## Bottom Line

Based on reviews, the Feliway MultiCat Diffuser Refill can often promote calmness and reduce tension among cats, but safety concerns around overheating are a major downside. We recommend carefully monitoring the device if you decide to try it, especially given the heating and safety risks. If safety or reliability are priorities, you might want to explore other calming options or diffusers designed with better heat management.
