You must understand that once you start giving this stuff to your cat, you will never be allowed to stop. I think it might even say that in the fine print somewhere. Just so you know.
Goodness people - I'm serious, once you start with this as a treat you've got a fiending cat underfoot every time you go to the fridge. Ha, I even found some testimonials on the catsip site! Oh and you can also find out there what stores in your area have it. Good luck!
