Im looking to find a cheap but healthy food for ferals. Im a senior citizen and on fixed income. I would like to feed a high protein, quality food that is cheap. Ive tried getting help from a few rescue groups but it seems as though you need to be in the loop to get help and if youre not, forget it. Ive been feeding TSC'S paws and claws brand but they're not doing as good as they were on it. I think they may ha2vr changed the formula. Any thoughts?
