The feline patient should receive one feline formula tablet two times per day‚ or as directed.

Sick cats can be especially finicky about foods and supplements; tablets offer versatility for this traditionally finicky species. The feline formulas can be administered in a variety of ways‚ including:

Whole tablet as a treat
Whole tablet mixed with food
Broken into large pieces and mixed with food
Crushed into a powder and mixed with food
Cautiously‚ as a powder suspended in water and given by oral syringe

In order to familiarize the patient with the supplement‚ it may be helpful to place one tablet beside the food bowl for 2-3 days prior to mixing it with their food.

Practice Notes
A full diagnostic work-up including a CBC with differential‚ chemistry profile‚ urinalysis‚ feline leukemia and feline immunodeficiency viral testing‚ and lesion-specific diagnostics should be considered for each patient.

Possible warning
January 22, 2014
I took my cat to a holistic vet who prescribed this product for my 4 year old male cat. Nearly two months after taking it he became deathly ill with extremely high liver values. We do not know if this product caused his illness but I just feel the need to warn people. Also, I regret that only after I had given this to my cat, I carefully read the ingredients. One of the ingredients, Eleutherococcus Senticosus (aka Siberian Ginseng), is something I was given several years ago and it raised my blood pressure and caused heart arrhythmia problems. Why it is in a formulation for cats is puzzling. As I said, this product may have had no impact on my cat. I am merely pointing out that caution needs to be taken especially since it is not FDA approved. I'm happy to read that some cats do well on this product. I certainly hope I did not cause my cat's illness by giving this to him.

I would recommend this item to a friend.

Worked like a miracle for my cat

My Bob-Tailed Manx male was getting sick and breaking out with blisters on his lips and inside of his mouth. He refused to eat for days and constantly drooled and his breath smelled of death. My vet recommened Feline Immune System, he will eat them from my hand, and he feels wonderful. NO MORE BREAK OUTS or SICKNESS. Cleared him up in about 24hrs. Very good product!

Works for my cat
April 4, 2012
My cat has chronic rhinitis and probably immune suppression following years of steroid therapy for a stomach condition. My vet recommended Feline Immune System Support by Standard Process , and it does make a difference. It seems to keep the rhinitis under control; without it, he gets stuffy again. It's unfortunate that he doesn't like the tablets enough to eat them, but I'm able to pill him with them instead.

Excellent product !
February 26, 2011
Started using this on the recommendation of a holistic vet who was treating one of our cats that was suffering from recurrent, high fevers. Cat had no other symptoms, tested negative on numerous occasions for leukemia and other kitty illnesses. Since starting on this product, no more fevers ! Have also used it for a number of rescue kitties and always get great results. One of those products we won't be without for our feline companions !
Great results and cats like the tablets.
