Hi I have no experience with cats what so ever. This morning when I was hanging the washing out I noticed a whimpering sound investigated and found a cat under the bench, whimpering looks very thin, dragging it's legs barely moving oh god the thing looks awful :( no collar fur matted. It took a chunk out Of my hand when I tried to bring it indoors. I've put down water what do I do? Looks young I think. Don't want to leave it
