I am wondering if wet gangrene in a cat's mouth could be contagious to humans? Specifically, my cat that I just had to put down had a mouth wound for some time and has been on antibiotics, but still had foul smelling drool/pus coming from his mouth. Then his tongue started turning black this past week and the Vet said gangrene had developed. The cat would shake his head at times while I was trying to feed him and I know this mucus may have gotten in my eye or lip or a scratch on my hand more than once. I heard that wet gangrene was caused by bacterial infection in the tissue. Should I be concerned? My other cat, who shares a litter box and water, has shown no signs of contracting anything from him these past 3 months.
