Our 15yr old tabby Maine coon lad has had a nasty sore on the back of his neck for months. I have had the vet look and treat probably 4 or 5 times. The vet reckons the injury stems from a cat disagreement which festered and became infected. The wound started as about the size of a raisin, now it is about a 2p piece size, and not healing. If he manages to leave it alone long enough it scabs up, a black crumbly matter, which breaks away in small bits. Eventually it will become dislodged completely with him itching despite fuciderm being applied and shots for anti biotics. Now it once again red raw, and I feel terrible not being able to sort it out for him. The vet gave me fuciderm to put on daily, but it isn't healing. A collar is out of the question according to the vet as it will likely rub the area, and besides ziggy would freak out with that on him. The latest from the vet is we might take him into surgery to clean all the dead tissues and give the area the best chance of healing. I have doubts though. Does anyone have any similar experience of this, or any ideas on how to proceed. Poor ziggy, he seems ok otherwise but something has to be done.
