Rabies in cats is a fatal disease transmitted by the bite of an infected mammal, such as a dog, raccoon, bat, or another cat. Animals with rabies suffer deterioration of the brain and tend to behave bizarrely and often aggressively, increasing the chances that they will bite another animal or a person and transmit the disease. Rabies is rare in many developed countries with more than 99% of all human deaths from rabies occurring in Africa, Asia and South America which report thirty thousand deaths annually. In the United States, cats make up 4.6% of reported cases of rabies infected animals. H5N1. Fungal:Ringworm Parasites:Cytauxzoonosis is a mostly fatal tick-borne disease in domestic cats. It is identified as the blood parasite Cytauxzoon felis. Ear mites are mites that live in the ears of animals. Flea Heartworm Roundworm Tick Toxoplasmosis Genetic disease:Familial renal disease is inherited in Abyssinians and Persians Feline hypertrophic cardiomyopathyHeart valve dysplasia Luxating patella Portosystemic shunt.

Found in Persians and Himalayans. Skin disorder:Cat skin disorders are among the most common health problems in cats. Skin disorders in cats have many causes, and many of the common skin disorders that afflict people have a counterpart in cats. The condition of a cat's skin and coat can also be an important indicator of its general health. Skin disorders of cats vary from acute, self-limiting problems to chronic or long-lasting problems requiring life-time treatment.Cheyletiella is a mild dermatitis caused by mites of the genus Cheyletiella. It is also known as walking dandruff due to skin scales being carried by the mites. Cheyletiella live on the skin surface of dogs, cats, rabbits, and humans. Feline acne Feline eosinophilic granuloma Flea allergy dermatitis Hyperthyroidism Miliary dermatitis (feline eczema) Mange Tumors and Cancer:Bladder cancer Bone cancer Intestinal cancer Liver cancer Lymphoma in animals Mammary tumor Mast cell tumor Nose cancer Skin cancer Soft tissue sarcoma Stomach cancer.

Cat Health
Topics concerning the health and welfare of domestic cats includes infectious and genetic diseases, diet and nutrition and non-therapeutic surgical procedures such as neutering and declawing. Diseases: Infectious disease:An infectious disease is caused by the presence of organisms such as viruses, bacteria, fungi, or parasites (either animalian or protozoan). Most of these diseases can spread from cat to cat via airborne pathogens or through direct or indirect contact. Certain infectious diseases are a concern from a public health standpoint because they are zoonoses (transmittable to humans). Viral:Viral respiratory diseases in cats can be serious, especially in catteries and kennels. Causing one-half of the respiratory diseases in cats. Timely vaccination can reduce the risk and severity of an infection. Feline viral rhinotracheitis is the most important of these diseases and is found worldwide. The other important cause of feline respiratory disease is the feline calicivirus.

Feline viral rhinotracheitis (FVR) is an upper respiratory infection of cats caused by feline herpesvirus 1 (FHV-1), of the family Herpesviridae. It is also known as feline influenza. FVR is very contagious and can cause severe disease, including death from pneumonia in young kittens. All members of the Felidae family are susceptible to FVR, Feline calicivirus (FCV) Chlamydophila felis Feline panleukopenia (FPV) more commonly known as feline distemper is caused by the feline parvovirus, a close relative of canine parvovirus. It is not related to canine distemper. Panleukopenia is primarily spread through contact with an infected cat's bodily fluids, feces, or fleas. Feline leukemia virus (FeLV) is a retrovirus transmitted between infected cats when the transfer of saliva or nasal secretions is involved, for example when sharing a feeding dish. If not defeated by the animal’s immune system, the virus can be lethal. The disease is a virus, not a cancer. The name stems from the fact that the first disease associated with the virus was a form of leukemia.

By the time it was discovered that the virus was not the same as leukemia, the misnomer had already found its way into the vocabulary of pet owners. Feline immunodeficiency virus (FIV), commonly known as Feline AIDS is a lentivirus that affects domesticated housecats worldwide. FeLV and FIV are in the same biological family, and are sometimes mistaken for one another. However, the viruses differ in many ways.

Although many of the diseases caused by FeLV and FIV are similar, the specific ways in which they are caused also differs. Feline infectious peritonitis (FIP)' is a fatal, incurable disease caused by Feline Infectious Peritonitis Virus (FIPV), which is a mutation of Feline Enteric Coronavirus (FECV/FeCoV). The mutated virus has the ability to invade and grow in certain white blood cells, namely macrophages. The immune system's response causes an intense inflammatory reaction in the containing tissues. This disease is generally fatal. However its incidence rate is roughly 1 in 5000 for households with one or two cats.
