TLDR A cat with ear infection and skin issues was successfully treated for Demodex mites using imidacloprid and moxidectin.

A rare case of feline demodicosis caused by Demodex cati was reported in an 11-year-old male mixed breed cat with a history of FIV and GSC, presenting with progressive cervical pruritus, alopecia, and otitis. Parasitological examination confirmed the presence of Demodex sp., with genetic sequencing showing 99.33% homology to D. cati. Treatment with imidacloprid and moxidectin in spot-on formulation, administered in two doses at 30-day intervals, successfully led to the remission of clinical signs and elimination of the mite.
