I am the proud, and no longer frustrated, owner of a 4 yr old "Tuxedo" kitty named JJ. JJ is a very needy kitty, always wanting attention and would provoke me by scratching, biting, and sometimes lunging at me with claws and teeth. Even after an hour of focused playtime, JJ would continue to lash out at me for attention. I was against putting him on a pharmaceutical like Prozac and a dog trainer suggested I try L-Theanine. After much internet research I found that Anxitane offered one of the most concentrated doses of L-Theanine on the market and provided the most bang for the buck (and VetDepot has the best price!). The recommended dose wasn't quite enough to meet JJ's needs so he gets one full pill in the morning and another before bedtime. He's the same old JJ with all the personality traits we love, but he's no longer hyper anxious and the lunging and attacks have decreased significantly. Anxitane changed both our lives and made my house a much more peaceful place. If JJ had his say, I think he'd recommend them too -- he loves taking them and because they are chewable they are really easy to dose. Highly recommended!
