FIV is a virus in cats that is similar to the human virus, HIV (Human Immunodeficiency Virus). However, FIV does not infect humans and HIV does not infect cats.
Signs of FIV are varied but usually result from a weakened immune system and therefore a vulnerability to other infections. Once disease develops infected cats may:
- simply seem “off-colour” or have a high temperature
- lose weight
- develop tumours
