Cats including Sphynx are susceptible to many diseases. The main few you should be careful off when geting a kitten are FeLV, FIV, FIP, Corona virus and Hypertrophic Cardiomyopathy(HCM).
FeLV (Feline Leukemia) is a viral disease caused by retrovirus FeLV. The incubation period can last for years and if affects cats of all ages. Disease sympthoms include decreasing appetite ad body weight, lethargy, fever, inflammation of gums, clear mucus,enlarged lymph nodes, persistent diarrhea, different eye conditions just to mention a few.
It is impossible to accurately predict the life expectancy of a cat infected with FeLV. With appropriate care, under ideal conditions, infected cats can maintain good health for many months, although most succumb to a FeLV-related disease within two or three years after becoming infected. If your cat has already experienced one or more severe illnesses as a result of FeLV infection, or if persistent fever, weight loss, or cancer is present, a much shorter survival time expected.
Due to weakaned immune system secondary infections like FIV and FIP may also follow.
There is a vaccine against FeLV.
FIV - Feline Immunodeficiency Retrovirus - Lentivirus(slow virus). Early in the course of infection, the virus is carried to nearby lymph nodes, where it reproduces in white blood cells. The virus then spreads to other lymph nodes throughout the body.
An infected cat's health may deteriorate progressively.
Symptoms include persistent fever, loss of appetite, inflammation of the gums (gingivitis) and mouth (stomatitis), chronic or recurrent infections of the skin, urinary bladder, persistent diarrhea, a variety of eye conditions, slow but progressive weight loss followed by severe wasting late in the disease process.
Some infected cats experience seizures, behavior changes, and other neurological disorders.
It is impossible to accurately predict the life expectancy of a cat infected with FIV. With appropriate care, under ideal conditions, many infected cats will remain in apparent good health for many months or years. If the cat has already had one or more severe illnesses as a result of FIV infection, or if persistent fever and weight loss are present, a much shorter survival time can be expected.
There is no vaccine for FIV invented.
FIP (Feline Infectious Peritonitis) is fatal consequence of coronavirus (FCoV) infection in cats. The majority of cats infected with coronaviruses lead perfectly normal lives. However, if you are thinking of buying a pedigree (purebred) kitten - INSIST that he or she is feline coronavirus (FCoV) free - otherwise you may be buying heartache. At present, there is no treatment for FIP.
Symptoms include upper respiratory infection: sneezing, watery eyes, and nasal discharge. Others give the appearance of having intestinal problems: diarrhea, weight loss and lethargy. Many cats have nonspecific symptoms: intermittent loss of appetite, depression, weight loss, and fever.
There is a vaccine against FIP but it is still contraversial.
FCoV - Feline Enteric Coronavirus is an enveloped single-stranded RNA virus that is highly contagious among cats in close contact. Most catteries are corona positive. This situation is fairly harmless - the problem arises when the virus mutates within a single cat. However only about 5 % of all cats who have contracted the virus, will actually develop FIP. That gives you an average survival rate of 95%.
HCM- Hypertrophic Cardiomyopathy is the most common heart disease found in Sphynx cats. This is a genetic disease that can happen at any time to any breeder regardless of scanning and precautions. HCM is a thickening of the left ventricle wall of the heart. he thickened wall sometimes distorts one leaflet of the mitral valve, causing it to leak.Fluid can leak into the lungs causing heart failure.
Blood clots can form in the left atrium & be carried into the systemic arterial system, most often lodging in the terminal artery, causing paralysis of the hind legs.
Many cats that have heart conditions show no symptoms (ie heart murmur) when checked by a non-specialist vet.
Respectable breeders are proactive and scan their breeding cats annually at board certified cardiologists to ensure they are breeding healthy cats.
A cat with hypertrophic cardiomyopathy may display no symptoms at all, but die suddenly and unexpectedly. Symptoms may include:lethargy, anorexia, weight loss, rapid, laboured and noisy breathing, decreased activity, congestive heart failure, irregular heart rhythm, heart murmur, gagging, lameness or paralysis of the hind legs.
