When you love your cat as much as you do, it can be quite scary when they start doing something unexpected, like coughing or gagging after drinking water.
There are several reasons for this behavior, many of which are nothing to worry about. That said, certain health conditions might also cause it, so it’s essential to understand the source to ensure that your cat is healthy and safe.
The 7 Reasons Why a Cat Coughs After Drinking Water
1. Drinking Too Quickly
Just about anyone will likely cough after drinking too quickly, and cats are no different. When lapping up water too fast, it can accidentally enter the windpipe, which will cause coughing.

2. Drinking Excessively
Cats are not known to be big water drinkers, so if your cat seems to be gulping water down regularly, this might be a sign of an illness, such as:
Urinary tract infection
Kidney disease
Liver disease
Diabetes
Hyperthyroidism
These conditions tend to have a range of different signs, but an increase in thirst is often one of the early signs that something isn’t quite right. Try and take note of how much your cat is drinking in a 24 hour period and book an appointment with your vet for an examination. With all of these conditions, an early diagnosis makes treatment more likely to be successful.
3. Something Wrong With the Water

Your cat’s water might taste funny or perhaps it’s too cold. Cats can be highly sensitive to tastes and temperatures, and they can taste some things more acutely than we do. So, if the water has a large amount of chlorine or just tastes funny, it could cause a cat to gag which may be mistaken for coughing.
Solutions to this include:
Use filtered water instead of tap water.
Change the plastic bowl to ceramic or a stainless-steel cat water fountain.
Move the bowl or fountain away from the food source or litter box, etc.
Only use room temperature/cool water, not cold.
4. Something Obstructing the Throat
If something is stuck in a cat’s mouth or throat and drinking dislodges it, the cat will likely cough. If your cat has something that is obstructing their throat, they may be highly sensitive in this area, in which case coughing will occur more easily. Examples of things that might cause obstruction in the throat include;
Small bones, particularly fish bones
Hairballs
Polyps or tumors
Food that hasn’t been properly chewed (common in cats with dental problems)
A collar that is too tight (you should be able to slip two fingers under it)
Foreign object in the water (this can be hair or anything else that your cat accidentally laps up)
If the coughing and gagging continue, your cat requires a visit with your vet. In some cases, the obstruction will clear up on its own, but in others, a vet examination will be needed.
5. Allergies

There are several allergies that cats can suffer with. These include both food and environmental allergies. But while a cat with allergies might cough after drinking water, they are also likely to cough throughout the day.
Signs of allergies in cats can include:
Coughing, wheezing, and sneezing
Red, inflamed skin
Vomiting and diarrhea
Itchy eyes and skin
Swollen paws
Eye and nose discharge
You’ll need to see your vet if you believe that your cat might have allergies.
6. Respiratory Infection
Feline respiratory infections are fairly common, and generally are viral origins, but they can also be bacterial or fungal. The cat flu viruses (which can be vaccinated against) are common offenders when it comes to a cat with a respiratory infection, and these include feline herpesvirus (FHV-1) and feline calicivirus (FCV). Signs of a respiratory infection in cats can include:
Coughing and sneezing
Eye and nose discharge
Labored breathing (can sound congested)
Loss of appetite
Your vet can determine what infection your cat has and provide supportive treatment, to help your cat recover more quickly. Unfortunately, many of the cat flu viruses will remain latent and will reappear throughout a cat’s life.
7. Heart Issue

Hypertrophic cardiomyopathy (HCM) is the most common form of heart disease in cats, where one in seven cats will develop it in their lifetime. However, many cats will not show any sign of there being a problem until the disease is fairly well progressed.
Like our own, a cat’s heart has 4 chambers; two small ones at the top (the atria) and two large ones at the bottom (the ventricles). The heart’s left ventricle works to pump oxygen-rich blood to the rest of the body. Hypertrophic cardiomyopathy occurs when the muscular wall of the left ventricle enlarges and thickens, making the chamber smaller and less able to pump blood around the body. The harder the left ventricle works, the thicker the muscle of the wall becomes and the smaller the chamber becomes.
The physical signs of HCM can include:
Loss of appetite
Tiring easily during exercise and play
Wheezing and crackling sounds when breathing
Difficulty breathing
Abdominal swelling from the accumulation of fluid
Pale, blue, or gray gums
Blue nail beds and foot pads
Weakness/lethargy
Collapse
Sudden death
Your vet will need to run tests, including a physical exam, blood work, and echocardiogram.
Should You Worry If Your Cat Coughs After Drinking Water?
If your cat has done this on the odd occasion, and seems to be fine afterwards, there may be nothing to worry about. That said, you should still speak to your vet to rule out the possibility of something more serious and for your peace of mind. If your cat has started to cough, be it after drinking water or other times of day, it is essential that you book in with your veterinarian.
You can try a few of these tips to see if any of them makes a difference, but if you are concerned about your cat’s health, a trip to the vet is in order.
Use a new water bowl or fountain made with glass, ceramic, or stainless steel. Try to avoid plastic.
Use a fountain if your cat tends to paw at the bowl.
Provide filtered water over tap water.
Ensure that your cat’s collar fits correctly (you should be able to slide two fingers under the collar).
Keep the water at room temperature.
Clean and refill the water bowl twice a day.
Give your cat multiple bowls in different locations in your home.
Move the bowl or fountain to a stress-free area (away from noisy appliances or high-traffic areas).
Move the bowl or fountain away from the litter box and food bowls.
Take your cat to your veterinarian for regular annual checkups or anytime you’re concerned.
Conclusion
Some cats simply cough after drinking water, which can be chalked up to a unique trait. But if your cat suddenly starts coughing, it’s best to take them to the vet to rule out the possibility of something serious.
Keeping hydrated is vital for a healthy cat, as dehydration can lead to serious complications. But if your cat is in good health, perhaps a few of the tips here can help your cat drink more comfortably.
