Every cat owner recognizes the warning signs of an upset feline stomach: the mournful meow, gagging and the heaving retch. But just as suddenly as it began, your cat returns to good health while you’re left scrubbing the carpet.
The scenario is a familiar one for Cynthia Bowen of Cleveland, Ohio. As the owner of four Maine Coons, Bowen has cleaned her share of messes. “It would happen every couple of months or so,' she says. 'Otherwise, they were perfectly healthy.'
Although it's not a pleasant subject, vomiting is something cats seem to do on cue. Many cat owners accept this as a natural part of owning a pet, but it doesn’t have to be that way. Knowing what triggers an upset stomach and what you can do about it will make for a better relationship with your cat.
Many owners attribute their cat’s vomiting to hairballs, but that’s not the only culprit. “It’s careless to assume that most cases of vomiting in cats are due to hairballs,” says Dr. William Folger, a DVM from Houston. Two other frequent causes of an upset stomach are eating too fast and curiosity.
Cats sometimes eat too much too fast. When the stomach wall expands too quickly, a signal is sent to the brain to cause regurgitation. In these cases, the mess on your floor is from regurgitation, not actual vomiting. When a cat regurgitates, she brings up fluid and food from her esophagus by opening her mouth — unlike vomiting, which involves gagging and retching.
Regurgitated food is still formed and may smell fermented. “Cats that eat too quickly because they are gluttonous or stressed by food-bowl competition can regurgitate right after eating,” says Dr. Sara Stephens, a DVM from Montana. But don’t assume regurgitation is always a case of eating too quickly. It could be caused by esophageal problems, obstruction of the digestive tract, hairballs or dehydration. If you’ve forced your cat to eat slowly and she still has problems, contact a veterinarian.

Grass, carpet and toilet paper are just a few things cats may digest and later vomit. The vomiting is a protective mechanism — nature’s way of cleansing your cat’s system. Sometimes, though, curiosity can lead to more serious problems. String, toy parts and feathers are favorites of playful felines and can lodge in the stomach or intestine, causing repeated vomiting and severe distress. If your cat exhibits these symptoms, take her to a veterinarian immediately. Surgery is often necessary to remove the object.
Repeated cat vomiting should never be ignored because it can lead to dehydration. But because vomiting is common in cats, how do you know what’s normal? “A general guideline is that if the cat is vomiting one to three times a month, we consider this normal,” says Dr. Folger.
He considers it serious if the vomiting occurs twice daily for two or three days. If your cat stops eating, seems to have stomach pain or retches continuously, or if the vomit is mixed with blood, take her to a veterinarian. And as always, if you’re suspicious that a lingering problem could be harmful to your pet, call your veterinarian. A visit to the office can help relieve your cat’s discomfort and your worries as well.
Often, owners accept their pet’s vomiting as a natural part of their behavior, but just because cats seem to have more than their fair share of stomach issues doesn’t mean you don’t have options.

One simple preventative measure is to get your fast-eating cat to slow down or to simply eat less. Dr. Stephens recommends feeding smaller portions, elevating your cat’s food dish slightly or putting an object, such as a ball, into the dish. The cat will be forced to eat around the ball, thus slowing her intake. If you do this, make sure the ball isn’t small enough to swallow. And you may need to feed cats in a multiple-cat household at different times and places to reduce competitive eating.
If simple solutions don’t work, watch your cat’s eating behavior and reactions. Bowen, for example, tried changing her cats’ diets. “Since switching to IAMS™, they rarely throw up,” Bowen says.
“Usually, when you change to a higher-quality diet, there is no problem,” Stephens says. Here are some tips for helping make sure your cat’s food transition is as successful and comfortable as possible:
If your cat vomits more than three times a month or has chronic stomach issues, you can take several steps to help resolve her discomfort. With your veterinarian’s help and a little effort on your part, your cat’s stomach issues can be a thing of the past.
Why move your nearly grown kitten to a premium adult cat food? Because quality counts. It's crucial to continue the superb nutrition she's been getting from a premium kitten food into adulthood. Downgrading to a basic nutrition brand at this stage of her life may upset her digestive system and certainly won't provide her with the same type of nutrition she was raised on.
Think of a baby. When it's time to start giving him solid food, you wouldn't feed your child anything less than the best nutrition you can buy. The same is true for your maturing kitten. She needs the best age-appropriate food there is to help maintain overall health. Premium foods such as IAMS are formulated to meet all her needs and provide additional benefits. They're specifically designed to provide your cat with a formula that features:
High-quality ingredients
Balanced, optimal levels of protein, fat, moderately fermentable fiber, carbohydrates, vitamins, and minerals, which make costly supplements unnecessary
High-quality recipes and great taste
Standards that meet or exceed Association of American Feed Control Officials standards
Nutrient-dense formulas that are right for each life stage
Product guarantees
What do all of these features add up to? A happy, healthy cat. With premium cat food, you can expect to see these important indicators of good health. They contribute to providing your cat with a long, healthy life:
Exceptional muscle tone
A shiny, luxurious coat
Healthy skin and bones
Clear, bright eyes and clean teeth
Small, firm stools
Founded upon decades of research, premium formulas from IAMS help maintain your cat's health and help provide him with the nutrition he needs for a long life. Generic brands simply may not match the level of expertise that goes into every bag of IAMS cat food.
When your cat is about 12 months of age, it's time to change her diet to a premium maintenance formula. When you transition your cat to an adult diet, it's important to monitor her weight and body condition and adjust portions if necessary.
Because cats generally eat only what they need, free-choice feeding is adequate for most cats. (Free-choice makes food available to your cat around the clock and lets her eat when and how much she needs.) Indoor cats that don't get much exercise, however, may overeat if fed free-choice. For them, portion-controlled feeding twice a day is a better routine.
To determine how much food to give your cat, check the recommendations of the pet food manufacturer on the label. Use the guidelines and weigh your cat on a weekly basis. If your cat is gaining or losing weight and shouldn't be, slightly adjust her daily intake and weigh her again the following week.
To avoid intestinal upsets, make the change from a kitten formula to an adult diet over a period of four days with the following method:
Day One: Fill your cat's dish with 75% kitten food and 25% adult food.
Day Two: Mix adult and kitten food in a 50/50 ratio.
Day Three: Feed your cat a mixture that's 75% adult food and 25% kitten food.
Day Four: Switch to 100% adult formula.
