Cats like consistency, so sometimes feeding her in a new place at a different time or in a new bowl may cause her to not eat. Occasionally a food may not be stored properly or might be too old and the fats have started to go rancid, which can lead to feed refusal. Sometimes when the weather is too hot your cat might not want to eat. Lastly, determine whether your pet may have had too many treats or may have gotten into the pantry or garbage and so may already have eaten her daily meal. Leading the list is chocolate.
Chocolate contains a substance called theobromine which is toxic.
Never feed chocolate or food containing chocolate to your pet. Also, never feed an onion to your pet, as large amounts can destroy your pet's red blood cells causing anemia. While many people give their pets raw meat, fish or poultry products these meats contain bacteria or possibly parasites, which are killed in the cooking process. For this reason, raw meats are also not recommended. Softer bones, such as those from pork or poultry, should not be fed, as they can splinter and puncture the intestines.
