Cats are animals that bear pain so well that they will only complain when they can't take it anymore. It is, therefore, very necessary to pay attention to any changes that occur in their behavior in order to more quickly identify the discomfort of our friend, and act accordingly.
One of the most worrisome symptoms is excessive salivation. Sometimes it may not mean anything serious, but in others it will be necessary to go to the vet as your life could be in danger. That being said, if you are wondering why does my cat drool a lot, here you will find your answer.
Origin of excessive salivation

Excessive salivation, also known by the name of ptyalism, can have very different origins. There are more and less serious, and they are the following:
Poisoning
If your furry has ingested something bad, or if he goes outside and has eaten grass treated with insecticide, one of the first symptoms will be drooling. But it will not be a bit of saliva and that's it, but it can act like foam, that is, that it can expand and cover the entire mouth. It can also happen if you have put a pipette on it or have sprayed it with flea and tick spray and it has licked it, thus ingesting the product.
It is very dangerous, so if you see your friend drooling like this, remove it with a dry cloth quickly. If you think your cat may have been poisoned, these are the symptoms of poisoning in cats.
Mouth pain
If you have suffered a trauma, if you have an infection in the teeth, tartar, and / or inflamed gums, you will have trouble swallowing the saliva produced, so it will tend to 'take it out'.
This occurs especially in elderly cats, when they already begin to have osteoarthritis, but even if your furry is younger, you must not lower your guard.
Stress or fear

When humans are stressed or afraid, we feel our pulse racing, our pupils dilate, and our body prepares to fight or flee. Well, in the case of cats something similar happens, but in addition to this set of symptoms drooling is added.
One of the most common situations that we will see that he drools will be when we have to take him to the vet. Virtually no animal likes to go there, so there are many who, since they cannot control the situation, they produce more saliva than necessary.
Nausea and / or vomiting
A cat that is nauseous and / or vomits tends to drool a lot. It usually worries us a lot, but if vomiting is sporadic and the animal is fine, it may have simply swallowed some hair and tried to expel it. However, If it is accompanied by other symptoms or if you start to vomit for several days in a row, then you should go to the vet as you could have hairballs, an internal parasite infection, or a serious digestive tract disease.
Foreign body in the mouth

If you give your cat scraps of your food, especially if you give him fish or chicken, it is convenient that remove both thorns and bones since they could stick in the mouth or in the neck of your cat, causing him a lot of pain and of course also excessive salivation.
You can give fish and meats without problem, but cleaning the fish well before. The bones must always be raw, otherwise they could splinter. It is very important too give them those that are bigger than their mouths so that he is forced to chew it. This way he can enjoy a delicious and natural meal, and you won't have to worry  .
For pleasure
It is not frequent, but there are cats that drool a lot when they are very relaxedsimply because they feel very comfortable. They can also do it when they smell their favorite food and know that you are going to give it to them at any moment.
I, if I tell you the truth, I have not seen this behavior in my cats, but in one of my dogs. The amount of saliva that can be 'expelled' is impressive when she's happy, or when she's nervous because she knows we're going to go somewhere she loves.
To do? Nothing, just enjoy seeing your furry happy. What better gift than that?

Excessive salivation or ptyalism is a reaction of the body to something that is harming it, as in the case of foreign bodies in the mouth, or for tranquility, relaxation and / or happiness. It will depend on the origin whether or not to go to the vet, but what we do need to know is that, whenever the cat is not well, paying him a visit doesn't hurt Well, as we have seen, drooling can be an indicator of disease.
I hope this special has solved your question about why my cat drools a lot. If in the end you have a problem, a lot of courage and calm, what recovery is usually quick. It will soon be the same as always  .
