3 Pack Adjustable Cat Calming Collar

I usually do not write reviews for products mostly out of being lazy. I was hesitant to purchase these because I didn't think they'd work. However, I was pleasantly surprised by the fact that not only do they work but they work quickly. My 2-year-old tuxedo was having really bad separation anxiety and started to overly lick herself to compensate. It has been working for the last few days to the point where I haven't seen her overly lick herself. She seems calmer and seems like she can relax more easily. I am very pleased with this purchase. I wish they didn't have a smell but beggars can't be choosers--especially if it stops you from having to put your cat on Prozac.
