1Each of 8 cats in the control group received no treatment. Each of 8 cats in the 19.5% w/v indoxacarb group were administered the topical spot-on according to label directions on Day 0.
2 Each cat was infested with 50 adult Ctenocephalides felis from the KS1 strain on days -2, 7, 14, 21, 28, 35 & 42.
3Geometric mean # of eggs recovered from cats per treatment group.
4% efficacy = ((geometric mean # eggs control-geometric mean # eggs treatment)/geometric mean # eggs control) × 100.
a,b Geometric means across rows with unlike letter superscripts are significantly different (P < 0.001).
