Hey, everyone! I have a 4 year old cat that continues to lick a spot under his neck, to the point where it is very irritated and raw. It's probably about a 1-2 inch circle which he now has no fur. He had been licking on his back right at the top of his tail but hasn't done that for a while, just his neck. He is otherwise in good health and has been eating and drinking as normal. His skin on the rest of his body doesn't seem to be dry to irritated. What could be causing him to lick? What can I do to help it heal?
