The following items have been checked:
Microchipping is mandatory for all white cats of all breeds.

1. Mandatory tests Those are tests which can be done by every veterinarian when you visit your vet for the periodical vaccinations.

Make a cross where applicable:



Remarks of the vet Here the veterinary surgeon enters his comments if necessary.
Monorchism, cryptorchism

That means that in males only one testicle or no testicle can be felt. It is a genetic defect, which is inherited. This defect is inherited by both parents, also the female may carry this defect and thus should not be used in your breeding program.

It is not permitted to exhibit blind cats or to use them for breeding.

This is likely to be seen in cats with points, but can appear in all breeds, not only in Siamese.
Patella luxation

Mostly it is found in the hind legs, the patella is loose and might jump out of the tiny channel in which it normally is anchored. Do not make any check by yourself, you might put severe damages to the cat. Cats which have this problem, can get severe problems with their movement when aging, thus an operation might be inevitable.
Fixed deviation of the xiphisternum

The xiphisternum is located at the end of the sternum, it is a short bone which might bend outwards so that it is visible from the outside. sometimes this deviation is flexible, thus it might disappear when the cat matures. It is the job of the veterinary surgeon to check this. It is a defect, which can be seen more frequently in Siamese, also in Persians and Exotics, but it can appear in all breeds. When the deviation is reversed inwards, mostly only a surgery can solve that problem.

Umbilical hernia

The consequence of an umbilical hernia can be that the intestines protrude into the abdomen. This is a rather severe problem and shall be solved by a surgery. This defect can be seen in British shorthair, in some Abyssinian lines, but no breed is excluded from this defect. Cats having this defect must be excluded from breeding, because also this defect can be inherited like several other defects.
Complete vaccinations:

Panleukopenie, Rhinotracheitis, FelV
(vaccinations must not be older than 1 year !)

In a kitten a complete vaccination includes both the 1st shot and the 2nd shot. Each vaccination in kitten when vaccinated for the very first time must be given twice within a period of 4 weeks between both shots. One shot only does not establish any protection.
The next years the vaccination must be repeated only once.

(fleas, mites)

Fleas are mostly around the neck and at the base of the tail. One can see their traces, the so called flea bites. Fleas can transmit worms.
Mites, ear mites are mostly in conjunction together with dirty ears. Bur be careful, the diagnosis has to be done by the veterinary surgeon. Because of dirty ears one cannot draw any conclusion that mites are present.
  • Prognatism
  • torsed canines



The bite plays an important role in the cat's life, as the cat is a hunting animal by its nature. A cat does not chew its pray or food, it swallows it.
Prognatism means that either the upper jaws protrude over the lower jaw or vice versa, this problem increases when the cat matures. Such cats frequently use their paws to catch their food, because they can't catch the food properly with their teeth. This is even more likely when the canines are not set parallel, or when the jaws are twisted. One can notice these problems in so called extreme breeds, those are breeds with extremely short noses or breeds with very long heads. Therefore a responsible breeder will take every measurement in such breeds that the bite is absolutely level.
Eyes/Respiratory tract:
  • Entropium
  • nostrils too small (more high than broad)



In extreme breeds, where the skull is extremely shortened or is extremely long, one can notice several problems concerning the eyes or the respiratory parts, especially concerning the nose:
tearing eyes, because the nasolacrimal tract is shortened or cracked,
very deep set eyes, where one can see the nictating membrane,
bulging eyes,
entropium, where the lower eye-lid is turned inwards, thus the fine eye lashes permanently irritate the eyes.
Too narrow nostrils, for example a snubbed nose which might cause problems for the cat.
A responsible breeder will emphasize on harmony in the proportions and will take every measurement that those problems do not appear in his breeding stock.
Whiskers present

Whiskers are a primary organ and thus play an inevitable role in the cat's orientation. When the whiskers are not present, the mobility and movement of the cat can be severely disturbed.




OB means without medical evidence.  By listening with stethoscope a veterinary surgeon is able to detect if the respiration of the cat functions normally.




The veterinary surgeon is able to detect if there might be any problem with the heart when listening to the sound and rhythm of the heart, for example if it might be necessary to make a sonogram. In some Siamese, Persian and Exotic lines heart problems have been detected in the past, when kitten die with a very early age.
General external clinical evaluation



The veterinary surgeon will check size, weight and the general development status of the cat.


2. Mandatory tests for white cats Those are mandatory tests which must be done.

An audiometric test for all white cats of all breeds has to be included as annexe.

Clapping into the hands is not an appropriate test method, because cats react to the slightest air movements. White cats, mainly white cats with blue eyes (both eyes blue, or odd-eyed) may inherit deafness. Deaf cats are not unhappy themselves, they adapt to their surrounding very fast and very well, but they cannot take care of their kitten, because the normal communication is handicapped because of the deafness.
Therefore it is forbidden in our club to cross white cats with white cats.

All Korat cats used for breeding must have a DNA-test for GM (Gangliosidosis)*.
All Norwegian forestcats used for breeding must have a DNA-test for GSD IV (Glycogenosis type IV)*.
All Burmese cats used for breeding must have a DNA test for GM II (Gangliosidosis type II)*.
*or negative DNA-test results of the respective disease of all parents of the breeding partners must be presented.

GM is a very severe damage of the brain, it leads to severe drop outs in the movement and last but not least the kittens die very early.
GSD IV describes the accumulation of abnormal glycogen in myocytes, hepatocytes or neurons; that cause lethal tissue demages. Affected kittens die for hypoglycemia very early after birth. Surviving cats die before 5 month of age for progressive muscular degeneration.

3. Recommended tests Those are tests which are strongly recommended for the following breeds.

Make a cross where applicable:



Remarks of the vet
Hip dysplasia
Persian, Exotic, Maine Coon
Breeds with heavy bones may inherit deformations in the hip bones, which can lead to lameness and where a surgery is inevitable. This test is done by x-ray.
Polycystic Kidney Disease (PKD)
Persian, Exotic, British Shorthair
PKD can be detected with ultrasonography, the ulrtrasonograph must support a sufficient Hz-frequency, and the veterinary surgeon must be quite skilled, because cats have moving kidneys. PKD is inherited by autosomal dominance, and can lead to the death of the animal. Mostly those cats reach an age between 6-8 years. Frequently the ultrasonography has to be done more than one time to be able to detect cysts with a size of just 2 mm. Cats should not be tested before an age of 7 months, and if the diagnosis is not clear or doubtful, the ultrasonography shall be repeated with an age between  1,5 - 2 years.
Hypertrophic Cardiomyopathy HCM
Maine Coon
This defect can be detected quite often if the cardiac membranes or valvular membranes are thicker than normal, so that the heart rate is higher to transport more oxygen. The test is done by ultrasonography, but the veterinary surgeon must be quite skilled.
Sometimes cats may suffer from shortness of breath, which might be mistaken  as epilepsia. Those animals have to get pills during their whole life, they might become quite old. HCM had been detected first in Maine Coons, but it can appear in all breeds, for example in Persians, Exotics, British shorthair.
Progressive Retina Athrophy PRA
Abvssinian, Somali
Mostly the retina is dissolved, and the cats become blind. PRA had been detected in some Abyssinian lines.
