One of my cats was rattlesnake bit last summer. Gave her industrial strength oral antibiotics and a penicillin injection.
By the time the necrotic tissue fell away, she had a hole 5” across and 3/4” deep. I dressed it with manuka honey. Within 48 hours all new very clean and healthy tissue was rebuilt. My vet and I were shocked.
Only the skin had to be pulled together. It took 22 staples and the vet said that it was the cleanest wound she had ever seen.
You are a hero. Thanks for sharing.
