Cat Supplies | Cats

Older cats often have sensitive stomachs, and this can make them vomit regularly when their food doesn’t quite agree with them.

Giving them an improper diet will make an already bad situation worse, and it is important to make careful consideration of the type of food you buy for your feline companion. 

The best cat food for older cats that vomit are diets are made with limited ingredients that are gentle to your cat’s stomach, and that your fussy cat will love. They are also balanced and complete to provide all the necessary nutrients that cats require. 

Typically the main cause of food sensitivities in older cats may be changes in the ingredients that the cat is allergic to, strong smells, or the cat may be suffering from a condition that is more than just stomach gases. 

The immediate reaction for cats with sensitive stomachs is to throw-up. The vomit may be a yellowish or brownish thick substance with a strong smell, and your cat may appear to be listless and uncomfortable after vomiting.

While it is common for cats to throw up once in a while, you should monitor their condition to make sure it is nothing serious. If your cat has fever or diarrhea it may be a sign of something serious, and you should visit a vet immediately.

What Causes Cats to Throw Up?

Here are a few reasons why cats may throw up:

Change of diet

Frequent changes in the cat’s diet may result in vomiting because their stomach will treat the meal as a foreign substance that their body is yet to get used to.

When introducing a new diet, the ideal method is to make the change gradual and not immediate.

This gives your cat time to get used to the new diet before they can feed solely on the new food source.


Giving your cat too much food causes discomfort in the stomach and vomiting is inevitable.

Overfeeding mostly occurs when you leave a full bowl for the cat to eat.

Usually when you try to explain to your cat that they eat too much they simply ignore you, or look at you with absolute distain!

Most cats are unable to control their eating habits and will eat until their food bowl is empty. Allowing your cat to eat too much food may result in serious conditions such as diabetes and obesity.

If you spend a fair amount of time away from home, you can use an automatic cat feeder that schedules meals automatically to make sure your cat eats a small portion in given time intervals.

This way you will have control over the amount of food that your cat eats while you are away. 


Cats are heavy groomers and they will ingest some of their hair, which combines to form a hairball.

The hairball is a round ball of hair strands that may cause blockage of the food tract, and this will make it difficult for your desperately hungry kitty to swallow food.

The result of this will be your cat throwing up to remove the foreign substances, followed by you having to clean up the mess left on your otherwise clean floor.


When choosing the best cat food for older cats that vomit, you should give careful consideration to the list of ingredients in the formula.

Stay away from diets that your cat has reacted to in the past, or that contain questionable ingredients.

It is also good to seek your vet’s recommendation on the best diet for your older cat.

That way you will be sure that you are giving your cat the right choice of diet.

Happy kitty, happy you!
