Zylkene is a well-researched calming supplement designed to help cats and dogs manage stress in a natural and gentle way. Using casein, a milk-derived protein known for its calming effects in newborns after breastfeeding, Zylkene delivers "calming messages" to the brain through your pet’s natural neurotransmitter system. This promotes relaxation without causing drowsiness—making it ideal for both short-term stress and everyday anxiety.
