My cat enjoys the taste if this product


good service very straight forward


Only been using the paste for a few days but it does seem to have helped our cat, still sneezing but not so much and discharge has also lessened. Her appetite has also increased :-)


Excellent.... fixed our cats weeping eye


it seems to work cat's herpes under control - so far anyway.


My cat had this on her food twice a day and didñt even know. She was diagnosed as having cat herpes and had a few lityle lumps in her mouth which have now disappeared thanks to the paste.


Great product only been using it 7 days and seems to be working on my cat


Competitive price + good service
