 ^{1}Each 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 spoton 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.
 ^{3}Geometric mean # of eggs recovered from cats per treatment group.
 ^{4}% efficacy = ((geometric mean # eggs controlgeometric mean # eggs treatment)/geometric mean # eggs control) × 100.
 ^{a,b} Geometric means across rows with unlike letter superscripts are significantly different (P < 0.001).
