Question: do you have to refrigerate leftover cat food?
Answer: Your pet's bowl should be emptied of moist or canned food not eaten by your cat or dog within 4 hours if the ambient temperature is above 50°F. Opened cans should be stored in the fridge, at temperatures between 40-45°F, for a maximum of 5-7 days. Any cat or dog food remaining after that time should be thrown out.
