I never write reviews but this works and has helped me so much. My adult ragdoll cat was not taking at all to the new kitten I bought home. She would hiss, spit, attack and refuse to come downstairs. I was so scared I lost my baby girl. However, within minutes of spraying, wiping the laminate floor with wipes and plugging in the diffuser she came down and is now interacting with myself and the kitten. Still a few hisses here and there (can’t work miracles after all) but it has helped her feel more at ease. I actually can’t get over how instantly she reacted!
