So Pepper is on medication for his diarrhea (which I can say is working well), and he acted like a 5 year old when I first tried to give it to him(now he is great about it and allows me to keeps the syringe in his mouth without chewing it) some meds accidentally dribbled down his chin. I cleaned up most of it, but the bottom of his chin is still spiky+matted. He keeps rubbing it as well. Also, his nose is a bit redder(probably from all of the rubbing). How do I clean the matted fur?
