2 reviews forRoyal Canin Expert Calm Cat

Both my cats love the food but I can't say I've noticed any difference in the stress and anxiety of the affected cat.

Can't fault product; cats liked it.1 of my rescue cats is v anxious.I tried usual behavioural things,pheromone sprays etc,then saw this so thought I'd try it. Its chemistry says it breaks food down to products which increase Serotonin (happyhormone). In humans sometimes has the opposite reaction - increased anxiety &agitation. This happened to my cat,after 2-3 weeks he was v distressed, meowing constantly.Stopped it &he slowly got back to how he was previously. Disclaimer - I am a psychiatrist
