Introduction – Is Your Cat Drinking a Lot of Water and Meowing?
Most people assume that a cat drinking a lot of water is a good thing. They think, “At least my cat is staying hydrated, so there’s nothing to worry about.” But that’s not always true. When a cat drinks a lot of water and meows more, it can be a sign that something is wrong.
If your cat suddenly can’t stop drinking water or is constantly vocalizing near the bowl, don’t ignore it. Cats are naturally quiet animals. When they meow nonstop, cry loudly, or act restless while drinking, they’re often trying to show discomfort, stress, or even illness.
In this guide, we’re going to break down the real reasons behind a cat drinking too much water and meowing—without confusing medical jargon. We’ll talk about what’s normal, what’s not, and when it’s time to take things seriously. This is especially important if your older cat is drinking a lot of water, meowing at night, or showing sudden behavior changes.
How Much Water Should a Cat Normally Drink?
Before we panic, let’s start with the basics—how much water should a healthy cat really drink?
A normal cat needs around 3.5–4.5 ounces (100–135 ml) of water per 5 pounds of body weight per day. That means if you have a 10-pound cat, they should be drinking roughly 7–9 ounces of water daily. But here’s the twist: cats who eat wet food typically drink less because they’re already getting moisture from their meals. Cats on dry kibble often drink more because their diet is dehydrating.
So when is it too much? If you see your cat suddenly drinking a lot of water, going back to the bowl often, or finishing the whole dish every few hours, something might be wrong. That’s when words like polydipsia (excessive thirst) come into play.
Pay attention to changes. If your cat usually drinks little but now can’t stay away from the water bowl, pay attention. If they’re also meowing a lot, crying, or acting restless, it’s time to keep a closer eye on them.
Here are quick indicators that water intake may be abnormal:
- Drinking more than usual for several days in a row
- Meowing loudly before, during, or after drinking
- Hovering over the bowl like they’re never satisfied
- Urinating more than usual (or sometimes less)
- Drinking water and acting weird or anxious
These signs might connect to health issues such as diabetes, kidney disease, hyperthyroidism, or urinary infections. But don’t worry; we’ll discuss those in the next sections.
For now, the most important step is to observe your cat’s water habits, behavior, and vocalization patterns. This helps you notice small changes before they become big health problems.
Warning Signs – When Excessive Drinking & Meowing Means Trouble
A lot of cat owners think, “My cat is just thirsty and talkative. They’re probably fine, right?” But that assumption can be dangerous. Cats don’t often show clear signs when they’re unwell. So, drinking a lot and meowing constantly can be early warning signs of a health problem.
If your cat starts hovering by the water bowl, crying loudly, yowling at night, or drinking more than usual, don’t brush it off as “just a phase.” This could be an early sign that something isn’t quite right inside their body.
Here are the key red flags you should watch closely:
🔍 Signs Your Cat’s Behavior Is Not Normal
- Drinking water repeatedly throughout the day (more than usual)
- Meowing loudly before or after drinking
- Visiting the litter box more often or barely urinating at all
- Losing weight while still eating normally
- Sudden behavioral changes, restlessness, or aggression
- Drinking but not eating food
- Crying or yowling at night
- Acting dehydrated even when drinking water
If you’ve noticed a cat drinking water and acting weird, especially when paired with nonstop vocalization, the safest move is to contact a vet.
Remember: cats are masters at hiding pain. Excessive thirst + unusual meowing is their version of waving a red flag.

Main Medical Causes of Excessive Drinking + Meowing
Many people don’t know that if a cat drinks a lot of water and meows a lot, it may signal medical issues—not just its personality or mood. Let’s break down the most common causes in a simple, clear way.
4.1 Feline Diabetes
If your cat is drinking excessive water suddenly, losing weight, begging for food, and crying at odd hours, it could be diabetes. This condition causes high blood sugar, which leads to constant thirst and frequent urination.
Common Signs:
- Always hungry
- Sudden weight loss
- Sticky or sweet-smelling urine
- Meowing for food or water nonstop
4.2 Kidney Disease (CKD)
Kidney problems are very common in older cats. When the kidneys stop working properly, they can’t filter waste, so the cat drinks more water to compensate. That’s why many pet owners notice their older cat drinking too much water and vocalizing.
Warning Signs:
- Increased thirst and urination
- Bad breath (ammonia-like smell)
- Vomiting or nausea
- Tiredness and poor coat condition
Early detection can save their life, so don’t delay a vet visit if these signs appear.
4.3 Hyperthyroidism
This condition speeds up your cat’s metabolism. That means they burn energy fast, meow more, eat more, and drink much more than usual. You’ll often see a cat meowing loudly and drinking water constantly, especially at night.
Signs to Watch:
- Always active or restless
- Weight loss despite eating more
- Racing heartbeat
- Loud or nonstop vocalizing
4.4 UTI or Urinary Tract Issues
A cat with a UTI, bladder inflammation, or blockage often drinks more because they’re uncomfortable. They may cry, strain, or vocalize in pain while urinating or after drinking.
Possible Signs:
- Frequent trips to the litter box
- Meowing during urination
- Blood in urine
- Sudden aggression or hiding
- Licking the private area constantly
A UTI can turn into a life-threatening emergency—especially for male cats—so immediate treatment is crucial.
4.5 Stress or Behavioral Causes
Sometimes, a cat is not sick at all—but stressed. Changes in routine, new pets, boredom, or anxiety can trigger excessive meowing and drinking behavior. Cats may cry just to seek attention, food, or reassurance.
However, even if it is behavioral, you should rule out medical causes first.
Quick Recap
If you see any combination of:
- Constant drinking
- Loud or nonstop meowing
- Changes in eating or urination
- Sudden behavior changes
…don’t wait. Get your cat checked. Most diseases that cause excessive thirst and vocalizing can be treated if caught early.
