The Zymox Enzymatic Ear Solution with HC 0.5% is very effective for cleaning and treating ear infections in both cats and dogs. The Enzymatic Ear Solution provides treatment for fungal, bacterial and yeast infections, including staphylococcus, malassezia, proteus and pseudomonas. The solution reacts with the debris and pus in your pet's ear and kills all of the micro-organisms. Capable of being used daily, Zymox Enzymatic Ear Solution is a non-invasive product that does not require cleaning before and during usage. Enzymatic Ear Solution contains no antibiotics, so it is safe to use on antibiotic sensitive animals, rodents, even exotic and uncommon pets.
