Cats are not usually struck by bacterial skin diseases unless they have some underlying health disorder that lowers their skin defenses. If left untreated, they can spread to the deepest layers, making the condition more serious and treatment more difficult. Signs of bacterial skin infection may include reddened skin, pimples, blisters, and dry, crusty patches. Your cat's skin might be weeping, and you may notice flakiness. Mild to severe scratching and spots of hair loss may also be seen. Your veterinarian may prescrive oral antibiotics, immune stimulants, and nutritional supplements. To promote healing, skin lesions must be kept clean and dry. Daily administration of antibiotic ointment and baths weekly baths with medicated shampoos may promote healing.
If you would like to treat a bacterial skin infection at home before going to the vet, or you are unable to go to the vet right away, you can apply soothing, antibacterial sprays to the most inflamed areas several times a day. Add vitamins C and E as well as zinc and sulfur to your cat's diet. Proteolytic plant enzyme dietary supplements strengthen the immune system and are very helpful. If an allergy is the underlying cause of the bacterial skin disease, you also should switch your cat's diet to a high-quality, hypoallergenic one. Carefully monitoring your cat's health and maintaining it with proper nutrition will result in a strong immune system that will resist bacterial invasions.
