Bottom Line
The FELIWAY MultiCat diffuser refill is a popular choice for helping reduce cat aggression, especially in multi-cat households. According to reviews, it often works well to calm anxious or aggressive cats and promote household peace, but its effectiveness is not guaranteed, and some users see limited or no changes. If you're seeking a dependable, long-term solution, you might want to explore other options or consider combining this with other behavioral strategies.
