Simba's ear still has not healed from his biopsy surgery over a month ago. I realize the ear is a sensitive area, but shouldn't it be healed by now? It drys up and scabs over, then once the scab falls off it is back to raw tissue again and the cycle repeats. Poor little guy has been wearing an E-Collar for a month. My vet doesn't seem concerned. It's just a very small area at the slit of the ear, but I keep thinking it should be healed up by now.
