  1. 1In the fluralaner group cats were treated once topically on day 0 (Bravecto® Topical solution; Merck Animal Health, Madison, NJ, USA)
  2. 2In the selamectin group cats were treated on day 0 and once between days 28–30 and 56–60 (Revolution®; Zoetis, Whippany, NJ, USA)

  5. a,bArithmetic mean SCORFAD lesion scores in a column with like letter superscripts are not significantly different (P > 0.058; │t│ ≥ 0.21).
  6. x,yArithmetic mean SCORFAD lesion scores in a row with unlike letter superscripts are significantly different from day 0 (P < 0.001; │t│≥ 3.35; day 30 Selamectin vs baseline P = 0.13; t = 1.53)
