Review on 🐾 Vetoquinol Zylkene Behavior Support Capsules for Dogs & Cats, 75mg - Natural Calming Milk Protein Supplement - Aid Pets in Coping with Change & Noise-Related Stress - Non-Drowsy Formula - Lactose-Free by Brenda Garvin

One of our cats has been taking this product for two months. In the first month the hair regrowth was nothing short of amazing. This batch was purchased from my vet. In the second month we not only observe a slowdown in hair growth, but also some regression: hair loss on both the hind legs and the front legs. This second batch was from Revain. While I liked the convenience of shopping at Revain, I don't want to compromise on quality or effectiveness. I called the manufacturer and after a lot of research she found out that this is a legitimate product but maybe an older batch but for some reason it doesn't work for my pet. I will continue to buy it from my vet.
