Why Does Your Cat Have Heavy Tear Stains?

📝 Summary

Common causes of heavy cat tear stains, from ingrown lashes and blocked ducts to infections, ear mites, eye worms, cat flu, and a salty diet, with targeted fixes.

1 Structural and Physical Causes

Ingrown eyelashes rub the eye and keep it wet, so trim the surrounding fur regularly. Flat-faced breeds like Persians have short nasal passages that block tear drainage; clean the face daily with saline, encourage water intake, and keep the diet light. Dacryocystitis from a foreign object produces yellow-green discharge, eased by chloramphenicol drops and ointment for several days.

2 Infections and Parasites

Conjunctivitis or keratitis raise eye discharge; keep the eyes clean and use anti-inflammatory drops. Ear mites make a cat scratch, and the pain radiates to the eyes, so clean the ears routinely. Eye worms appear as white threads in the corner of the eye and call for regular deworming, internally every three months and externally monthly. Feline herpesvirus (cat flu) floods the eyes with discharge; acyclovir drops help mild cases, while severe cases need a vet.

3 Dietary Causes

High salt and low water intake, an unsuitable food, or oily kibble all worsen tear stains. Switch foods gradually over seven days to reduce stress, avoid salty meals, and choose a low-salt, low-oil staple. Use stainless steel, ceramic, or glass bowls to keep the face cleaner.
