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.
What to do
If you suspect your cat is eating too fast and regurgitating, take these steps to reduce the risk.
Transitioning
Transitioning to a new cat food too quickly can also cause your cat to throw up. Mix increasing amounts of the new food with decreasing amounts of the old food over a seven-day period to avoid discomfort.
If your cat is showing signs of discomfort after eating or vomits intensely or constantly, see your veterinarian immediately. It’s always a good idea to consult your vet before changing cat foods.
