Review on Vet-Recommended ThunderWunders Cat Calming Chews - Effective for Reducing Situational Anxiety, Vet Visits, Travel, Separation, Fireworks, Thunderstorms & More! 100 Count by Russell Robertson

Bought for a hyperactive, nervous cat. At first I was ambivalent about it. The cat took it, liked it and worked. One caveat: Can only be given for seven days at a time, then it must be stopped for a certain amount of time before it can be resumed. Nowhere have I seen what is noted in the listing. Doesn't work if cat doesn't accept. It seemed to really calm our cat that night, but most importantly it didn't knock her out, just relaxed her. Highly recommended.
