canned food for ferals

My wife and I feed a small army of ferals in our backyard; usually, we just give them dry food (Friskies, Purina One, etc.),but we also give them canned food, also Friskies, but they just seem to like the gravy portion of that. Is there a feline "gravy" available, similar to the IAMS Savory Sauce(s) for dogs ?

Thanks,
Shell

There is an Iams Savory Sauce for cats, but I've tried it and my cats wouldn't touch it!

Most people I know who feed ferals put mashed canned food over the dry food. They get large cans of Friskies inexpensively at PETsMART or Petco and it works pretty well. One big can works for about 10 cats.
