Katherine King –
My cat became much calmer during thunderstorms after using the Sentry collar. It’s easy to put on and the pheromone effect lasted the full 30 days. No side effects noticed.
John Welch –
Works well during fireworks. My cat didn’t hide or meow as much. The breakaway feature is a relief if she tries to pull away.
Adrian Rampling –
Fits my 12-inch cat perfectly. After a few days, she seemed more relaxed during car rides. The collar is comfortable and doesn’t irritate her skin.
