Cat owners sometimes blame a new cat food when their cat immediately throws it back up after eating. The connection seems logical, but other factors could point to a different cause rooted in behavior.
Regurgitation
Regurgitation, or expelling swallowed food through the mouth, can occur if your cat really loves a new food or competes with other pets in your home at mealtime.Here’s what happens: a cat eats so fast that she swallows food without chewing and ingests a lot of air, too. Large pieces of food and air in the stomach will likely come back up. If your cat throws up a whole kibble shortly after eating, regurgitation is likely to blame.
