Bests & Worsts Reviews from Amazon

The cat was enthusiastic about the first one out of the bag.. for an hour. The smell was strong when you first open the bag. But kitty quickly lost interest in the first one, and when I reopened the bag a few days later to try a fresh one, he couldn't care less. The scent was gone, even though I'd resealed the bag right away. I wondered if these were sprayed with a scent and not natural silvervine, but this was my first silvervine purchase, so I don't know.
