Feline Leukemia is an immunodeficiency disease that is caused by a retrovirus and only affects cats. The disease is becoming more uncommon with time thanks to medical advancement and the development of vaccines. Presently, less than 1% of healthy cats contract Feline Leukemia Virus and if diagnosed at an early stage, the spread of infection from one cat to another can be effectively contained.
In a Hurry? Here are Our Top Choices
As explained by the Cornell Feline Health Center, the Feline Leukemia virus is a transmittable virus that can be transferred from an infected cat to a healthy cat via salvia, nasal secretions, urine, feces, cat bites, and through sharing of meals. Often, healthy looking cats that are asymptomatic can be carriers of this virus and infect kittens and adult cats with weak immune systems.
As this is an immunodeficiency virus that attacks the cat’s immune system, cats with feline leukemia virus become more susceptible to infectious diseases like bacterial infections and digestive disorders. Therefore, it is recommended that you should take your kittens and cats to veterinary clinics on a regular basis and get them vaccinated.
The Risk Factors for Feline Leukemia
Even though all healthy cats are at a risk of contracting feline leukemia virus, some cats are at a higher risk than others. Kittens and young cats have a more sensitive immune system as compared to adult cats. The older the cats get, the more resistant they become to feline leukemia virus. However, even older cats with weak immune systems are at a higher risk as compared to healthy adult cats.

Cats that wander outdoors are also at a greater risk of getting infected. This is because, they have more chances of coming into contact with infected stray cats, and either through cat bites during fights, or secretion of bodily fluids, the virus can transfer from the infected stray cat to your wandering pet cat.
Vets advise that when you adopt kittens or cats from an animal shelter or cattery, first take them for vaccination because when housed together with other cats, there is a high chance that your new member of the family was exposed to the virus and got infected. A timely visit to the vet will not only help in early diagnosis but can also prevent future ailments through vaccination.
