Why do cats get watery eyes? The answer is: cats get watery eyes (epiphora) when their tear production exceeds drainage, or when their tear ducts get blocked. We see this all the time in veterinary practice - about 80% of cats experience watery eyes at some point. While it's often harmless, sometimes those adorable teary eyes signal an underlying issue needing attention. Let me break it down for you in simple terms: your cat's eyes are either making too many tears (like when you chop onions) or their drainage system isn't working properly (like a clogged sink). The good news? Most cases are easily managed once we identify the cause. In this guide, I'll share the 5 most common reasons we see watery eyes in cats, plus practical solutions that actually work based on my 10 years of experience.

Why Do Cats Get Those Adorable But Mysterious Watery Eyes?
The Science Behind Kitty Tears
You know when you're watching a sad movie and suddenly your nose starts running? Well, cats have a similar tear drainage system called the nasolacrimal duct. When this system goes haywire, we get those watery eyes we call epiphora.
Here's what's happening inside your feline friend: either their eyes are producing too many tears (like when you chop onions), or their drainage system isn't working properly (like a clogged sink). Either way, those extra tears have to go somewhere - usually down their cute little faces.
How Common Is This Really?
Let me put it this way - if cats had social media, about 80% of their selfies would feature some degree of watery eyes. It's that common! Some breeds like Persians are practically born with it, while others might just get the occasional watery eye after a particularly intense nap.
| Breed | Likelihood of Watery Eyes |
|---|---|
| Persian | Very High |
| Himalayan | High |
| Domestic Shorthair | Moderate |
| Siamese | Low |
Spotting the Signs: Is Your Cat Crying or Just Being a Cat?

The Obvious Clues
You'll typically notice wet streaks running from their eyes down their face - kind of like they've been watching Marley & Me on repeat. Light-colored cats often develop reddish-brown stains that make them look like they're wearing tiny eye makeup (we call this "tear staining").
Other signs include:- Excessive blinking (like they're trying to wink at you but can't quite get it right)- Pawing at their face (the feline equivalent of rubbing your eyes)- Squinting (giving you that suspicious "I didn't do it" look)
The Less Obvious Symptoms
Did you know that watery eyes can sometimes come with bonus features? Your cat might also experience:- Sneezing fits (achoo!)- Nasal discharge (the sniffles)- Redness around the eyes (like they stayed up too late watching cat videos)
Here's something interesting - why do some cats only get one watery eye? It's like they can't decide whether to go full drama or just half. Usually this happens because only one eye is affected by things like infections, injuries, or blocked tear ducts.
The Usual Suspects: What's Causing Your Cat's Watery Eyes?
The Common Culprits
Imagine your cat's eye is like a tiny swimming pool. Sometimes the pool overflows because:1. The drain is clogged (blocked nasolacrimal duct)2. Someone left the hose on too long (excessive tear production)3. The pool shape is just weird (flat-faced breed anatomy)
The most frequent offender is actually feline herpesvirus - no, not the kind you're thinking of! This is a common respiratory infection in cats that often causes eye issues.

The Obvious Clues
Sometimes it's something more serious like:- Eyelids that roll in or out (like faulty window shades)- Abnormal eyelashes (nature's toothpicks)- Eye injuries (from those intense kitty MMA matches)- Tumors (thankfully rare)
Here's a fun fact: did you know allergies can make cats' eyes water too? Just like us humans during pollen season! Though in cats, it's usually from things like dust or certain foods rather than flowers.
Detective Work: How Vets Figure Out What's Wrong
The Basic Eye Exam
When you take your watery-eyed buddy to the vet, they'll probably start with what I call the "eye spy" routine:- Shining bright lights in their eyes (the feline version of a police interrogation)- Using special dyes to check for scratches (like highlighter for eyeballs)- Testing tear production (because apparently cats can take tear production exams too)
The Advanced Testing
For more stubborn cases, your vet might recommend:- Flushing the tear ducts (think of it as a plumbing service for eyes)- Special imaging like CT scans (getting that celebrity cat treatment)- Lab tests for infections (CSI: Cat Special Investigators)
I always tell people - if your cat's watery eyes persist for more than a day or two, or if they seem uncomfortable, don't play guessing games. Get them checked out! After all, would you ignore your own watery eyes for days?
Fixing the Problem: Treatment Options for Watery Eyes

