My breastfeeding cat has a sore eye. She is keeping it close

I'm sorry to hear this and understand your concern for Shera.

Does she have any sneezing, coughing or reduced appetite?

Any discharge from her eye?

Would a photo be possible please?

Thank you.

Thank you, ***** ***** just downloading these photos now.

Thank you.

I can see her 3rd eyelid is raised and she is squinting. There is a small amount of discharge which can be indicative of poor tear drainage or a bacterial infection.

The top consideration here would be a scratch from one of the small kittens which was done by mistake.

We'd also consider a viral infection, bacterial infection or foreign body under the eyelid (like some grit).

It is important she sees a vet who can stain the eye for any ulcers and flush it through.

She likely needs some topical antibiotics, which should not affect the kittens.

Try to prevent any rubbing and you can gently clean the eye with cotton wool and warm water.
