Feline leukemia virus
Are you concerned about feline leukemia and the possible consequences it could have on your cat? Here are some crucial details about the deadly virus for pet owners.
FeLV, sometimes called the feline leukemia virus, is an international retrovirus that affects cats. This cat disease is the second-leading cause of death in cats, killing 85% of those with the condition within three years (after trauma).
Feline leukemia damages the immune system similarly to FIV, which increases a cat’s susceptibility to additional, possibly fatal infections. The good news is that most felines who catch FeLV will be able to fight it off or get rid of it on their own, which accounts for roughly 70% of cases.
Let’s go over the virus in more detail and go over what you can do to help prevent infections.
Increasing Cat Leukemia
FeLV-infected cats also secrete the virus through their feces, urine, and blood in addition to through their saliva and nasal secretions. Mother cats may also transmit the virus to their kittens through their milk or before delivery.
The virus can be transferred from cat to cat through bites and grooming. Sharing water and food dishes and litter boxes is another way of transmitting disease.
However, the virus only endures in the environment for a brief period of time once it has been exposed to a cat (a few hours under typical circumstances).
Symptoms of Feline Leukemia
FeLV has been identified by Cornell University College of Veterinary Medicine as “the most common cause of cancer in cats.” Infection can impair your pet’s immune system, which increases their susceptibility to a number of infections in addition to these negative effects. The infection may also result in blood issues.
A cat may not initially exhibit any symptoms, but after a few weeks, months, or even years, his health may start to progressively decline or he may endure recurrent illnesses in between times of health.
During the initial stage of the illness, or the main stage, some felines may mount a successful immune response. These felines may be able to eliminate FeLV from their blood, halting the transmission of the illness.
The secondary, or latter, stage results in a persistent infection of the tissue and bone marrow. At this point, the point of no return, the majority of infected cats will have the infection for the rest of their lives.
There are many signs of feline leukemia, some of which include:
- The whites of the cat’s eyes and mouth are both yellow.
- Pale gums and mucous membranes
- A mouth and gum infection
- An expansion of lymph nodes
- At first, there is a slow but steady weight loss, and then there is a rapid wasting.
- Diminished appetite
- Skin, throat, and bladder infections
- Bad condition of the coat
- Fever
- Becoming more and more lethargic and weak
- Diarrhea
- Difficulty breathing
- Issues with infertility in females who haven’t had sex
- Abnormal behavior, neurological conditions, and convulsions
- Eye issues
Leukemia treatments for cats

In order to stay healthy and prevent more infections, FeLV-positive cats may benefit from preventative medication and twice-yearly checkups, but 85 percent of persistently infected cats will die from the virus, usually three years after being discovered. FeLV cannot be cured, although secondary infections can be treated as they appear.
Taking steps to prevent feline leukemia
It’s important to keep in mind that a cat might have a condition even though he appears to be healthy. He might also pass the illness on to another cat if he has it. Therefore, having your cat tested before exposing him to the other cats in your feline family is one method to prevent transmission usuallysion.
You should keep your cats as confined to the house as possible to avoid them coming into contact with other cats who might be FeLV carriers.
Although there is a FeLV vaccine, you should discuss the advantages and disadvantages of immunizing your cat with your veterinarian. They can direct you in the right direction because they are the authorities on your pet. Consider taking care to prevent exposure because not all cats that receive the FeLV vaccine will be immune to it.
