Review on Value Pack of Comfort Zone Multi-Cat Diffuser Refills: Stop Cat Fighting, Reduce Spraying & More for a Peaceful Home - Veterinarian Recommended by Laura Jones

My cat started marking my couch and my dog's bed a few months ago and has been getting a little aggressive towards his sister so I ordered these pheromones , To help. He's definitely cooled down a lot and gone back to his normal self! I think the new 2X formula makes a huge difference - I tried the old formula about a year ago and it only helped marginally. This formula works much better. The product advertises that it lasts up to 30 days and at least using it with an old style diffuser is definitely not true - and that's what you'll find in other reviews. I had my first gas station on the grid for 19 days and it now needs to be replaced. I'm going to buy a new type of diffuser and see if that affects durability. I would definitely recommend this product to help your cat calm down but be aware that the bottle may not last as long as advertised.
