: Small debris, seeds, or hair can physically plug the passage.
Cats produce tears to lubricate and clean their eyes. Normally, these tears drain through tiny openings (puncta) in the inner corners of the eyes, traveling down the nasolacrimal duct into the nose and throat. When that duct gets blocked, tears spill over the eyelid and down the face—a condition called epiphora.
The treatment of a blocked tear duct in cats depends on the underlying cause and severity of the condition. Treatment options may include:
The most visible sign is constant dampness on the face. Owners typically notice: Blocked Tear Ducts (Dacryocystitis) in Cats - Vetster blocked tear duct cat
epiphora (excessive tearing). Vetlexicon +1 Watery Eyes: Constant wetness in the corners of the eyes or beneath them. Tear Staining: Reddish-brown or dark discoloration of the fur along the path of the tears. Skin Irritation: Chronic moisture can cause redness, itching, hair loss, and "facial dermatitis". Odor: Foul-smelling bacteria may grow in the damp fur. Discharge: Blockages caused by infection (dacryocystitis) may produce milky, yellow, or green mucus. VCA Animal Hospitals +6 2.

Inflammation/Infection: Swelling from conjunctivitis or respiratory infections can pinch the duct shut. Physical Obstruction: Foreign material (e.g., grass seeds) or inflammatory debris can lodge in the duct. Hereditary Defects: Some cats are born without a "puncta" (the opening where the duct meets the eye). Dental Issues: Because the duct passes near tooth roots, abscesses or severe dental disease can compress it. Wiley Online Library +11 3. Diagnosis Veterinarians typically use the following methods to confirm a blockage: Fluorescein Dye Test: A yellow-green dye is placed in the eye. If the duct is clear, the dye should appear at the nose or mouth within 5–10 minutes. Duct Flushing: Under sedation, a veterinarian may insert a tiny tube (cannula) to flush saline through the duct to check for resistance. Imaging: X-rays with contrast dye (dacryocystorhinography), CT scans, or MRIs can identify tumors or structural abnormalities. VCA Animal Hospitals +3 4. Treatment Options Medical Management: If caused by inflammation, vets may prescribe antibiotic or anti-inflammatory eye drops. Manual Flushing: Sometimes the act of flushing with saline is enough to clear minor debris. Surgical Correction: Imperforate Puncta: Creating a surgical opening for the duct. Stenting: Placing a tiny tube to keep the duct open during healing. New Pathway: In severe cases, a new drainage route to the nose or mouth may be surgically created. MSD Veterinary Manual +7 5. Home Care & Prevention Daily Cleaning: Gently wipe the under-eye area with a warm, damp cloth to prevent tear staining and skin infections. Veterinary Monitoring: Seek a vet if discharge changes color, the eye appears painful (squinting), or the skin becomes raw. Vetericyn Animal Wellness +2 Is your cat showing other signs like
Diagnosing a blocked tear duct in cats typically involves a physical examination and a series of tests. Your veterinarian may perform the following:
If you’ve noticed your cat constantly has a wet, stained area below one or both eyes—almost like they’re silently crying—a blocked tear duct could be the reason. : Small debris, seeds, or hair can physically
Occasional tearing without redness or discomfort may just be a cosmetic issue. But if the eye looks red, swollen, or your cat is squinting or pawing at it, see a vet quickly—corneal ulcers or glaucoma can mimic a blocked duct and need urgent care.
: Some kittens are born without a proper opening to the tear duct. 🏥 Diagnosis & Treatment
As any cat owner knows, our feline friends are prone to a variety of health issues, including eye problems. One common condition that affects cats is a blocked tear duct, also known as nasolacrimal duct obstruction. This condition occurs when the tear duct, which is responsible for draining tears from the eye into the nasal cavity, becomes blocked. In this essay, we will discuss the causes, symptoms, and treatment options for blocked tear ducts in cats. When that duct gets blocked, tears spill over
With proper diagnosis, most cats with blocked tear ducts can be managed easily, keeping their eyes bright and comfortable.
A blocked tear duct (epiphora) in occurs when tears cannot drain through the nasolacrimal duct into the nose, causing them to spill over onto the face. While often a cosmetic issue, chronic blockages can lead to skin infections and irritation from moisture. 🛠️ Common Causes
In addition, regular monitoring and maintenance of your cat's eye health can help to prevent complications and improve treatment outcomes.
