My Experience With Feliway Optimum

When I first plugged in Feliway Optimum, I was dealing with a mix of issues.
One of my cats had started hiding more after a home renovation, another was scratching furniture excessively, and there were occasional tense stares between them.
I placed the diffuser in the living room, where everyone hangs out most.
Within about a week, I noticed my shy cat venturing out more often. The scratching reduced noticeably, and the overall vibe in the house felt calmer.
Even the subtle jealousy over attention seemed less intense. I could tell when the refill was running low because the hiding and minor tensions crept back.
Feliway Optimum felt like it created a blanket of security. It addressed not just cat-to-cat stuff but also individual stresses from changes or noises.
In my multi-cat setup, it helped everyone feel more at ease together. I appreciated how versatile it was—great for everyday serenity.
Switching from MultiCat to Optimum gave me faster results in some areas, like reduced hiding. Some days, the house felt noticeably more peaceful. It’s become my go-to when I want comprehensive calming.
