Feline leukemia virus (FeLV) is a retrovirus that infects cats. (wikipedia.org)
FeLV can be transmitted from infected cats when the transfer of saliva or nasal secretions is involved. (wikipedia.org)
Because FeLV is cat-to-cat contagious, FeLV+ cats should only live with other FeLV+ cats. (wikipedia.org)
FeLV is categorized into four subgroups, A, B, C and T. An infected cat has a combination of FeLV-A and one or more of the other subgroups. (wikipedia.org)
Although it is thought that virus protein has to be present to induce lymphomas in cats, newer evidence shows that a high percentage of FeLV-Antigen negative lymphomas contain FeLV-DNA, indicating a "hit-and-run" mechanism of virus-induced tumor development. (wikipedia.org)
Once the virus has entered the cat, there are six stages to a FeLV infection[citation needed]: Stage One: The virus enters the cat, usually through the pharynx where it infects the epithelial cells and infects the tonsilar B-lymphocytes and macrophages. (wikipedia.org)
Cats infected with FeLV can serve as sources of infection of FeLV-A. Cats can pass the virus between themselves through saliva and close contact, by biting another cat, and (rarely) through a litter box or food dish used by an infected cat. (wikipedia.org)
Once a cat has been infected with FeLV-A, additional mutated forms of the original FeLV-A virus may arise, as may FeLV subgroups B, C and T. In addition to domestic cats, some other members of Felidae are now threatened by FeLV (e.g. lynx and Florida panther). (wikipedia.org)
Approximately 0.5% of pet cats are persistently infected with FeLV, but many more pet cats (>35%) have specific IgG antibodies which indicate prior exposure and subsequent development of immunity instead of infection. (wikipedia.org)

Only adult cats can transmit FeLV to others. (magazinehub.net)
The symptoms of FeLV are often similar to other illnesses that cats can get. (magazinehub.net)
Knowing the symptoms can help determine if your cat is suffering from FeLV. (magazinehub.net)
If you live in an area where there are many other cats and the population density is high, it's also more likely for your pet to be exposed to FeLV through its contact with other cats. (magazinehub.net)
This means that if your cat is infected with FeLV, he or she could spread the virus by biting, scratching, or even licking you with an infected mouth. (magazinehub.net)
A cat with FeLV can spread the virus through its saliva, blood, and nasal secretions, as pointed out in an article published on the NCBI website. (magazinehub.net)

What is the feline leukemia virus (FeLV)? (petcreeks.com)
Feline leukemia virus (FeLV) is a virus that infects cats and is one of the most common infectious diseases in cats in the United States. (petcreeks.com)
FeLV is transmitted between cats via infected saliva and urine and can be spread through direct contact with these body fluids, mutual grooming, shared litter boxes, and more. (petcreeks.com)
FeLV is a retrovirus belonging to the coronavirus subfamily, which means it is a cancer-causing virus that only affects cats. (petcreeks.com)
Feline leukemia virus (FeLV) is typically spread from cat to cat via close contact with infected and non-infected cats. (petcreeks.com)
FeLV can be transmitted from an infected mother cat to her kittens, either before they are born or while they are nursing. (petcreeks.com)
It is important to note that all cats can become infected with FeLV, though kittens or cats with already weakened immune systems are more susceptible. (petcreeks.com)
Allowing an unvaccinated cat to be unsupervised while outdoors may increase their risk of contracting FeLV. (petcreeks.com)
Because of this, it's crucial to test pregnant cats for FeLV and to keep infected moms away from their young. (petcreeks.com)
FeLV can be spread through contaminated feces and urine when a cat shares a litter box with an infected cat. (petcreeks.com)
This is because FeLV can infect white blood cells, lowering immunity and increasing the risk of infection in cats. (petcreeks.com)
Sharing water and food bowls with a cat that is infected can spread FeLV through saliva. (petcreeks.com)
Through intimate touch, FeLV can spread from one cat to another. (petcreeks.com)
Cats who spend a lot of time outside have a higher chance of coming into touch with FeLV-positive cats. (petcreeks.com)
It is advised to have cats frequently tested for FeLV and to keep up with their vaccines if outside exposure cannot be avoided. (petcreeks.com)
Blood transfusions can result in the transmission of FeLV, thus it's crucial to make sure that any blood products given to cats are free of the virus. (petcreeks.com)
It's crucial to request FeLV-free blood if your cat needs a transfusion. (petcreeks.com)
FeLV infection is more likely to occur in cats with compromised immune systems. (petcreeks.com)

We have recently heard that not all vets automatically vaccinate against feline leukaemia virus (felv) when administering the annual booster for cats. (github.io)
Feline infectious enteritis (fie), cat 'flu, and feline leukaemia virus (felv). (github.io)
By applying sensitive molecular assays, efficacious commonly used felv vaccines that protect cats from antigenaemia were found not to prevent proviral integration and minimal viral replication after challenge. (github.io)
Feline leukaemia virus, or felv, is a virus that causes a fatal disease by affecting the immune system. (github.io)

Background - Feline leukemia virus (FeLV) is a retrovirus related to murine leukemia virus that has existed among feral cats for tens of thousands of years before its discovery in 1964 (Jarrett, et al. (treatfip.org)
1964). FeLV infection occurs mainly among cats under 3-8 years of age (reviewed Pedersen, 1998, 1991). (treatfip.org)
1977). FeLV infection in nature usually occurs after cats are old enough to socialize and the primary phase of infection is either inapparent or transient and ends with a long-lasting immune response in 95% or greater of cats. (treatfip.org)
FeLV-associated diseases occur predominantly in the small group of cats with persistent infection. (treatfip.org)
FeLV disease in feral cats raised no alarms prior to its discovery and any associated mortality went unappreciated among the spectrum of maladies befalling feral cats. (treatfip.org)
Therefore, what we know about the pathogenesis of FeLV infection in feral cats initially came from studies done in the 1970's and 1980's on groups of household cats and laboratory infections (reviewed Pedersen, 1998, 1991). (treatfip.org)
Epizootiology - FeLV appears to have entered unknowingly into owned cat populations from nature prior to the 1960's and rapidly increased in incidence. (treatfip.org)
FeLV was identified as a major cause of disease in owned cats, retrospectively in the 1960s and prospectively in the 1970's and 1980's. (treatfip.org)
What caused the panzootic of FeLV infection and disease among owned cats? (treatfip.org)
The end of the FeLV panzootic came with the widespread "testing and removal" of viremic cats as documented by Weijer and colleagues (1986). (treatfip.org)
It is noteworthy, that FeLV infection is no longer a major disease problem in managed multi-cat situations and household pets. (treatfip.org)
Cats with persistent FeLV infection will ultimately develop several primary and secondary diseases that are usually fatal. (treatfip.org)
Since infection in nature occurs mainly in younger cats, and most die within 3 years, few FeLV infections in nature are seen in cats older than 5-8 years. (treatfip.org)
This one-day event has a unique focus on cats with feline leukemia (often referred to as FeLV) and what animal shelters, veterinarians, caregivers, and pet parents can do to support them in their journey. (katzenworld.co.uk)
Feline leukemia (FeLV) is a virus that weakens your cat's immune system. (rickordsanimalhospital.com)
The FeLV vaccine will help prevent your cat from developing feline leukemia, but it does not offer an absolute guarantee that your cat will never get the virus. (rickordsanimalhospital.com)

As it's passed through saliva and blood it's mostly caught from from a cat fight or licking during mutual grooming. (alltodowithcats.com)
Because feline leukemia can be transmitted via blood, saliva, and even urine and feces, it's important for cats without the virus to be kept separately from those who have it. (meow.af)
