They are both equally as good for controlling fleas. Some people prefer one versus the other, but as far as the evidence goes they both work well to kill fleas. Frontline has the advantage that it also kills ticks. The advantage II also has this capability though. You may consider getting them both and seeing if you see a difference form month to month. Treating for fleas is not just restricted to the host, because fleas can reproduce and nest in the environment and continually cause an issue. Below is a link to a short article that explains treating the cats and environment for fleas: https://www.petcoach.co/article/5-tips-to-get-rid-of-fleas/ I hope that helps and all is well with Luci.
