PKD is the abbreviation
of Polycystic Kidney Disease: Polycystic Kidney Disease.
It is a hereditary condition in which large fluid-filled cavities gradually develop in the kidneys. In view of heredity, the disease is more common in certain breeds and families: PKD is particularly common among Persians.
Also cats from
other breeds where Persians were bred, such as the Sacred Birman, the Ragdoll and the British
Shorthair, can show PKD.
The development of the cavities gradually reduces the function of the kidneys. The cavities, as it were,
oppress the healthy kidney tissue and gradually signs of chronic
renal insufficiency develop.
The first symptoms usually occur in middle age when the animals are 6 to 7 years old.
The diagnosis is made with the aid of an ultrasound. The cavities are clearly visible with this research.
With DNA research one can now
determine PKD if there are no cavities visible in the kidneys during ultrasound.
The treatment of
PKD will be the same as for chronic renal failure.
The animals receive a special low-protein diet to relieve the kidneys. This can be supplemented with medication.
Unfortunately, there is no cure for PKD and the animals will
eventually succumb to their effects.
PKD is a hereditary disease. It is therefore very important to exclude affected animals from the culture.
Persians used for breeding must be tested for PKD before breeding.
FIP or Feline Infectious Peritonitis is a complicated condition caused by a
It is suspected that the disease is actually caused by the Feline Enteric Corona Virus (FECV).
This is a relatively harmless virus that can cause diarrhea in cats and where the cat normally cures quickly. It is very contagious and there are cats that are carriers of this virus and therefore continuously excrete, without symptoms.
Apparently this FECV virus mutates fairly easily. In about 1 in 50 infected cats, the genetic material of this virus can change to form the FIP virus. This virus is not contagious, but causes serious symptoms.
This mutation seems to be more common in stress and in cats with reduced immunity (such as Fiv and FeLV!).
FIP exists in 2 forms: the wet and the
The wet form of FIP is quite typical: the cats get huge fluid outflows in the abdomen and / or chest cavity. The abdomen can be very swollen and the moisture that the veterinarian gets out has a typical yellow and draughty appearance. Moisture in the chest cavity can cause severe breathing problems.
The dry form of FIP is characterized by the formation of plaques throughout the body. These can occur in all organs and provoke inflammatory reactions there. The kidneys, liver, lungs, lymph nodes, intestines, brain and eyes can be affected. The animals then show signs of inflammation of these organs.
Fever often occurs and cats with FIP are listless, lose appetite and lose weight.
Both forms are deadly. The survival time of the wet form is several weeks, from the dry few months.
diagnosis is made based on clinical signs and blood tests. In the moist form, the abdominal or chest
cavity is also examined.
A definitive diagnosis can only be made by examining tissue particles or by autopsy.
One can stretch the life of the
animal through hospitalization and aggressive therapy, but eventually the animal will die with FIP.
Bad: the cat will die.
There is a vaccine available but this is never administered, due to its poor functioning and the low incidence of FIP.
disease leucose occurs as a result of an infection with the Feline Leucemie Virus (FeLV). FeLV is mainly transmitted via saliva from infected cats, but also through urine and
The transfer via saliva has as a consequence that co-living cats eating from each other's crib are often both contaminated. Not all cats that come into contact with the leukemia virus actually get the disease leucose. It has been established that mainly young kittens are susceptible to the development of the disease.
Older cats seem to develop a defense against the virus in many cases.
Infection with FeLV causes
leukemia: tumors of the white blood cells. This can result in the cat getting tumors,
anywhere in the body. Often the internal organs such as liver, lungs, spleen and kidneys are
affected. Leucosis is a common cause of tumors in cats.
Due to the disease, the white blood cells, which are responsible for the immune system, can no longer perform their actions properly. This results in a clinical picture that shows great similarities with FIV or Kattenaids: a reduced resistance characterized by chronic inflammations and infections.
The diagnosis of leucosis is made by means
of a blood test.
This test is often combined with the FIV test, because the clinical picture of both diseases is very similar and because infections with these viruses often occur together.
There is no cure for
The secondary infections can be controlled with antibiotics.
Tumors can be treated with medication that suppresses the growth of the tumors, but these often also have a negative effect on the already reduced resistance of the cat.
Bad: leucosis is deadly. Usually cats die within 1 to 3 years.
In contrast to FIV, there is a vaccine available against the leukemia virus. This vaccine greatly reduces the chance that the cat will develop the disease, but does not completely rule out this opportunity.
