Cat Diseases (Panleukopenia)

The oldest vaccine we have is fighting panleukopenia, a form of infectious enteritis. This is a very serious viral form of cat diseases can lead to death in a short time. The extremely aggressive pathogen affects mainly young cats, which is why the vaccination is of greater importance; for the later years, however, the disease is hardly a risk, since with regular vaccination sufficient protection exists.

Cat flu

The situation is different with the cat flu, compared to humans and having an incorrect name. It can often take much heavier forms than the human cold and also is not caused by flu viruses. You can, therefore, be sure that you will not catch your cat with your cold and vice versa. They are mainly two pathogens causing cat flu: the calicivirus and the herpes virus. Once a cat is affected, it often remains a virus carrier throughout its life. It always has to deal with running nose and watery eyes (especially cats with flat noses such as Persian cats). In more severe cases, the nasal mucous membranes are damaged, resulting in chronic rhinitis. Then the nose clogs, breathing in creates a noise,

In addition to the two mentioned there are other pathogens. they can lead to milder forms of the rather broad term cat flu. Here is especially the Chlamydia to call. These are bacteria-like microbes that cause eye tears and against which there is recently a vaccine. This is used mainly in infested cat colonies.


Fortunately, we now have a vaccine against cat leukosis, a very common and dangerous disease. Again, it is an infection that, although transmitted at a young age, remain latent for a long time and may come later to the outbreak. In a study of about 6000 serums, which was carried out in 1994 in the Federal Republic of Germany, the pathogen was found in more than 10 percent of healthy and more than 18 percent of the sick animals. The virus leads to the following four diseases:

– Severe, sometimes fatal anemia

– infertility

– Damage to the immune system with increased susceptibility to secondary infections

– Training of tumors, especially lymphosarcomas, a cancer of the white blood cells

Due to the special mode of action of leukemia viruses, tumorous degeneration of white blood cells is the most common tumor disease. In many cats, it develops only in old age, and the virus is often no longer detectable in the blood. However, it has linked to the genetic substance of the cells. In this way, there is a danger that it will be passed on to future generations. However, it is to be hoped that vaccines that are as widespread as possible will largely reduce the incidence of this disease.

Feline’s immunodeficiency virus

Unfortunately, although viruses are the simplest form of life, it is extremely difficult to combat them because they have the ability to change and quickly develop new forms. No sooner had science found a vaccine against the causative agent of feline leucosis than it faced a new virus: the causative agent of feline immunodeficiency, similar to the AIDS pathogen. This newcomer has managed in a short time to prevail so far in our cat population that it occurs as frequently as the leucosis virus. It damages the immune system, which, just like AIDS, can affect in many different ways. The cat loses its resistance and suffers from secondary infections that would normally hardly affect her.

There is currently no vaccine against the new pathogen. Since the cat can serve as a model for the control of the human form of this disease, intensive research is underway in the hope of getting closer to winning a vaccine for cats also an AIDS vaccine. The Glasgow Veterinary College owes its leading role in UK AIDS research to nothing more than the fact that it had originally worked on the development of a vaccine against cat leukemia and feline immunodeficiency. Incidentally, these diseases are not transferable to humans.

Feline Infectious Peritonitis 
(FIP, contagious ascites)

The contagious ascites is part of viral infectious cat diseases, against which there is, unfortunately, no remedy. According to current knowledge, the virus initially infects the gastrointestinal tract. Here it can cause diarrhea, in some cases the genetic information of the virus changes, and it can now also infect other cells of the body and trigger FIP. It usually diseased either young or old cats. The so-called dry form is rather unspecific with fever, reduced general condition, inflammation of the eyes, changes in kidneys and inflammation of the meninges. The more frequent wet form is also associated with nonspecific changes such as fever and fatigue, but its typical feature is an increasing increase in volume of the abdomen with simultaneous emaciation by free, protein-containing fluid accumulates in the abdomen. There is a vaccine against FIP available recently, which is not yet quite satisfactory.


In cats, toxoplasmosis can be completely unrecognized as intestinal cat diseases, in which for animals and humans infectious substances (cysts) are excreted over a short period of time (a few weeks) with the feces. The more common route of infection, however, is via the intake of raw meat, in which Toxoplasmosezysten can be located (in humans mostly pork, in the cat prey animals). If the cat never gets raw meat and has no contact with excreta of other cats, then it will not get infected. Again, this is a reason to sanitize cat feces hygienically. The toxoplasmosis pathogen (Toxoplasma gondii) is a single-celled animal. It proliferates in the cells of higher animals and causes disease by destroying the affected cells. Noteworthy is the low host specificity of Toxoplasma. Which means that all pets, and even humans, can be infected with Toxoplasma except for wild animals.

Despite the frequent infections, a detectable, severe toxoplasmosis disease is extremely rare. In humans, a toxoplasmosis infection usually proceeds without appearance. The affected organism forms antibodies and thus suppresses the disease. However, toxoplasmosis represents a significant risk for unborn children whose mothers are first infected during pregnancy. In pregnant women, therefore, a certain caution in dealing with cats is appropriate. For safety, they can have a toxoplasmosis antibody titre determined in human serum. This is the maximum dilution of a blood serum sample at which the toxoplasmosis antibodies can barely be determined. A titer of 1: 100 means that the dilution of 1 part of blood serum in 100 parts of dilution liquid antibodies are still detected. The higher the titer, the more antibodies are in the blood.

Even if the human organism has a sufficiently high antibody titer, toxoplasmosis pathogens remain as so-called cysts in various body tissues. But they can not multiply, that is, they do not produce disease. Almost all people who often have contact with animals or like to eat raw minced meat have sufficient antibody titers against toxoplasmosis.


Rabies is also known to be transmissible to humans. How do you get to such a terrible cat diseases? The infection takes place exclusively via a salivary infection. Whereby the saliva of the sick animal has to enter the bloodstream. This is usually done by bites. Theoretically, it is also possible that infected saliva on a small wound on the hand penetrates into the body. In practice, this is unlikely.
Rabies vaccination is possible in cats from the eighth week of life.

When travelling with the cat abroad, the rabies vaccination rule. Inquire in advance at the veterinarian, how long ago she must or may be. There is no remedy for this extremely rare disease, neither in veterinary medicine nor in homoeopathy. From the time of infection to the onset of the disease, weeks, even months, can pass. Rabid cats are more prone to “silent” rage, and shy animals are famous for their great confidence. They are easily excitable, photophobia, water-shy and salivate strong. Then paralysis occurs, later paralysis of the legs, later on the whole body. The veterinarian is obliged to put any rabid cat to sleep immediately. In this case, it means a release for the poor animal. If, for once, rabies is not “silent” in the cat, it can start and bite the person before the paralysis starts, which of course also causes them to become infected.
