Bolo - 31 Aug 2004 03:16 GMT I was just wondering what everybodies favorite purebred is.I have a male ragdoll (Max) and a female maine coon (Xena) and I think they are the best cats in the world but I would like to hear about other purebreds.

No doubt. Why pay hundreds or thousands for an inbred when they are killing hybrids by the thousands? Hybrid vigor and all that...

> cats in the world but I would like to hear about other purebreds. The breed with the most (18) documented genetic defects is the Siamese followed by the Persian and Burmese.
Brachycephalic Airway Syndrome - Persians and Himalayans have the most worst conformation. Now that's a particularly nasty defect that didn't even exist in nature until some moron decided cats should have flat faces, round heads, and short thick necks.. Maybe he was trying to create a cat in his own image.
The respiratory muscles of these cats have to generate more force to produce airflow through the narrowed air passages. This can result in barotrauma to the mucosal lining of the airways. In severe cases the respiratory muscles become fatigued which can result in ventilatory failure. Brachycephalic dogs especially the English bulldog - which usually requires surgery (Pekingese, shih tzus, Lhasa apsos, shar peis) can have the same problem.
Manx and Manx mixes are prone to rectal prolapse and sacrocaudal dygenesis (malformation of the sacrocaudal vertebre) - probably as a result from tailless breeding. Now that was a stroke of pure stupidity; breeding cats without a tail... Cats use their tails for balance.
The list goes on but I'm too nauseated to continue.

Obviously this condition can occur in any cat, whether or not purebred. It is more commonly associated with larger, heavier cats and so one would expect to see an association with the larger breeds, but also with larger cats of mixed breed as well. At least with Maine Coons, there is a registry that screens for this condition so that breeders can try to reduce prevalence by not breeding affected cats. With a mixed breed cat you are not likely to know whether the cat has inherited a risk factor.

[quoted text clipped - 12 lines] > Seems to me that when you get right down to it, > "purebred" just means "inbred." That's probably why purebreds are often more susceptible to disease.
Dr. Neils Pedersen, a world renowned expert on feline viral diseases said in his book on feline infectious diseases:
"Fragile strains of purebred cats are often more susceptible to FIP, probably because of decreased overall disease resistance."
The Bristol study confirmed that fact in which the prevalence of FIP in purebreds was nearly twice that of DSH. Prevelance was highest in the Burmese followed by the Siamese.
Some people put too much value on that piece of paper. Unless you actually witness conception and birth, there's no guarantee the kitten actually came from the parents named in the registration.
Don't get me wrong, I'm not blaming the cats - I love all cats - I just have a problem with breeders in general.

Like it or not, basically any living thing encountered by humans is bred to suit our whims and desires. All livestock, all pets, plants, the whole deal. Even the humble moggy has to adapt to the pressures of human society - one reason why tabby cats are prevalent, indeed.
As you may guess, I have no real problem with this, except when animals are bred that are fundamentally unfit for survival. For example, hairless cats are unfit in a Darwinian sense - even the most robust, the most perfect Sphynx, is not fit for purpose. It could not survive in the Great Outdoors. On the other hand, cats such as Siamese, Abys, Russian Blues, whatever, are not fundamentally flawed, although they may often be so in reality, due to poor breeding practices.
> Seems to me that when you get right down to it, > "purebred" just means "inbred." It often is, although it does not have to be. In principle, a cat created via controlled breeding could well be superior to the moggy. Generally doesn't happen that way though - conformity seems to be favoured over robustness. Hence the various problems many purebreds suffer from.

Cats would not have become domesticated without selective breeding, because the cuter, friendlier cats were the ones most likely to get a handout from the human beings who met with them, and therefore more likely to survive and pass on their attractive, friendly genes.
>As you may guess, I have no real problem with this, except when >animals are bred that are fundamentally unfit for survival. For [quoted text clipped - 4 lines] >although they may often be so in reality, due to poor breeding >practices. I agree with you. Some of the historic breeds, that have been in existence for hundreds of years, are (or were until recently) hardy, healthy breeds.
>> Seems to me that when you get right down to it, >> "purebred" just means "inbred." [quoted text clipped - 4 lines] >favoured over robustness.

Some are generally hardier and more long-lived than the average mixed breed cat, although that may be more due to the overall genetic background of that breed than to the knowledge of the breeder. While certainly the best breeders attempt to breed out genetic defects and strengthen a breed, I think too few breeders know what they are doing well enough to be able to do more good than harm.

All other breeds are simply mutations of the original.

There is plenty of inbreeding going on among mixed breed cats.

Not exactly. The gene pool in naturally bred cats is so vast that they still retain their hybrid vigor. Genetic defects are also much less common in naturally bred cats.

