For the support of a cat's immune system against recurrences and symptoms of Rhinotracheitis. I've found this PARTICULARLY helpful in the resolution of "dendritic ulcers" on the corneas of the sufferers.

Science has proven that it doesn't work. At all. And the young vets are proud to say so, having never tried it.
For all I know, it's the fat in the formulation or some stupid vitamin but I know that my clients with Rhino-cats who are always getting ulcers or snuffles - find it runs these symptoms off pretty quickly where at one time they were intractable without Interferon or Acyclovir ancestor-drugs.
