My cat Pimousse had been showing symptoms of agitation and anxiety episodically for some time. I no longer recognized her, she started meowing loudly, for no reason, which is not her habit. She also followed me around the apartment, whereas she is usually a quiet and calm pussy. Subsequently, these "crises" became almost daily. Concerned, I finally talked to her vets who recommended a treatment with Miloa's Zen Supp ^TM. She takes half a tablet a day and I can tell you that the treatment was effective very quickly. The symptoms almost disappeared in 24 - 48 hours.