I think Dr. Pedersen was speaking generally...

Dr. Neils [quoted text clipped - 5 lines] > >I think Dr. Pedersen was speaking generally... Then I have to agree with Steve G., that if he means some breeds may have "fragile strains" that is probably true, but if he means purebred cats in general, that cannot be true. Some breeds are quite hardy, and some "strains" within various breeds are certainly hardy and long-lived.
In any case the reason some cats develop FIP while most do not is not well understood. Dr. Pederson is merely offereing his own theory.

Genetic susceptibility factors might also play a large roll. The Bristol study showed a higher prevelance in purebred than natural-bred cats with the Burmese taking first place followed by the Siamese. Some lines of Persians and Birmans also have enhanced susceptibility to FIP.

Foley JE, Pedersen NC: The inheritance of susceptibility to feline infectious peritonitis in purebred catteries. Feline Pract 24:14-22, 1996.
I'd say his theories are highly credible since he's one of, if not *the* foremost FIP researchers in the world! A lot of his work in FIP involves purebred cats because of their increased susceptibility.

> I'd say it a little more than just a theory... > [quoted text clipped - 5 lines] > foremost FIP researchers in the world! A lot of his work in FIP involves > purebred cats because of their increased susceptibility. However, things are not quite as you suggest...
From http://www.winnfelinehealth.org/health/FIP.html
"A genetic predisposition to the development of FIP was identified by Drs. Foley and Pedersen in 1996. They examined pedigree and health data from 10 generations of cats in several purebred catteries and found that the heritability of susceptibility to FIP could be very high (about 50%). It is likely a polygenetic trait rather than a simple dominant or recessive mode of inheritance. Inbreeding, by itself, is not a risk factor. Selecting for overall disease resistance is a helpful tool for breeders"
Note - Inbreeding itself is not a risk factor. Poor breeding practices are - i.e., repeatedly breeding from lines that suffer from the genetic defect.
Or, using an analogy, from time to time, bad science is carried out. However, this does not mean that all science is bad and that science should be stopped forthwith.
It is also possible to breed for enhanced health. For example, IIRC, there is a lot of research into breeding chickens for improved immune systems - presumably so that they can be crammed into teeny tiny cages with less chance of succumbing to illness.
Steve.
Yngver - 09 Sep 2004 18:38 GMT >(...) >> [quoted text clipped - 33 lines] >systems - presumably so that they can be crammed into teeny tiny cages >with less chance of succumbing to illness. Furthermore, I point out that no doubt the reason Dr. Pederson studied the heritability of susceptibility to FIP in purebred catteries is that it would be quite difficult, if not impossible, to examine pedigree and health data from 10 generations of random bred, non-pedigreed cats, wouldn't it? This is the case with many studies conducted on genetic health links; the health and lineage data exists for purebred cats so that's the group of cats that are studied.

No. Research colonies are often kept for generations specifically to rule out/in genetic susceptibility.

Steve G - 10 Sep 2004 22:16 GMT (...)
> Things are exactly as I suggest. The Bristol study supports me. Available research does not support the statement that breeding of purebred cats invariably leads to an increase in genetic defects. Indeed, in the abstract from Foley & Pederson, the authors state:
'Cat breeders might achieve success in reducing FIP risk by selecting cats from less susceptible lineages for their breeding programs.'
Note that they do not say 'cat breeders must stop controlled breeding in order to reduce FIP risk'.

> 'Cat breeders might achieve success in reducing FIP risk by selecting > cats from less susceptible lineages for their breeding programs.' > > Note that they do not say 'cat breeders must stop controlled breeding > in order to reduce FIP risk'. Yeah, I know. They said "cat breeders **might** achieve success in reducing FIP risk by selecting cats from less susceptible lineages". *Might* doesn't sound very reassuring, and "susceptible lineages" seems to mean, well, entire lineages are susceptible - ah yes, "line breeding". Imagine that - entire lineages being susceptible to FIP! Now that's a scary thought! I wonder what breeders do with those lineages... You know how terrified breeders are of being known to have FIP in their cat factories.
From your Winn reference: "The likely defect in immunity to FIP is in cell-mediated immunity. Therefore cats that are susceptible to FIP are also likely susceptible to some other infections as well, especially fungal and viral infections. " Wow! Imagine that, entire lineages have defects in CMI that makes them susceptible to all kinds of diseases! Entire lineages...
You don't have much actual experience working with cats and vets, other than your own, do you? It doesn't seem like you do Almost every vet I've worked with or even knew in the last 40 years, including my vet whose a double-boarded, retired veterinary professor, were of the opinion that generally purebred cats are more susceptible to disease. These are vets who work with just about all the breeds of cats on a day to day basis for decades. My experience working with cats for >40 years on a day-to-basis tends to makes me agree with them. You can bob and weave in your philosophical debates all you want, but nothing but nothing beats real life practical field experience and empirical evidence.

