Blocked Tear Duct Cat -

First, never use human eye drops or try to flush the duct yourself. A vet will perform a simple fluorescein dye test—green dye dripped into the eye. If it doesn’t appear at the nose within a few minutes, the duct is likely blocked. They may also flush the duct with saline under sedation.

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. blocked tear duct cat