Behavioral Causes (Non-Medical Reasons)
Many people think that if a cat drinks a lot of water and meows, it must be sick. But that’s not always the case. Sometimes, your cat may be perfectly healthy—they’re just responding to stress, changes, or emotional triggers.
Cats are creatures of habit. Even small changes—like new furniture, loud noises, a new pet, or shifting feeding times—can result in odd behaviour. They may start crying near the water bowl, drinking more for comfort, pacing, or meowing for attention.
Here are some common behavioral causes that can lead to excessive meowing and drinking:
Attention-Seeking Behavior
Cats quickly learn that meowing = human attention. If your cat cries every time they go near the bowl and you respond, they’ll repeat it—even if they’re not really thirsty.
Environmental Changes
Moving to a new home, a new baby, visitors, or even changing where their water bowl sits can trigger anxiety.
Boredom or Lack of Stimulation
A bored cat may drink water out of habit or cry just to get interaction. Indoor cats need mental and physical stimulation to stay calm.
Feeding Schedule Changes
If you started feeding later or changed food brands, a cat might meow for no reason (at least from your perspective). They may also drink more to feel full.
Senior Cats
Older cats sometimes become more vocal and confused due to age-related cognitive changes. They may cry at night, drink more water for comfort, or wander the house making noise.
Even if you strongly suspect the cause is behavioral, it’s still smart to rule out medical issues first. A cat can act stressed because they’re sick—so never assume behavior = harmless without checking.
What to Do If Your Cat Is Drinking a Lot & Meowing Nonstop
Most people respond by giving more food, changing bowls, or telling the cat to “be quiet.” But that won’t fix the real issue. If your cat is drinking water and meowing constantly, you need a plan that focuses on both observation and care.
Here’s what to do step-by-step:
Step 1: Track Water Intake & Behavior
Start monitoring how often your cat drinks. Even writing it down helps. This will allow your vet to see if the behavior is consistent or worsening. Also, note when the meowing happens—before water? After? At night?
Step 2: Check the Litter Box
More water means more urine. If your cat is peeing a lot (or not peeing at all), that can tell you a lot about their health. Don’t skip this step.
Step 3: Assess Eating & Activity Changes
Is your cat eating more? Less? Losing weight? Acting restless? These clues help identify serious issues like diabetes or hyperthyroidism.
Step 4: Schedule a Vet Exam
If your cat continues drinking excessive water suddenly, meowing loudly, or acting weird, it’s time to see a vet. A professional can check for:
- diabetes
- kidney disease
- thyroid problems
- UTIs
- dehydration
- pain or stress
Step 5: Provide Comfort & Hydration at Home
While waiting for testing or treatment:
- Always keep fresh, clean water available
- Use a pet fountain to encourage healthy drinking
- Keep noise low and routine consistent
- Offer comfort, but don’t reward excessive crying
- Add wet food to help hydration naturally
Step 6: Don’t Ignore Subtle Symptoms
Even if your cat looks fine physically, constant drinking and meowing are still major signs that something has changed inside the body or mind. Early care prevents bigger health problems later.
What Your Vet Will Check & Diagnose
Many cat owners think, “If my cat is drinking a lot of water and meowing, it’s just a phase or a personality quirk.” That’s a common misconception. Some cats are naturally chatty, but if your cat drinks a lot and meows constantly, it could mean there are serious problems. That’s why a vet visit is crucial.
Here’s what your vet will usually check:
1. Blood Work
Blood tests help detect conditions like diabetes, kidney disease, or infections. High blood sugar, kidney issues, or electrolyte problems can cause your cat to drink a lot or meow more than normal.
2. Urinalysis
Urine testing reveals issues like urinary tract infections (UTIs), kidney problems, or crystals. Cats often drink more water to compensate for urinary discomfort, and you might notice them meowing near the litter box or water bowl.
3. Thyroid Levels
Hyperthyroidism is common in older cats. Too much thyroid hormone speeds up metabolism. This causes weight loss, increased thirst, and loud or constant meowing, especially at night. A simple blood test can identify this condition.
4. Imaging (X-rays or Ultrasound)
If the vet thinks there might be kidney disease, bladder problems, or other internal issues, they may suggest imaging. This points out any structural problems that might cause polydipsia (excessive thirst) or ongoing vocalisation.
Home Care Tips While You Wait for the Vet
Even before your vet appointment, there are ways to support your cat and make them comfortable. Many owners worry they can’t do anything at home, but simple steps can help manage stress and hydration.
1. Ensure Fresh Water
Always provide clean, fresh water. Some cats prefer running water from a fountain—it encourages drinking without forcing them to overdrink from a single bowl.
2. Offer Wet Food
Wet food contains high moisture content, which helps maintain hydration. This is really helpful for cats that drink water and meow a lot. It eases the strain on their kidneys and keeps them happy.
3. Create a Calm Environment
Stress can worsen meowing and drinking behavior. Keep their space quiet, maintain routine feeding times, and avoid sudden changes in the household. A cozy bed or safe hiding spot can help.
4. Monitor Behavior & Symptoms
Keep notes on water intake, litter box visits, and meowing frequency. This info is crucial for your vet. It helps spot patterns that might show issues like diabetes, UTIs, or kidney problems.
5. Avoid Self-Medicating
Don’t give your cat human medications or supplements without vet approval. Some remedies may worsen dehydration, kidney problems, or upset their digestive system.
Key Takeaway: While you wait for care, focus on staying hydrated, being comfortable, and observing closely. Managing stress and providing a supportive environment can help your cat feel more at ease while you prepare for the vet visit
How to Prevent Excessive Thirst & Meowing in the Future