Well, the former is (obvously) true to some extent but I'm certainly not universally pro-breeder, and there are several breeds I do not believe should exist. I also think that breeding should be much more tightly controlled than it is, and that Joe Public should not be able to set up a breeding concern basically on a whim. FWIW (piece of chewing gum and a bit o'string, probably).

I do not disagree that some lines (or even breeds) are more susceptible to disease, what I'm saying is: i) not all lines (or breeds) are susceptible, and ii) susceptibility is not an effect of breeding per se (or even inbreeding per se); it is an effect of poor breeding practices (re. the Winn URL).

Dr. Neils > Pedersen And someone who said that is NOT disagreeing with my above statement, viz. 'breeding does not necessarily (does not have to) lead to a loss of vigor'. Poor breeding practices can (and do) lead to problems, but good breeding practices will not. Your (referenceless) cite has bugger all to say about this.
Incidentally (as Yngver points out elsewhere), the statement by Pedersen is ambiguous in the above context: Does he suggest that *all* purebreds are fragile, or that breeds exist that are fragile? The latter is a reasonable statement, the former is likely not.

Responsible breeders generally would not allow matings between such closely related cats, but if you say this small pool of neighborhood cats is retaining their "hybrid vigor," okay. They don't appear to be very healthy cats, but possibly that is more because they are not fed well. It's true the patriarch of the family has lasted about five years now. I don't think most of them have lasted long enough to find out what sort of genetic health problems they may have inherited.

Nature occasionally makes mistakes.

Some mutations are not functionally significant. The vast majority are bad. A few are good.
I would guess that, as organisms approach an ideal configuration for their environment, the higher the percentage of mutations that are bad.
Still, it would be pretty cool to have a tail.

[quoted text clipped - 16 lines] > >Still, it would be pretty cool to have a tail. Yes, nature generally takes care of its mistakes by not letting them survive. If one considers the Manx cat a mistake of nature, it is one that has managed to survive and perpetuate itself for hundreds of years before breeders put a hand in it. The Manx is what I would consider a natural breed; in other words, the breed arose naturally rather than having been created by breeders attempting to create a tailless cat.
Taillessness is not necessarily associated with genetic defects. The Japanese Bobtail, an even more ancient breed of cat, and another natural breed, is generally regarded as a healthy breed of cat with no specific genetic problems.

That's not entirely accurate.
"A spontaneous mutation occurred at some point several hundred years ago, which created kittens born without the vertebrae that form the tail of normal cats. With the passage of centuries and due to the isolation of the cats from outside breeding, the taillessness eventually became a common characteristic among the Isle of Man cats"
"Other breeds of cats occasionally produce a kitten with a missing tail. The Manx, however, is the only cat that is bred to be tailless." http://www.fanciers.com/breed-faqs/manx-faq.html#history

For example, each human has, on average, 7 true genetic mutations. There is a ton of DNA in each genome that isn't in frame with any coding region. And even if the mutation occurs within a coding region, most point mutations are tolerated.

I have a beautiful Chartreaux. Her name is Spot (Actually it's Nous nours Bleu Rapture but, I mean really). She's a big girl, about 10 pounds, slate grey with gold eyes. Not a lap cat but likes to be near me, follows me around the house. Ever night around 11p, she comes into my bedroom, pats me on the face for treats, then curls up on her corner of the bed.
Although when seriously stressed (having blood drawn) she screams, she doesn't meow. She opens her mouth and sometimes a little squeak comes out.
She travels with me regularly, by car. I take her to my boyfriend's house when I go there for the weekends (180 miles). She doesn't seem to mind going to a different house. I took her with me when I drove to my parents' (1000 miles).
Like her French farm cat forebearers, she's a great mouser. (We live in an old house. Mice get in. Of course, having a live mouse dropped on your back at 4am is not so much fun.) She gets along beautifully with the older DSH male who also lives in the house.

She's a big girl, about 10 [quoted text clipped - 7 lines] > the rounded shape of her head and her pretty little muzzle. Now we need some > stories to go with the pics! I hadn't realized how rare this breed of cat was until after I had gotten her. (For all of those of you out there who would prefer that people adopt cats from shelters: Around the time I got Spot, I also rescued an abandoned kitten, paid huge vet bills to have her brought back to full health, medicated her several times a day and then found a loving home for her. Her name is Mimi.)
Spot has the ability to vanish into other dimensions, probably the one with the socks. When we have parties, she is shut in my bedroom as she doesn't like small children and will hide somewhere I can't find her and I get agitated. One night, I came into my room at the end of the night and... no cat. I looked under everything, in the closets, under the bed, behind the radiator. No cat. I thought perhaps an inquisitve toddler had let her out. I searched the house. No cat. I decided to calm down and wait. Ten minutes later, she was sitting next to the bed. The door to the bedroom was still shut...
We have to be careful because, as she doesn't meow, she will just sit where she gets stuck until we find her. Stuck would include a door that is mostly closed but not latched. I've never before had a cat who couldn't figure out how to open a door!

