Efficient
Cat with OCD (walking in circle like a lion in a cage) following a difficult living situation ( I thought it might be something worse): after less than a week (mixed with its wet food), my cat ois more serene and its OCD calme down. I think i saved myself some really expensive vet fees because seeing how well he is with zylkene, he obviously only suffers from anxiety. I am so relieved and so is he.
