He probably would not eat it, cause they smell their food and if they don't like it they won't eat it. If he were to eat it, he would probably throw up later.
Hello. I don't think that cat will eat bad food, these animals are not stupid:) They definitely know what will be better to eat. I don't think that you should give moldy products to your pet. I recommend to buy something from ABOUND has both kibbles and canned recipes, this brand provide really good quality.