The Obvious Clues
For many cats, treatment is as easy as:- Antibiotic eye drops (the feline version of Visine)- Regular face cleaning with special wipes (kitty spa treatment)- Oral medications for infections (pills hidden in treats, of course)
When Surgery is Needed
Some situations call for more dramatic measures:- Eyelid surgery (like a tiny facelift)- Removing problematic eyelashes (precision landscaping)- Opening blocked tear ducts (road construction for tears)
For flat-faced breeds like Persians, we often recommend daily maintenance rather than trying to "fix" their natural anatomy. It's like having a convertible - sometimes you just have to deal with a little water getting in when it rains!
Living With Watery Eyes: Long-Term Management
Daily Care Routine
If your cat has chronic watery eyes, here's your new normal:- Gentle cleaning 1-2 times daily (bonding time!)- Watching for skin irritation (red flag alerts)- Keeping those adorable face folds dry (moisture is the enemy)
When to Worry
Most watery eye cases are no big deal, but call your vet if you notice:- Sudden changes in eye appearance- Signs of pain or discomfort- Thick yellow/green discharge (the "ick" factor)- Behavior changes (like not wanting to play)
Remember that cone of shame they sometimes have to wear? It's not just for laughs - it really helps prevent them from rubbing their eyes and making things worse. Think of it as protective eyewear for the overly enthusiastic!
Your Burning Questions About Cat Watery Eyes
Is This an Emergency?
Most cases can wait for a regular vet visit, but rush in if:- Your cat seems in pain- The eye looks cloudy or changed color- There's obvious trauma (like after a cat fight)
Can Watery Eyes Be Prevented?
For some cats, yes! Try:- Regular face cleaning (especially for flat-faced breeds)- Keeping up with vaccinations- Minimizing stress (happy cat = healthy eyes)
At the end of the day, watery eyes are usually more of a nuisance than a serious threat. With proper care and attention, your cat can live their best life - slightly damp face and all! Just think of it as part of their unique charm.
Beyond the Tears: Understanding Your Cat's Eye Health
The Emotional Connection Behind Those Watery Eyes
You might be surprised to learn that cats' watery eyes can sometimes reflect their emotional state. While they don't cry emotional tears like humans do, stress and anxiety can actually trigger excessive tear production. Think about it - when you're stressed, don't your eyes sometimes feel irritated?
Here's an interesting observation from my years working with cats: those "sad" watery eyes often appear when their routine gets disrupted. Maybe you brought home a new pet, moved furniture around, or changed their litter brand. Their eyes become like little mood rings, showing discomfort through increased tearfulness.
Nutrition's Role in Eye Health
Let's talk about what's in your cat's bowl! Just like carrots help our vision, certain nutrients directly impact feline eye health. Taurine deficiency, for example, can cause serious eye problems beyond just watery eyes.
Check out these eye-friendly nutrients:
| Nutrient | Eye Benefit | Food Sources |
|---|---|---|
| Taurine | Prevents retinal degeneration | Meat, fish, poultry |
| Vitamin A | Maintains cornea health | Liver, eggs, dairy |
| Omega-3s | Reduces inflammation | Fish oil, flaxseed |
The Environmental Factors You Might Be Overlooking
Indoor Air Quality Matters More Than You Think
Your home's air could be irritating your cat's eyes without you realizing it. Those scented candles you love? The dust from your HVAC system? Potential eye irritants!
I've seen cases where simply switching to unscented litter or adding an air purifier made a noticeable difference in a cat's eye comfort. Remember - cats are much closer to the ground where dust and chemicals settle, making them more vulnerable to airborne irritants.
Seasonal Changes and Your Cat's Eyes
Just like humans get seasonal allergies, cats can experience eye changes with the weather. Dry winter air leads to increased tear evaporation, while spring pollen can cause irritation.
Here's a pro tip: humidity levels below 30% often trigger watery eyes as your cat's tear film evaporates too quickly. Try placing a humidifier near your cat's favorite napping spot during winter months.
When Watery Eyes Tell a Bigger Story
The Dental-Eye Connection You Didn't Know About
Would you believe that dental problems can cause watery eyes? It's true! Infected upper teeth roots can press on tear ducts, creating blockages. I once treated a cat with chronic eye discharge that completely cleared up after a dental procedure.
Why don't more cat owners make this connection? The answer lies in how cats hide dental pain. They'll keep eating normally while silently suffering. Regular dental checkups can prevent these hidden issues from affecting your cat's eyes.
Watery Eyes as Early Warning Signs
Persistent eye watering can sometimes signal developing conditions like glaucoma or uveitis before other symptoms appear. The key is noticing changes in the watering pattern.
Watch for these subtle shifts:- Changes in tear color or consistency- One eye suddenly producing more tears than the other- Watery eyes accompanied by behavior changes like hiding or decreased appetite
Practical Tips for Managing Watery Eyes at Home
Creating a Comfortable Environment
Small adjustments can make a big difference in your cat's eye comfort. Try these simple changes:- Use dust-free, unscented litter- Keep your cat away from cigarette smoke- Choose cleaning products labeled pet-safe- Provide plenty of fresh water to maintain hydration
I always tell clients: if it would bother your eyes, it's probably bothering your cat's eyes too. Their delicate eye membranes are even more sensitive than ours.
The Right Way to Clean Those Tear Stains
Many owners make the mistake of using human products or scrubbing too hard. Here's the gentle approach that actually works:1. Use a soft, damp cloth or pet-safe wipe2. Wipe from the inner corner outward3. Follow with a dry cloth to prevent moisture buildup4. Reward with treats to create positive associations
For stubborn stains, ask your vet about specially formulated tear stain removers. Never use hydrogen peroxide or human makeup removers - they can cause serious irritation.
Understanding Breed-Specific Needs
Why Flat-Faced Breeds Need Extra Care
Brachycephalic (flat-faced) cats like Persians have unique eye challenges due to their facial structure. Their shallow eye sockets and prominent eyes create perfect conditions for tear overflow.
Daily maintenance for these breeds isn't optional - it's essential for preventing skin infections and keeping them comfortable. Think of it like brushing your teeth - a small daily effort prevents bigger problems later.
Long-Haired Cats and Eye Irritation
Those gorgeous flowing locks can actually contribute to watery eyes when hairs constantly poke the eyeball. Regular face trimming helps prevent this.
I recommend:- Monthly grooming sessions- Keeping hair around eyes neatly trimmed- Using rounded-tip scissors for safety- Making it a positive experience with treats and praise
Did you know some cats actually need "eyelash trims"? It sounds funny, but abnormally long lashes can constantly irritate the eye surface, leading to excessive tearing. Your groomer or vet can handle this delicate task.
When to Seek Professional Help
Red Flags That Warrant a Vet Visit
While most watery eye cases aren't emergencies, these signs mean you should schedule a vet appointment:- Squinting or keeping eye closed- Rubbing face excessively- Visible third eyelid- Cloudiness or color change in eye- Thick yellow/green discharge
Trust me, it's better to be safe than sorry when it comes to eye health. Early intervention often means simpler treatment and faster recovery.
What to Expect at the Vet
Your vet will likely:- Perform a thorough eye exam- Check for corneal scratches with special dye- Measure tear production- Examine eye pressure if needed- Possibly flush the tear ducts
Bring notes about when the watering started and any changes you've noticed. This helps your vet pinpoint the cause faster. And don't worry - most cats handle eye exams better than humans do!

