@wonderwop You are a good man, and now you own a cat. Years ago there was a black Tom cat that adopted us we named him big head, he would get into fights and his head had an infection, he would not let us touch him so my husband trapped him and took him to the vet, they gave us antibiotics to put in his food and he got better. We fed him for several years and one day he did not come back, never knew what happened to him.
