Opened wet cat food: Is refrigeration a must or just a precaution?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Male | neutered | 7.4 lbs

Hi. My cat Miller is on Hills Thyroid Y/D. The wet food is a large tin and he only eats a half tin. I have always stored the other half tin, to be fed the next day, with an airtight lid and kept in the cupboard with no issue. I have recently read on the tin that the unused portion should be kept in the fridge. Is this just a precaution or a must? Thankyou. Leanne

If you keep the tin in the fridge then spoilage is slowed, ie the important nutritional ingredients will not change and the full nutritional value of the food will be retained. You should, however take the food out of the fridge and let it warm up or put it into the microwave for a few seconds, to get it to room temperature to avoid gastro-intestinal problems in your kitty,
