How to make a cat vomit

Our beloved cats are so curious that sometimes they can put something in their mouth that is not entirely appropriate for them. They can swallow any substance that they find pleasant to taste, or by being distracted by playing “hunting”.

Of course, not all the substances or objects that our felines find are not edible and some are even very dangerous. What can we do when this happens?

What is vomit?

First of all, I think it is important that we know what vomiting is and why we should go to the vet. Vomiting is the expulsion of gastric contents through the mouth. You will always have nausea, retching and will make abdominal effort to be able to expel the greater gastric content.

When in doubt, his thing is that you call the veterinary center you usually go to. Tell him what the case is so he can assess the seriousness of the situation .

Here are some situations in which you should take your cat to the veterinary center if it vomits :

  • In kittens under one year of age.
  • If you suspect that you have ingested human medications or a toxic substance (snail poison, rodenticides, etc.)
  • If you suspect that a foreign body has been eaten, such as string, thread, needles, etc.
  • If you vomit very frequently or the vomiting is persistent.
  • If in the vomit we find bilious content, blood or something similar to “coffee grounds”.
  • If during the day you vomit more than 2-3 times.

How do I know if my cat is nauseous?

Our friends have a very subtle way of expressing nausea. As a first indication they can stop eating . Other times he will have a slight drooling and make movements with his tongue , as if licking the remains of food from his mouth.

The ideal is, of course, to go to the vet, but if we live far from a clinic it is important to know how to make a cat vomit and when not to induce vomiting.


When should NOT make a cat vomit?


As bad as we see it, we do not have to induce vomiting under any circumstances if you have swallowed chlorine, gasoline, or any product that is used to maintain the car or to clean the home . That is, any product that is corrosive. The reason is that by ingesting it the animal has already caused damage and if we induce vomiting, the damage to the esophagus is enhanced when the corrosive joins with the acidic juice of the stomach. It is important to ensure that there are no remains on the ground.

Also, if more than two hours have passed since the animal ingested the toxic product or the foreign object, vomiting cannot be caused. This is because after two hours it will have passed into the small intestine and in the case of toxic substances, part will have been absorbed by it. In this case it is urgent and of vital importance that you go to the nearest veterinary center you have.

Activated charcoal can be given to prevent it from absorbing the poison. Activated charcoal can be found in any pharmacy without the need for veterinary pre-registration. We will use about 4-5 tablets of activated carbon diluted with a little water, for a cat of about 3-4 kg.

Another case in which the cat cannot be made to vomit is if the animal is unconscious because there is a risk of suffocation by aspiration .

Asphyxia by aspiration is based on the fact that when the animal is not conscious or has an object that obstructs the airways and the gastric content can pass to the lungs because the epiglottis partially closes the passage or does not close it.

When to make a cat vomit?

Not everything that our four-legged friend eats is directly dangerous for him. But we do have to keep an eye on him if we suspect he has eaten something he shouldn’t have. Be especially careful with home air fresheners , many times we choose sweet smells that for them are “palatable”. Herbs or plants that have been treated with herbicides.

How to make the cat vomit?


Of course, vomiting will be induced if the vet tells us to.

At home we can induce vomiting with hydrogen peroxide of 3% purity. You will be given 5ml of 3% hydrogen peroxide, which amounts to a teaspoon of coffee. At home we will not give more since it can be harmful to the animal by not having enough training or means. It is important that after giving the hydrogen peroxide dilution we make the animal walk so that it is more effective.

Once the cat has vomited, it will be administered activated charcoal in the doses mentioned above in this post.

One of the main situations in which we think about how to make a cat vomit is because it has eaten some of the plants that we have at home. Next, I leave you a list of the plants that we normally have in our homes and gardens and that are toxic to cats.
