2.Cleaning method:Use pet-specific wipes or saline to gently wipe around the eyes, paying attention to cleaning from the inner corners of the eyes outward to avoid lint residue.
3.Indications for medical treatment:It is recommended to seek medical attention immediately when the following conditions occur:
| yellow/green discharge | Lasts more than 24 hours |
| Eyes obviously red and swollen | Loss of appetite accompanied by tearing |
4. Preventive measures
• Trim the hair around the eyes regularly (especially for long-haired cats)
• Keep the environment clean and reduce dust
• Avoid using irritating aromatherapy products
• Provide high-quality staple foods to reduce the risk of allergies
5. Special reminder from experts
Professor Li from the School of Veterinary Medicine at China Agricultural University pointed out in a recent live broadcast: "Persian cats, Garfield cats and other flat-faced breeds have special facial structures, so tearing is more common. However, if the amount of tearing suddenly increases or the color is abnormal, you still need to be alert to pathological factors." He also emphasized that the "human eye drops to treat cat tearing" circulated on the Internet have safety risks, and you must follow the doctor's advice.
From the above analysis, it can be seen that cats’ tears may be a normal physiological phenomenon or a disease signal. Owners should make scientific judgments based on specific manifestations to avoid excessive anxiety or delay in treatment. It is recommended to conduct regular eye health examinations for cats to prevent problems before they occur.
