What to do now
Eye discharge can come from irritation, infection, or painful eye disease; squinting and cloudiness need prompt care.
Monitor
- Track which eye, discharge color, squinting, redness, swelling, and pawing.
- Watch appetite, sneezing, breathing, and energy.
- Prevent rubbing if possible and avoid touching the eye.
Call a vet
- Call today for squinting, colored discharge, swelling, or obvious discomfort.
- Call sooner if the eye looks cloudy or the cat keeps it closed.
- Ask whether same-day eye evaluation is needed.
Emergency now
- Use emergency care for eye trauma, sudden cloudiness, severe pain, or the eye held closed.
- Use emergency care if eye signs pair with trouble breathing or collapse.
- Do not use human eye drops unless directed.
Red flags
- Eye held closed or severe squinting
- Cloudy eye or visible injury
- Severe swelling or pain
- Trouble breathing or collapse with eye signs
