Cat Food for Older Cats That Vomit – Buyer’s Guide

As your cat ages, it’s normal to expect some vomiting. Increased hairballs, food sensitivities, and eating too quickly can bring on a vomiting spell. Yet, vomiting can also be a symptom that something else is going on with your cats like diabetes or organ failure. And this is why it’s important to bring any concerns up to your veterinarian.

Food sensitivities are a big cause of vomiting in older cats. Their system is less able to handle some of the ingredients in their foods. As a result, they get sick soon after they eat. Changing your cat’s food to one specially formulated for older cats with vomiting issues can help.

Common Changes with Older Cats

You do want to take your cat to the veterinarian if they continually vomit because the vet can pinpoint exactly what the issue is. However, there are a few body changes that happen as your cat ages that can trigger vomiting. These body changes include:

  • Slower Metabolism – Your cat’s activity levels and their metabolism slows down as they age. This makes your cat prone to weight gain, and this can lead to other problems that cause them to vomit.
  • Unable to Break Down Food – An older cat’s digestive system becomes less able to break down the food they eat and extract the fats and other nutrients. This makes them feel more hungry, and they eat faster. Eating too quickly and trigger digestive upset.
  • Meat or Grain Sensitivities – Some meats or grains can trigger inflammation in your cat’s digestive tract. If your cat’s food has these ingredients, they can get uncomfortable or sick after they eat as their bodies try to dispel whatever is making them sick.

What Causes Cats to Vomit or Throw Up

There are several reasons why a cat may throw up or vomit after they eat. Your vet will be able to tell you what they think the most likely cause is. A few very common reasons include but are not limited to:


Your cat licks their fur to clean themselves, but this can cause them to ingest a lot of hair. This hair can cause the hair to build up in their digestive tract and upset their stomach. As a result, your cat will throw up quite a bit, especially if they keep ingesting hair.

Urinary Tract Infection

Any infection in your cat’s body can upset their digestive system. Additionally, urinary tract infections are very common in older cats. If your cat has an ongoing or chronic issue, you can find them throwing up more. As the infection gets worse, so can the vomiting.

Ate Something Inedible

Think of everything you have laying around your floor. Pieces of string, plastic, bottle caps, fibers, and more are all things your cat may pick up and eat. When these inedible things get in your cat’s stomach, the body can start to try and dispel it. If this happens, your cat may experience runny stool or vomiting. The object can take between 10 and 24 hours to pass.


Another possible reason your cat is throwing up is diabetes. Diabetes is common in older cats that are overweight. Diabetes can cause excessive thirst. And this means your older cat will drink much quicker over shorter periods. This quick influx of water can lead to vomiting.

Buying Criteria for Food for Older Cats That Vomit

We’ll outline several different things you want to keep in mind if you have an older cat that is struggling with vomiting. You want your cat’s food to have as many of these things as possible to ensure they’re getting everything they need to thrive.

Protein Source

Your cat’s food should have a protein that comes from a real meat source. Whole meats are preferred because they’re healthier for your cat. Whole meats are easier for your cat’s digestive system to break down after they eat it. Meat meals or meat by-products are more difficult, and they can cause your cat to feel sick.

Whole Grains

Just like the meat source, the grains in your cat’s food should be whole grains. Whole grains are more nutritionally sound than grain meals. You may find things like brown or white rice, soy, wheat, or corn. Ideally, the food will contain rice because it’s easy for your cat’s digestive system to break down.


If your cat has digestive issues, fiber is key to helping regulate their digestive system. Fiber works to help the body push the food they eat through their digestive tract. It can prevent upset and constipation while giving your cat’s body enough time to extract the vital nutrients it needs from the food.


Antioxidants help support your senior cat’s immune system by repairing any cellular damage that might be there. Green, leafy vegetables, and fruits like blueberries are excellent sources of antioxidants. Some food also has small pieces specially formulated with higher levels of antioxidants in them.

Things to Avoid in Your Cat’s Food

Along with the good, cat food can have ingredients that aren’t so good for your cat to eat. This is especially true if your cat already has sensitivities or digestive issues that cause them to throw up. These ingredients include but are not limited to:

  • Overly processed foods
  • Feed-grade grains
  • Artificial colors, flavors, or preservatives
  • Food dyes
  • Rendered fats
  • Wheat, soy, or corn
  • Meat meals
  • Processed grains
  • Contaminants
