Pros: Calmed cat slightly
Cons: Way too much $$ for slightly working
Now, I will say I only tried this twice, after which I decided it wasn't worth the time to use it. I had to give my cat subqs and let me just say, he didn't like it. That's a massive understatement, by the way.
I was desperate. I had a very sick cat that *absolutely needed* these subqs. I tried this spray, followed the directions. He struggled just slightly less, but he was still clearly agitated. Tried it again the next day, same thing. Just not worth the time and definitely not worth the amount it cost. Especially since I don't know for sure if that was the reason, or he was just getting used to it.
I will try it again if needed, perhaps it will work better with a different cat. Giving 2.5 stars because it did have potential.
