Anything For Animals

The Feline Leukemia Virus is also known as FeLV and can infect any cat that hasn’t been vaccinated for this virus.

The virus is associated with lympho-sarcoma (lymph gland tumours) but can also affect the thymus, spleen and gut wall.  As the lymph glands are affected, this can lead to a form of immuno-suppression, making the animal prone to other infections.

Symptoms of Feline Leukemia:
An un-vaccinated cat will start to show symptoms of feline leukemia only after about 3 years!  It has a very long incubation period - although laboratory tests before this time can confirm the disease.

If your cat started showing symptoms they would probably include a high temperature initially, with noticeable lethargy (sleeping more than usual or not wanting to play and chase as normal).  It is possible that there would be a noticeable lack of appetite, although this could possibly be very difficult to spot when many cats are feeding from the same bowls.  

It is possible you will notice swollen lymph glands, but this would only be found with a proper check of the appropriate areas - they wouldn’t be felt with just regular stroking!

Persistent dental problems and gingivitis are common with this type of long-term infection.

If the virus remains active in the cats body, then the cat will be at risk of developing further disease.

Noticeable (clinical) signs of Feline Leukemia vary depending on where the Feline Leukemia virus is replicating - making more of itself - as this organ will be most affected and will probably develop a tumour.  The Feline Leukemia virus usually also involves the red blood cells in some way and can lead to related signs such as anaemia and immuno-suppression. 

If only found present late on in a cat, symptoms may well be secondary infections like bladder problems (cystitis) or other infectious diseases as the cat’s body can no longer defend itself from attack.

A positive diagnosis would need a blood or saliva test in a laboratory.

Is Feline Leukemia contagious?
Yes, and multi-cat households and breeding farms are most at risk.

A persistently infected cat can pass it on to all other cats in the household, and the only effective action is to permanently remove the infected cat from house. 

The virus is passed on through close intimate contact such as intercourse, saliva and blood.  So cat fights, same dish feeding and breeding can all spread the disease.

Feline Leukemia Treatment:
There is no cure for Feline Leukemia, and surviving Feline Leukemia is likely to be treatment that is symptom related, so removal of tumours, a course of anti-biotics for infections, etc.  The cats life will no doubt be shortened and possibly filled with illness.  It can sometimes shorten the cats life to just a few years after initial symptoms were spotted.

Sadly, the readily available vaccination would have prevented initial infection with the virus anyway, but not everyone vaccinates regularly, thinking it ‘won’t happen to them’.

In addition, make sure that any new cats entering your home or breeding cattery have been tested clear for FeLV and are vaccinated before putting your own cats at risk.
