Cats are such picky eaters because they are naturally driven to eat foods with a preferred ratio of protein to fat: 1 to 0.4, according to a study.
When Fluffy turns her nose up at the bowl of food you've placed in front of her, don't take it personally. Your seemingly high-maintenance cat has evolution to blame for her picky eating.
Aroma, taste, and texture of food are less important to cats than is nutrition, according to a new study that helps explain not only finicky feline behavior but also what primarily controls cat cravings.
Cats as it turns out are driven to eat foods with a preferred ratio of protein to fat: 1 to .4. This translates to about 50:50 in terms of the percentage of energy from protein and fat, according to the authors of the study, published in the journal Royal Society Open Science.
