Query: Didn't help at all

I got this in preparation for a long distance move I was going to be making with 3 cats. My cats were going to have to spend 12 hrs in a car and I wanted to make it as easy on them as possible. I ordered this a few weeks in advance and tested it out on the cat that I knew was going to have the most issues with the car ride. He also tends to get very hyper at night and drives the other two cats nuts, so I gave this to him in the evenings, hoping it would help calm him down. The dropper made it easy to give to my cat and he didn't seem to object too much to the taste, but it made no difference in my cat's behavior. I tried it multiple times and also tested it on one of my other cats. It never made a difference for either of them and I ended up throwing it away.
