Infected cats may appear normal for years. However, infection eventually leads to a state of immune deficiency that hinders the cat’s ability to protect itself against other infections. The same bacteria, viruses, protozoa, and fungi that may be found in the everyday environment–where they usually do not affect healthy animals–can cause severe illness in those with weakened immune systems. These secondary infections are responsible for many of the diseases associated with FIV. The primary modes of FIV transmission are deep bite wounds and scratches, where the infected cat’s saliva enters the other cat’s bloodstream. FIV may also be transmitted from pregnant females to their offspring in utero though it is rather rare.
Feline leukemia is a cancerous disease caused by feline leukemia virus (FeLV). FeLV causes diseases other than leukemia including other cancers and immunodeficiency. Cats may not start to show signs of disease for months or years after being infected with FeLV. Infection with FeLV is a major cause of illness and death in domestic cats. Feline leukemia virus (FeLV) is contagious among cats. Unlike many other viruses that enter specific cells in the body and destroy them, FeLV enters certain cells in a cat’s body and changes the cells’ genetic characteristics. This permits FeLV to continue reproducing within the cat each time infected cells divide. This allows FeLV to become dormant (inactive) in some cats, making disease transmission and prognosis (outlook) difficult to predict.
Both FIV/FeLV blood test can be done at the clinic and results will be available in 10 mins.
