I second the honey. I was prescribed "sterile honey" (yes, it's edible honey) for my wounds / scar tissue after an abdominal surgery for healing and preventing infection. Most animals just lick it off but it does work.Our vet always recommends honey, too. Last time this cat jumped off the roof and got a slice on her foot, he dipped her paw in honey and wrapped her up and she was good as new in record time.
