Great product

I started giving this to my cat as he has Feline Ocular Herpes & required eye cream daily or every 2nd day. Now I add it to his wet food twice a day. He rarely needs the eye cream any longer which makes is both happy. It is palatable & easy to use. Since starting on this he has become more active/energised & the shoulder issue he has appears to have less impact on him. Very happy with this product

Paste Has Done an Amazing Job

I had long suspected my 16 year old cat had symptoms from an feline herpes infection as a kitten. This displayed in his case as chronic congestion, thick saliva and sneezing attacks. I finally discovered Enisyl-F for cats, and even after the first day he was vastly improved. Now, after a week or two, he is a new cat, and his quality of life has made a huge jump. The saliva problem seems to have gone, and sneezing is now minimal, and is of no concern. I had to wait a long time for this product as it seems to be in very short supply.

Works Wonders!

My kitten had all the signs and symptoms of cat flu but tests came back negative. The vet recommended using this product and ever since my kitten's symptoms all go away - no sneezing, no runny eyes and overall healthy & happy. I wish you could buy in bulk!

Great for Cat Flu

This really helps if your cat has cat flu as it boosts his immune system and helps him feel better. Less sneezing and he is much happier.


Easy to mix in the food and was recommended for my cats by my vet. My cats have the Herpes flu virus and I think their health has improved.
