Which animal is most commonly affected by feline leukemia virus (FeLV)?

Feline leukemia virus (FeLV) primarily affects cats, making them the most commonly affected species. FeLV is a retrovirus that can lead to various health issues in infected cats, including immune system suppression, increased susceptibility to other infections, and a higher risk of certain types of cancers. The virus is transmitted through saliva, which means that close contact between cats, such as grooming or sharing food and water bowls, can facilitate its spread.

While dogs can be affected by a variety of viruses, they are not susceptible to FeLV. Similarly, rabbits and cattle have their own sets of viral infections but do not contract FeLV. Thus, recognizing that FeLV is specific to cats helps emphasize the need for proper vaccination and management strategies for feline health. This knowledge is crucial for veterinary assistants when educating pet owners about the risks and prevention of feline leukemia virus.
