What is FelV?

WHAT IS FELINE LEUKEMIA?

This is a serious disease in cats, caused by a viral infection that attacks and weakens a cat's immune system, leaving it unable to fight other infections.  It's also a complex disease, of which leukemia (cancer of white blood cells) and cancerous tumors are only a small part.  Various other related but non-tumorous diseases are also involved such as...

• anemia
• atrophy of the thymus gland
• ulcers of the mouth
• skin lesions
• reproductive problems (miscarriages and weak or dying kittens: fading kitten syndrome)
• chronic digestive problems (diarrhea, constipation, loss of appetite)
• respiratory problems
• chronic fever
• chronic urinary bladder infections
• enlargement of lymph nodes
• excessive drinking or urination
• jaundice
• lethargy
• neurologic abnormalities/loss of coordination

Although not all cats develop the disease at the time of exposure, they may still become potential carriers, infecting other cats.

HOW IS FELINE LEUKEMIA CONTRACTED?

Feline leukemia is spread by direct contact with infected cats.  It's usually transmitted in the saliva, but low levels of virus can also be found in urine and feces.  Licking, biting and sneezing are common forms of transmission.  Food and water dishes and litter boxes are likely sources of infections, if healthy cats share them with infected cats.

WHAT CAN YOU DO TO PREVENT FELINE LEUKEMIA?

The best solution is to see your veterinarian and have your cat or cats tested for FelV then get them vaccinated if they test negative for the disease as there is no treatment or cure for the disease once contracted.  Also, limit or eliminate all contact with other cats.  This however isn't always possible or practical.  Newly acquired cats should always be tested for FelV before being introduced to the household.
