->'''Sharon''': Sandwich?
->'''Tracey''': What's in 'em?
->'''Sharon''': Tuna.
->'''Tracey''': I didn't know we had any tuna.
->'''Sharon''': There's a tin started in the fridge.
->'''Tracey''': That's not tuna, that's luxury cat food!
-->-- ''Series/BirdsOfAFeather'', "[[Recap/BirdsOfAFeatherS7E3Cheers Cheers]]"

AliceAndBob are at a party and Bob starts to get a little hungry. So when he sees some food on a tray he helps himself to it. Cue Alice coming over and telling Bob he just ate the pet's food. Bob, being informed that unbeknownst to him that he was eating pet food, is either disgusted and spits the stuff out or [[ShrugTake shrugs]] and keeps eating the food.

Character in settings on the WrongSideOfTheTracks, or post-apocalyptic settings intentionally eating cans of pet food do not count as this trope, as the people know they are eating pet food.

In RealLife, pet food can be made with a lower grade of meat than is permitted for human consumption, which means that a wider range of meat and meat byproducts can be added. However, the most luxurious brands boast that they are made with human-grade products, so a mixup in the fridge could occur.

Similar to YoureDrinkingBreastMilk and sub-trope to IAteWhat. This is the unintentional version of DogFoodDiet. It might be caused because of the fancy-looking pet food packages, as GourmetPetFood is customary.
