The human nose is well developed to detect spoiled food, so if the food smells fresh you can safely give it to your cat.
Your catscat's nose is a lot better than the human nose, so if your cat eateats the food you can trust the food to be good,A. A cat trusts only itself when it comes to what to eat, so if the food is spoiled your cat will not eat it (unless the cat is realyreally starving).
