Young cats, especially those under 4 months of age, have the least ability to mount an effective immune response and are most susceptible to FeLV. All cats/kittens should be tested whether ill, exposed to a FeLV positive cat or a new cat to a household.
Euthanasia should be addressed on an individual basis in consultation with your veterinarian
Allowing your kitty to live with is a viable option even if you have other kitties at home, even if your other kitties may or may not test positive. But they should never be exposed to other kitties nor under any circumstances should they be allowed to roam outside.
Caring For Your FeLV Positive Kitty
Treating your kitty with good supportive and loving care is so important even though there is no specific treatment or no known controlled cure. Always...Keep kitty indoors and...
Give their regular vaccinations with killed virus vaccines (no feline leukemia vaccine)
Control parasites, such as fleas, earmites, intestinal parasites.
Early and aggressive treatment of any symptoms that appear (see above symptoms)
Tests used have a small percentage of false positive results – 1-5%
Test look for viral antigens not antibodies
Kittens can be tested at any age because maternal immunity does not interfere with test
ELISA is the most common screening test
IFA (immunofluorescent antibody) test is the most common confirmatory test
Test done on tears or saliva are unreliable, it should be performed on a blood sample
All cats/kittens should be tested whether ill, exposed to a FeLV positive cat or a new cat to a household.
Vaccination for FeLV
Does not affect test results
Vaccines are about 85% effective in preventing infection with feline leukemia virus
FeLV vaccines are designated as non-core vaccines and recommended only for those cats whose lifestyle places them at risk for FeLV – which include out door cats, indoor/outdoor, feral, cats in open multi-cat households, FeLV-positive households or where FeLV status of all resident cats is not known.
Therapies that have helped FeLV Kitties.
AZT – Anti-viral drug- shows some promise – but has many side effects
Combining AZT with interferon or interferon and another immunostimultant – Propionibacterium acnes.Immunotherapy: Staph protein A – (ProZyme)- digestive enzyme (1/4 tsp per 1 cup food)
Immunoregulin: Not recommended once cat develops any type of lymphosarcoma, cat must
be taken off Prednisone at least a week before starting treatment unless
severe anemia is noted. It is a biological product which can stimulate the
immune system to defend itself against disease. It is administered
intravenously giving 2 injections a week for one or two weeks, then one
injection a week until symptoms are alleviated.
Acemannan: (Carrisyn) – Oral doses are not yet available4.
Baypamum: Not available in North America due to FDA concerns. (it’s cultured on
Bovine kidney tissue) possibility of MDC. Studies are being done at Bayer
Company in Kansas.
Moducare and Hyproxin: Plant “fats” present in every single plant (fruits and vegetables). Chemically
very similar to the animal fat, cholesterol but totally different in biological
functions. They modulate the functions of the T cells - specialized cells
which fight off offenders which live inside the host’s cells (e.g. Viruses,
certain bacteria, etc.
Dimethylglycine (DMG): A tertiary amino acid, a derivative of glycine and a natural component of
animal and plant metabolism. It supports transmethylation processes through
its ability to give up its methyl groups to help produce Sulfur-
adenosylmethionine (SAMe)-pet formula only, do not split or crush. A very
good generic brand is Denysol. It also protects against many forms of
physical, metabolic and environmental stress. This is a great source of
sacosine, glcine, serine, etc, modulates T and B cells and their products,
impacts immune modulation and oxidative processes.
Interferon: Good anecdotal reports of helpfulness and success in treatment of ill cats but
no reports of it actually clearing the virus under controlled conditions.
Blood transfusion: Help some cats.
Appetite stimulants: Diazepam, oxazepam and cyprobeptadine
Hill’s A/D diet.
Haemobartonellosis: Treatment for a blood parasite, sometimes a complicating factor in FeLV
It is responsive to doxycycline (10mg/kg of body weight once a day)
Doxycycline is of the Tetracycline family.
Alternative Care: Additional support is needed to reverse symptoms
Symptoms may reappear with disregard of supplementation protocol
Vitamins A, E, B-Complex and C plus the minerals Iron, Zinc, Copper
Pet-Tinic – liquid vitamin mineral supplement with Iron
Life Force super Antioxidants and Vital Charge– made by Infinity 2
Feline Leukemia virus Kit – Cell Restore (herbal-Atractylodes (alba), Cudrania, dioscorea, Momordica charantia, Paeonia, Sophora), Cell Enhancer (herbal-Coix, Cymbopogon, Garcinia, Sarcandrae, Sprouted Rice), Virus Fighter (herbal- Andrographis, Angelica Dong Quai, Astragalus, Lonicera Flower)
Transfer Factor-boosts the immune system to help defend the body from all kinds of disease, infection and intrusion. Contains over 40 valuable nutrients, including amino acids, probiotics, essential fatty acids and 25 vitamins and minerals considered essential for the optimal health of your cat. Also includes a synergistic blend of glucosamine and chondroitin, designed for felines. It is a lymphokine – the two most notable lymphokines are interferon and interleukins. The need to use antibiotics is lessened. Transfer Factor can stimulate a better immune response to respiratory bacteria, skin pathogens and various viruses.