Mostly just opens her mouth a little as if she were meowing but no sound. The only other cat I ever had who did that was one who had been abandoned before she was weaned. She never learned to meow properly or do a lot of other normal cat things. But with Chartreaux, it's normal.

He had some sounds earlier on, but he had surgery that ruined any sound that he tried to make and he did what you described, didn't try to meow. He grunted, and when he was upset by one of the other cats he would try to hiss but even that never came out. All of the years he was with me, he never really vocalized. I wonder if he had some genes in him from a breed that didn't make sounds. He sure did purr, though. You could hear him from across the room. :)

I have seen Chartreux at cat shows and they have a that distinctive silver shimmer to the plush fur. These pictures do a good job of illustrating the unique qualities of the Chartreux. Sometimes they are confused with the British Shorthair (blue) but the coat quality and shape of the nose are not the same.

I sent the pictures to the breeder who said she was sorry she hadn't kept her for breeding. When I got Spot's registration papers, TICA had mad a mistake and instead of it saying "Not for Breeding" under her name, it says it under mine!

But in the pictures I've seen they do seem to >have a different face shape. Here's what it says on the CFA site: "Chartreux and British Blues Some cat books claim that the Chartreux is the same cat as the British Blue, or that it "once was a separate breed, but has now become identical to the British Blue." This is not true. Not only do the two breeds have different physical and temperamental characteristics, but pedigree research and blood typing confirms that the breeds have distinct ancestry. These books are referring to the confusing use of the name "Chartreux" by certain European cat clubs to refer to the British Blue. In 1970, FIFe (the European federation of cat fanciers) decided to assimilate the Chartreux with the British Blue under the name "Chartreux" but with the breed standard of the British Blue. This decision came about because many of the member countries were not interested in the Chartreux as a breed, but preferred the name "Chartreux" with its long history to the less interesting name "blue British Shorthair." They sought to save the name and apply it to another breed. Chartreux breeders protested, and in 1977, FIFe overturned its earlier decision and returned to separate registries and standards for the two breeds. However, since the 1970s, a few "independent" (non-FIFe) European cat clubs have continued to use the name "Chartreux" for the blue British Shorthair, or for the blue European Shorthair, or for hybrids between these breeds and the Chartreux. This practice is more common in those countries like Germany where there are fewer genuine Chartreux available." ******* I know a British shorthair breeder and once you get to know them and the Chartreux, there are a number of distinctive differences between the two breeds. There are similarities too, but people familiar with the breeds would not mistake one for the other. Chartreux have a distinctive look in the face and nose, that's hard to explain.

I think that Bengals are perhaps my second favorite breed, my fave being Abys. On the other hand, I've seen nowt but pictures of many breeds, and I do like the appearance of Cornish Rexes, Ocicats, Savannahs and other oddities I'll never meet.
On the other (moggy) hand, I like any (big) tabby (one of my cats is a big Maine coonalike) and cats with grey / blue coloration.
Actively dislike any of the flat-faced abominations, also Sphynxes and the like.
FWIW, Steve.

Phil P. - 01 Sep 2004 08:11 GMT I would like to hear about other purebreds.
This cat was surrendered to a county shelter as a bitter after she was declawed. She didn't even have a scratching problem before she was declawed. Imagine a cat being declawed, then being surrendered because she became a biter after being declawed... How's that for a horror story?
We rehomed her twice - both times she was returned because of biting, then I adopted her. It took about a year, now she's out smooches all my other cats! She still gives little love nips when she gets excited but never breaks the skin - so does my girlfriend so I'm used to it.
She looks like a Turkish Angora - all white with blue eyes (no, she's not deaf) - a real knockout!

I love Persians. They are so laid back andloving. But, as many people have said on this newsgroup, they have been inbred and solive do not live very long lives. My latest Persian does not have the flat face and I hope that the breeders are getting away from that abomination. I also have a 21 year old "alley cat" who has a cast iron immune system. She is thriving!

Everyone in our family thought she was the most beautiful cat we had ever laid eyes on. Back then the Silvers for some reason had doll faces, not the flatter faces that most of the other colors had. Nowadays when I see them at cat shows they seem to have the same flat faces the other Persians have, although the extreme flat faces seem to have gone out of fashion.
