Feline Immunodeficiency Virus (FIV)
Some consider feline immunodeficiency virus (FIV) to be the cat equivalent of HIV in humans. FIV causes a highly contagious and potentially fatal retroviral infection that weakens a cat’s immune system, making the cat susceptible to illness and secondary infection. Also, like HIV, FIV reduces the ability of the immune system to fight infection. Learn more about FIV and your cat >>

Feline Leukemia Virus (FeLV)
Like FIV, feline leukemia virus (FeLV) causes a highly contagious and potentially fatal retroviral infection that weakens a cat’s immune system. Feline leukemia can be easily spread from cat to cat through casual contact. Learn more about FeLV and your cat >>

Feline Heartworm
Heartworm is spread by mosquitoes that ingest the baby heartworms (also known as microfilaria) from an infected source and carry them to a new source. Upon entering a new host through the mosquito bite, heartworm larvae will migrate. They usually find their way into the blood vessels around three or four months later. Heartworms may cause a variety of problems including inflammation and injury to the lungs and airways. Learn more about feline heartworm >>
