Feline Immunodeficiency Virus (FIV): An infection with the feline immunodeficiency virus (FIV) is the cause of the sickness known as “feline AIDS,” which is a disease that damages the immune system of cats. Their natural defense against the onslaught of other illnesses may be substantially compromised, in a manner strikingly similar to that of AIDS in humans. This sickness cannot be passed on to people since it is not contagious.
The Feline Immunodeficiency Virus (FIV) is nearly often passed on to other cats via the bites of infected cats. Saliva contains the virus that is responsible for causing the sickness.
Some infected cats may not show any symptoms of the sickness, while others will exhibit the early signs of the illness, which include fever, lack of appetite, diarrhoea, lethargy, and enlarged lymph nodes. As the condition continues, signs like as weight loss, ulcers in and around the mouth, eye lesions, poor coat, and persistent infections may appear. Eye lesions may also cause vision problems.
After a while, the immune system can no longer effectively defend the body against additional illnesses and infections. As a direct consequence of this, the cat might end up passing away from one of these later illnesses.
