Review on Lopnord Calming Collar for Cats: Reduce Anxiety, Lasting Natural Calm - Pack of 3 by Melissa Brown

UPDATED -- Took my girl to the vet and got these. I wanted to return it / I'm glad I didn't. My vet partially opened the jar and didn't believe it. They're cat poison - and pheromones we're not supposed to feel, and lavender is useless, and anything overwhelming. My child had to sleep. From sitting pretty for treats to being lethargic, barely able to walk. and now she's gone. I collared her for 24 hours - because she sleeps in her bed - and almost immediately removed the collar from my other who sleeps in my bed! I got hives and my son and I started congesting the sinuses and throat. I am sorry from the bottom of my heart for leaving this on my calico - today we have an emergency visit to the vet. And I fear the worst. She doesn't eat - she's sick of the water she drinks - and doesn't want to move and looks in pain when she staggers a little. It used to be ok, I bought it because the new charts I was reading made her anxious and thought I was taking the initiative. Do not do that.
