FeLV is one of the most serious viral infections in cats. Once infected, it weakens the immune system, making cats vulnerable to many other illnesses. But with the right care and early support, many FeLV-positive cats can still enjoy a happy life.

What is FeLV?

Feline Leukaemia Virus (FeLV) is a retrovirus that attacks the immune system and bone marrow. It can cause:

• Immune suppression (leading to frequent infections)

• Anaemia

• Lymphoma and other cancers

• Reproductive issues

Some cats fight off the virus completely, others carry it for life. Over time, their ability to resist infections declines.

How FeLV Spreads

FeLV spreads through:

• Saliva (grooming, sharing bowls or toys)

• Nose-to-nose contact

• Bites

• Blood

• Urine or faeces

• From mother to kittens (during pregnancy or nursing)

FeLV is more common in multi-cat households, outdoor cats, and unneutered populations.

Symptoms to Watch For

FeLV often has no symptoms early on. As it progresses, you may see:

• Lethargy

• Loss of appetite

• Weight loss

• Pale gums (anaemia)

• Fever

• Repeated infections (skin, respiratory, mouth or gut)

• Enlarged lymph nodes

• Breathing issues

• Tumours or swellings

Regular vet checks help catch the disease early.

Diagnosing FeLV

FeLV is diagnosed with a simple blood test. Your vet may recommend:

• ELISA (snap) test for initial screening

• PCR or IFA test to confirm diagnosis

Occasionally, retesting is needed if the cat’s exposure was recent.

Living with FeLV

There is no cure, but with good care, many FeLV-positive cats can live for months or even years without serious illness.

Key management steps:

• Keep your cat indoors to reduce risk of exposure to infections

• Neuter to prevent breeding and reduce stress

• Limit contact with FeLV-negative cats

• Promptly treat any infections or health changes

• Regular veterinary check-ups to monitor progress

Stress reduction is very important for FeLV cats.

The Role of Diet

A natural, raw diet supports immune health, gut balance, and overall resilience. Key benefits include:

• Fresh, bioavailable nutrients

• High-quality protein diet
  

• Gentle on digestion

💡 Poppy’s Tip: Our naturally balanced raw cat meals provide highly digestible and can support to help FeLV cats stay strong for longer.

Holistic Support

Holistic therapies can also play a role:

• Homeopathy (under professional guidance)

• Acupuncture

• Herbal support (such as astragalus, echinacea or medicinal mushrooms)

• Probiotics to support gut and immune function

• Pheromone diffusers to reduce stress

Always work with experienced practitioners when using complementary therapies.

Top 5 Takeouts

• FeLV is a viral disease that weakens the immune system over time.

• It spreads through saliva, blood and close contact with infected cats.

• Early diagnosis and careful management can extend quality of life.

• Raw feeding supports the immune system naturally.

• Holistic support may help reduce stress and strengthen defences.
