Cats vomit for various reasons. Sometimes, you’ll notice that they throw up their food right after eating or when they finally get that hairball out. Other times, the vomit is clear. You may notice that your cat is drinking large amounts of water and then throwing up. Why is this happening?
In this article, we look at the three most common reasons that your cat throws up after drinking water and what you can do about it. We also look at two less common reasons that this happens so you can be aware of all the possibilities.
Water vs Clear Liquid
In cat vomit, clear liquid and water are different things. Clear liquid is liquid inside the digestive tract that is being brought up and forced out. Water is usually thrown up right after the cat drinks it.
Clear liquid and water also have different consistencies. Clear liquid is thick and sticky, while water is thin and runny.
The 3 Reasons Why Cats Throw Up After Drinking Water
Here are the three most common reasons that cats throw up after drinking water. If you notice that this is happening often, consult your vet. Frequent vomiting, no matter what the substance, can be a sign of illness.
1. They Drank Too Much Too Fast — Most Common Reason
When cats eat or drink too quickly, their stomach fills up and stretches. This sends a signal to the brain that the stomach needs to be emptied. If the cat drinks too much too fast, they will regurgitate what they just consumed. That’s why your floor is now covered in water, and your cat goes back to eating and drinking normally like nothing happened.
This is the most common and most harmless reason for this behavior. However, if you notice it happening repeatedly, it could be a sign of something more serious.
2. They’re Trying to Vomit a Hairball
A buildup of hair can form in your cat’s stomach from grooming. As cats lick their coats, their rough tongues pull off loose hair, which they then swallow. When the hairball gets big enough in the stomach, cats have to remove it by vomiting. You’ll know that it’s a hairball because it will be a long, tube-like shape of a hair clump. The tube shape forms as the cat forces the hair through the esophagus.
After your cat drinks water, they may feel the urge to vomit a hairball. While trying to force the hairball up, some of that water can come up instead. Your cat can also vomit clear liquid before a hairball. This is the liquid in the digestive tract that comes up with the force of vomiting before the cat succeeds at removing the hairball.
3. They’re Hungry
When cats are feeling hungry, their stomach acids build up to prepare to digest a meal. These acids can irritate the stomach and cause nausea. When your cat vomits, all that will come up is clear liquid, mucus, and/or yellow or orange bile.
If your cat drinks water, this can cause the stomach acids to build up faster, irritating the stomach quickly and causing them to throw up the water along with the acids.
The 2 Uncommon Reasons Why Cats Throw Up After Drinking Water
The following two reasons for why your cat is throwing up after drinking water are not as common as the first three, but they are still good to be aware of. If you can’t determine why your cat is doing this, it’s best to ask your vet if one of the following possibilities could be the reason.
1. They Have Parasites
If your cat is suffering from a roundworm infestation, this is usually diagnosed by the appearance of worms in your cat’s poop. If the infestation is bad enough, it will cause vomiting. Your cat will often vomit any food or water that they consume if the worms are taking over their bodies.
Roundworms look like cooked spaghetti noodles. If you see them, there’s no mistaking what they are.
2. They Have a Metabolic Disorder
Certain diseases can increase your cat’s thirst. This will make them drink more water, sometimes too quickly, and then throw it up. An increase in your cat’s thirst is always a cause for concern because it’s a sign of several serious illnesses. Diabetes, kidney disease, and hyperthyroidism are just a few health conditions that can lead to cats drinking more water than they used to.
There are several reasons that your cat will throw up after drinking water. Some of them are nothing to be concerned about, but if it happens frequently or is combined with other signs, it’s best to have them checked by a vet to rule out any health problems.
