Made my cat instantly vomit!
Was so excited to try this with my 21 year old cat who is getting very stiff. However, he must be allergic to something in the product (green-lipped mussel maybe?) as yesterday morning and evening he vomited up so much food (undigested) after I had sprinkled it on his meal. So disappointing and as another review states, there is no leaflet inside the box regarding the product.
