We got a new cat. The first week he drove us mad with crying and howling and running around destroying things. We got this and did notice a difference. A lot calmer.

I forgot to repurchase and accidently let it run out. I could definitely tell the difference. He was back to his old tricks and that’s when I checked the pet remedy and realised it had run out.
Since then we’ve got it refilled and he’s a lovely cat again.
