Middle-aged cat with skin wounds cured in 30 days

Patient history

Period of reference: October-December 2012

  • Stray cat adopted 3 months ago. History of gastrointestinal disease due to worm infestation (treated). The cat has previously been treated with injectable antibiotics for a rhinitis and conjunctivitis. Moxidectin plus imidacloprid spot-on was applied earlier, but this hadn’t been repeated because of the appearance of skin lesions on the trunk right after application. Pruritus was observed in the last 2 months, and skin ulcers on the dorsum were apparently non-responsive to one injection of an antibiotic (cefovecin). The cat was referred for a second opinion.
