudi (see license below), who is a member of the German Rex Cat Club. On the left is apparently the earlier discovered cat Munk and on the right the German Rex cat to be, named Lämmchen by the doctor. This is obviously a montage and the fact that a picture of Munk is featured indicates that a connection was made between these cats and that Munk was known despite being treated as no more than a pet. The connection may be more profound in that Munk could have been the great grandfather of Lämmchen.

I think this a little unlikely considering the distance between the two and the fact that incidences of the recessive gene showing in cats although rare was not and is not that exceptional. Although as the Wikipedia author says a the time after WW2 there was a lot of people displacement and Munk could have been brought with the person keeping the cat when travelling west.
founding Cornish Rex cat
The first time I saw these German Rex cats, I thought they looked pretty solid, stocky cats and not at all like the American Cornish Rex, which is noticeable slender or the pixie faced and rather delicate Devon Rex bred in the USA. Both Munk and Lämmchen are both originals as is Kallibunker the founding Cornish Rex (see what I believe to be his photograph on the right here).

Both the German Rexes are slightly bulkier cats it seems, while the founding Cornish Rex is lean and athletic. I suppose this is simply chance in that the gene responsible for the curly hair happened to find itself in a bulkier or lighter cat; in other words the conformation (overall body shape) is not linked to the curly hair.

Moving on - what happened after the doctor found Lämmchen? Lämmchen was a female. The doctor I am going to presume was a cat breeder of sorts (perhaps well established I don't know) as she progressed the breed (somewhat but a little haphazardly - see below) and considered that Lämmchen's coat was a result of a genetic mutation, which was correct. I don't know if Dr. Scheuer-Karpin considered whether the mutation was the same as that in the Cornish Rex. Lämmchen became the founding female cat of all German Rex cats.

There would seem to have been "uncontrolled" breeding by Lämmchen after the doctor found her, which does not seem very much like a cat breeder. Of course, Lämmchen would or could have produced offspring before 1951 and so there are probably curly haired cats living in Berlin to this day, undiscovered or unnoticed whose great grandmother is Lämmchen.

Anyway the breed got off the ground although at one stage only 3 descendants of Lämmchen existed. The early progression of the German Rex cat breed depended on breeders in Grund (Barensfeld family).

It would seem that over the intervening years the development of the German Rex breed faltered on occasions but survived at a somewhat low level. The German Rex cat is now recognized by the World Cat Federation (WCF) and Federation International Feline (FIFe) and has been exported to the USA.

Breed Standard - Appearance

The breed standard is taken from FIFe and this is a very brief overview of the modern day requirements for this breed of cat.

This is clearly still a medium build cat of moderate type, which indicates that the original conformation has been preserved (c.f. the American Cornish Rex). The head should be rounded and the whiskers short and curly. The body should be medium in length.

The ears should be medium large. There would seem to be no restriction on coat color and pattern. This cat is all about the curly hair.

The guard and awn hairs of a cat are the top coat. The down hairs are the undercoat. The down hairs are the thinnest and feel softer. The Rex coat is typically soft and it was thought that this was because the top coat has been removed by this genetic mutation. This is incorrect it seems. The hair fibers are in fact reduced in thickness and length. The guard and awn hairs are affected the most. This gives the soft texture. The German Rex cat has more awn hairs than in the other Rex cats. The difference in thickness between the awn hairs and the down hairs is more marked in the German Rex cat. There seems to be no guard hairs, however. The whiskers are bent.

The German Rex coat is typical of the Rex cats, smooth, soft and wavy. As I may have mentioned above the gene that produces the curly coat is autosomal recessive.

Cat Ear Mites

Brown gunge. Yes, I know this is a ferret! It does show the build up of dark brown to black ear wax caused by the presence of the cat ear mites in the outer ear canal. This parasite is not restricted to the domestic cat, which makes this photo valid and a useful illustration (I was unable to find a suitable photo of a cat with the condition). Photo Stacy Lynn Baum under a creative commons license. Ear mites (minute crab like creatures) are one of the causes of inflammation of the outer ear canal (scientific term for this inflammation is Otitis externa ). The outer ear canal is the tube that runs from outside to the ear drum (the pathway for the reception of sound), which can be seen when looking at the ear. Otitis externa affects humans and often swimmers as it is called "swimmer's ear" in humans. This YouTube video show ear mites under a microscope. They are not actually in the ear in this video. There are many possible causes of Otitis externa in c

Feline Mange

I'll write about three types of feline mange (a) feline scabies or head mange (b) demodectic mange and (c) sarcoptic mange. The source material is from Cat Owner's Home Veterinary Handbook - the best on the market . Generalised feline mange? Puerto Rico - Photo by Gotham City Lost And Found Feline Scabies - head mange Head mange or feline scabies, is a fairly rare condition in cats, which is caused by the Notoedres mite (head mite) that only reproduces on cats. The female mites burrow a few millimeters (that is a lot) into the skin around the head, and neck to lay eggs, which hatch and lay their own eggs. Their presence and activities causes intense itching that in turn causes the cat to scratch. The scratching will obviously be noticed and it will cause the skin to become red, scratched and worse infected. Symptoms: hair loss and scabs, thick wrinkled skin and grey/yellow crusts form plus the symptoms of scratching. Feline mange (head mange) is contagious and tr

Cat Anatomy

Cat Anatomy - Photo by Curious Expeditions . The picture above was taken at Wax Anatomical Models at La Specola in Florence, Italy. The photograph is published under a creative commons license kindly granted by the photographer. I am sorry if it is a bit gruesome. It is pretty well all I could find as an illustration that was licensed for publication. Cat Anatomy is a very wide ranging subject. The anatomy of a cat is very similar to human anatomy. If you were writing a biology book for students of biology you would go through every part of the a cat's anatomy in some detail. It would be similar to writing a book about the human anatomy. It would be a thick book and pretty boring for your average internet surfer. So, how do you limit such a big subject and make this post meaningful? The answer I think lies in doing two things: Having a quick general look at cat anatomy - an overview and; Focusing on the areas of cat anatomy that are particular to the cat and of parti
