Review on 🐱 Adjustable Calming Collar for Cats - Relieve Anxiety and Reduce Stress with Natural Pheromones - Fits Neck Sizes up to 15 Inches by Karen Parker

I have a terrible reaction to most essential oils (Asthma and MCS). For some reason I couldn't find an ingredient list for it, but the description says lavender and chamomile. I took a chance and ordered it. The ingredients listed on the box (which I looked at foolishly after unbuttoning my collar) say lavender and citronella! This explains why my eyes started burning immediately and why I now have migraines. Luckily we have a few aggressive cats that only live outdoors and can be beneficial. I'll let you know what my daughter says about the effects on her. EDIT: We tried this on a street cat who seemed calmer but vomited and was lethargic within an hour. Collars are back. (the kitten is back to normal as we removed it immediately).
