Cat Leaving the Bowl Half Full? Science Says There's a Surprising Reason

If your cat has been leaving food in their bowl lately, you're probably wondering what's going on, and a new study may finally have the answer. And according to research covered by Smithsonian Magazine, the explanation might be simpler than you think.

It turns out that just like us, domestic cats can get bored with eating the same meal day after day. A study published in the journal Physiology & Behavior ran several feeding experiments examining how cats eat, and the results were consistent; our feline friends get tired of walking up to their bowl and smelling the same food on repeat. This makes them far less interested in eating what's in front of them, and honestly, who can blame them?

While it can be frustrating to cat parents, according to Smithsonian Magazine, the fix is surprisingly simple: just change up the scents around your cat's food.

The Simple Trick That Gets Finicky Cats to Eat Every Last Bite

One of the study's co-authors, Masao Miyazaki, an animal behavior researcher at Iwate University in Japan, says in a statement, "Findings suggest that cats do not stop eating simply because they are full. Rather, their feeding motivation decreases as they become accustomed to the smell of the food, and it can be restored by introducing a new odor. Sensory novelty, especially olfactory novelty, can reactivate feeding motivation in cats."

If your cat gets the same wet or dry food every day and regularly leaves some behind, it may be time to mix things up. Try picking up two different kinds of dry food and simply rotating between them every other day.

Wet food is often available in variety packs, which makes rotation even easier. Just serve a different flavor each day to keep your cat coming back for more.

Another simple solution is adding a topper to your cat's food. Stella & Chewy's explains that toppers like their freeze-dried raw Marie's Magical Dinner Dust can make mealtime interesting again. They also recommend a few other easy fixes, like adding a liquid or broth to the food, rotating through different bowls, and switching up feeding locations. And if you haven't tried it yet, a small sprinkle of catnip on or around the bowl may help too, since catnip can act as a natural appetite stimulant for some cats.
