Finding out that my dear cat is foaming at the mouth is quite upsetting. It’s important for me to know that excessive drooling or foaming in cats is not usual and could mean there’s a health problem.

In this article, I’ll look into the reasons why cats foaming at the mouth, trying to understand why it happens. I’ll also talk about when it’s important to go to the vet, helping me figure out when my furry friend might need professional help.

Reasons Why Cats Foam at the Mouth

Dental Disease:

If I notice that my cat is drooling a lot or foaming at the mouth, it could be because of dental problems like gingivitis and tooth decay. Signs such as bad breath, plaque on their teeth, or red, swollen gums may indicate periodontal disease.

If my cat is struggling with eating or drooling excessively, I know it’s crucial to set up a vet appointment to discuss their oral health. Ignoring this issue might only make it worse with time.

I understand that certain forms of periodontal disease can be prevented, so I make sure to talk to my vet about the best practices for my cat’s oral health.

There are different toothpaste and toothbrush options for at-home dental care, and during my cat’s annual checkup, their teeth are examined.

If advanced treatment for periodontal disease is needed, it may include professional cleaning, polishing, and, in some cases, surgical removal of affected teeth.

Taking these steps ensures the well-being of my furry friend.

Ingesting Something Harmful:

If my cat suddenly starts foaming at the mouth and drooling, it might be because they ate, breathed in, or absorbed a harmful substance, like a toxin or poison. There are different signs of poisoning in cats, such as:

  • Foaming or drooling from the mouth
  • Diarrhea
  • Panting
  • Faster heartbeat
  • Increased thirst
  • Fever
  • Being tired all the time
  • Seizures
  • Not wanting to eat
  • Throwing up
  • Hiding
  • Feeling weak
  • Trouble walking
  • Restlessness
  • Peeing more than usual
  • Yellowing of the skin, eyes, or gums

Things like fertilizers, plants, household cleaners, human medicine, and certain foods can be common toxins for cats.

Cats often like to nibble on plants, but many can make them very sick. Keeping these harmful things away and safeguarding your plants can help prevent your cat from getting sick.

If I think my cat ate something harmful, I’ll contact my vet right away or take them to an emergency hospital.

Helping My Cat Deal with Stress:

Sometimes, my cat might start drooling or having foamy saliva when feeling stressed or anxious. This can happen for various reasons, like loud noises, new people or animals, changes in routine, or being away from me.

Because stress can affect my cat’s health, it’s important for me as a pet owner to help them feel better. Here are some ways I can make my cat more relaxed:

  • I can figure out what’s stressing them and try to make it less scary, like reducing loud sounds or giving them a safe hiding spot.
  • Using calming things like special scents (pheromones) or products like Feliway can help my cat feel better.
  • If my cat is scared of certain sounds, I can slowly let them get used to those noises gently.
  • Keeping a regular schedule, giving them fun toys, and letting them do things they enjoy can also make my cat feel more comfortable.

Watching Out for Vaccination Reactions:

When my cat gets vaccines, they might have a little reaction, like making frothy saliva. In rare cases, this can be serious and even cause choking. If that happens, I need to get help from the vet right away.

Some cats are more likely to react because of their genes or allergies. It’s smart to talk to the vet before vaccinating my cat.

Recognizing and Helping with Seizures:

If my cat shakes, drools, or seems to lose control, they might be having a seizure. It’s scary, but I can help by staying calm and calling the vet for advice.

While waiting for help, I can talk to my cat in a gentle voice, keep things quiet, and avoid bright lights.
If my cat isn’t in danger, it’s best not to touch them during a seizure.

  • I should make sure they have a shady spot to rest and fresh water to drink.
  • If my cat seems too hot, I can cool them down by wetting their fur with cool water.
  • If things don’t get better, or if my cat acts sick, it’s important to take them to the vet.

What to do if your Cat is Foaming at the Mouth?

If you happen to notice your cat foaming at the mouth, it can be a bit alarming, but there are a few things I can do to make sure they get the care they need. First off, I’ll keep an eye out for other signs.

A little bit of drool might not be a big deal, but if my furry friend seems upset, isn’t eating, is throwing up, or shaking, it’s time to take action and seek immediate medical help.

When I head to the vet, they’ll do a thorough checkup and probably ask about my cat’s medical history and any possible contact with other animals or harmful substances.

There could be various reasons for the excessive drooling, so it’s crucial to get professional guidance.

If it turns out to be a dental issue, my vet might suggest cleaning my cat’s teeth or, in more severe cases, removing a tooth. In case of toxin ingestion, quick veterinary care is a must. If I can, I’ll bring a sample of the suspected poison.

Treatment may involve inducing vomiting, using charcoal to absorb toxins, and providing IV fluids. If a respiratory infection is suspected, my vet may order blood work and x-rays.

They’ll inquire about my cat’s interactions with other cats to prevent the infection from spreading. Treatment may include fluids, antibiotics, and restorative measures to combat the infection.

My cat might need some rest, proper nutrition, and even oxygen therapy to recover from an upper respiratory viral infection. The key is to act swiftly and get my feline friends the care they need.

Prevention of Foaming at the Mouth

If you’ve ever seen your cat foaming at the mouth, you know it’s not something any pet owner likes to see. While I get that stopping it from happening every time might not always work, I’ve found that doing things ahead of time can really help my cat stay healthy.

Eating the Right Stuff:

When I think about what my cat eats, I make sure it’s a good mix. I think about how old they are, what breed they are, and if they have any health issues.

I look for cat food and extra things to eat that are made just for them. I try to get food that has about 30-45% protein – that’s like the building blocks for a healthy body.

Some amino acids, especially taurine and arginine, are super important for their heart and to stop health problems. I know cats need a lot of good animal protein, so I pick food with that. And a bit of fat, like 15-25% of their food, gives them energy.

Keeping Things Safe at Home:

I make sure where my cat lives is safe. No harmful plants, dangerous chemicals, or small things could be eaten. Making their home safe helps stop accidents and health problems.

Watching Outdoor Time:

Since my cat likes being outside, I always keep an eye on them. I watch to make sure they don’t get near things that could be bad for them, like toxins or harmful plants. I might use a leash or make a special outdoor space just for them.

By doing these things and making them part of my cat’s routine, I’m not just stopping problems – I’m making sure my cat stays healthy and happy.

It’s a reminder for me that keeping issues away is the key to having a happy and well-cared-for cat.

Rinse with Water:

If it’s safe, I can use a syringe or gently let water from the faucet flow into my cat’s mouth. This might help get rid of things that could be bothering them. I just need to be careful not to push water too hard into their throat.

Check for Objects:

I can take a good look inside my cat’s mouth and throat to see if there’s anything stuck making them foam. I need to be really gentle and careful so I don’t get bitten or hurt my cat more.

Flush with Water:

If I see something stuck and it’s safe to do so, I can try using a syringe or a turkey baster to gently wash my cat’s mouth with a bit of lukewarm water. But I need to be very gentle to avoid making the thing go deeper.

Keep Away from Other Pets:

If I think my cat ate something bad, I should keep them away from my other pets. This helps stop the problem from spreading.

Don’t Make Them Eat or Drink:

It’s not a good idea to make my cat eat or drink if they don’t want to. It could make things worse or cause them to choke.

I should remember, that these are just simple things to try, but if my cat is really not doing well, it’s super important to call the vet. They can give me the best advice and make sure my cat gets the right care.
