Review on 🐱 Pets4Luv Calming Collar for Cats - Pheromone Calm Collars for Anxiety Relief - Suitable for Small, Medium, and Large Cats - Upgraded Version - Adjustable, Waterproof, and 100% Natural - 2 Pack by Terry Looks

Don't let the price fool you, others are more expensive but this collar works and works fast! Our older cat was having trouble with the two new rescue cats we brought home and after a few hours he stopped hissing at them and was just sniffing. It was wonderful! When he's lying next to us, I find it reassuring. Lavender does it for me. I will also be ordering more for our new cat, she survived the cat throw/mass shooting so one of them is having trouble feeling safe. I hope this helps her too as she likes to hide below but still comes out for lovers.
