My beautiful rescue Maine Coon cross had been badly treated before I found her. After 3 years of love and patience, she's fine with me, but still disappears as soon as anyone visits. She's terrified of fireworks and practically any loudish noise. Zylkene was recommended by the vet, and I use them before and during noisy times, along with a Feliway plug-in at all times. It's a natural, gentle treatment for anxiety, and it works, without any drowsiness at all.
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.
