The Control (CP) group was treated topically once on Day 0 with 0.12 mL/kg Technical oil.

2

The Treated (IVP) group was treated topically once on Day 0 with 0.12 mL/kg of the novel formulation of (S)afoxolaner, eprinomectin and praziquantel.

3

Percent efficacy = [(C − T)/C] × 100, where T and C are arithmetic means (AM) of the IVP group and the CP group, respectively.

4

p-value = two-sided p-value from the MIXED model of the IVP group and the CP group.

5

n = number of cats per group: one cat was removed on Day 50 because deemed unsuitable to remain in the study for excessive tick bite wounds, consequently n = 9 in the control group on Days 55 and 60.
