One remedy for addressing mange calls for a 1 percent hydrogen peroxide and water solution mixed with borax powder. For every 2 cups of solution, add up to 2 tablespoons of borax and mix. Use this to bathe the affected cat once a week, allowing them to air dry afterwards.
Do not use this treatment longer than two months. Alternately, apply cooking oil directly to dry patches of skin to ease the irritation and moisturize. The oil also kills any mites that come into contact with it. Another method uses lemons. Cut one lemon into slices, leaving the peel intact, and add those to a few cups of boiling water. Allow the mixture to steep and cool overnight, and apply it to the animal with a sponge.
Remember that regularly brushing the cat's fur also helps remove dry and scabby skin and promotes healing. It is also important to keep the cat's bedding clean when treating for mange to prevent re-infection. While mange can often be safely treated with these remedies, it is important to consult with a veterinarian about any treatment. Because mange can also lead to dangerous secondary bacterial and fungal infections, it may ultimately require pharmaceutical treatment.
