Sometimes alley cats. Now they're referred to simply as ferals. Stylistic changes in the language over the years. I'm always a step or two behind. Actually cat groups, cat people or the cat industry have come up with official more technical definitions for each. I don't inquire I simply help when I can.
This is Charlie who I've blogged about before. Neighborhood tom who now allows me to pet him. Comes around fairly regular. All my cats are fixed so there's no shenanigans going on. Incidentally Google always corrects it to Tom like that's his name. Clean cat for a feral. I think the neighborhood people look after him. Dead rats and mice fairly regular sight around here. Cats doing their job. Unfixed toms have a big face. Mr, Galaxy calls it a face mask to help protect them during cat fights. Stay out of trouble Charlie.
Tip: Pulled chicken which you can get at many supermarkets these days share it with the cats.