FAQs
Q: Should I worry if my cat's eye waters occasionally?
A: Occasional watery eyes are usually nothing to stress about, especially if your cat is a flat-faced breed like a Persian. We see this all the time in our clinic. However, if the watering persists more than 24 hours, or if you notice redness, squinting, or your cat pawing at their eye, it's time for a vet visit. Think of it like this - would you ignore your own eye if it watered nonstop for a day? Some key warning signs include thick yellow/green discharge (that's the "ick" factor), cloudiness in the eye, or any behavior changes. When in doubt, snap a quick photo to show your vet - it really helps us assess the situation!
Q: Why does my cat only have one watery eye?
A: Single-eye watering happens more often than you'd think - about 60% of cases we see affect just one eye. The most common reasons include feline herpesvirus (which often starts in one eye), an abnormal eyelash rubbing the cornea, or a blocked tear duct on that side. I had a case last week where a cat named Whiskers came in with left-eye watering - turned out to be a tiny scratch from playing too rough with his brother. The takeaway? One-sided watering doesn't necessarily mean it's less serious, so don't ignore it if it persists.
Q: Are some cat breeds more prone to watery eyes?
A: Absolutely! Flat-faced breeds like Persians and Himalayans are basically walking tear factories due to their facial structure. Their shallow eye sockets and compressed tear ducts make proper drainage nearly impossible. In our practice, we joke that these breeds come with "built-in water features." The table in our article shows the likelihood by breed - but remember, even regular domestic shorthairs can develop watery eyes from infections or allergies. The key is knowing what's normal for YOUR cat.
Q: Can I use human eye drops for my cat's watery eyes?
A: Please don't! I can't stress this enough - human medications can be dangerous for cats. Their eyes are much more sensitive than ours. I once treated a cat who got severe corneal damage from well-meaning owners using Visine. Instead, we recommend plain saline solution for gentle flushing, or better yet, get vet-prescribed eye drops specifically formulated for cats. Pro tip: warming the drops to body temperature makes application much easier (test on your wrist first).
Q: How can I prevent my cat's eyes from watering?
A: Prevention depends on the cause, but here are my top 3 tips from years of practice: First, keep up with vaccinations - feline herpesvirus is a major watery eye culprit. Second, regularly clean your cat's face with vet-approved wipes (especially important for flat-faced breeds). Third, minimize stress - yes, anxious cats often develop eye issues! Simple changes like consistent routines and vertical spaces can work wonders. Remember, some cats will always have slightly watery eyes, and that's okay - it's part of their charm!
