Have Cat Questions? Ask a Cat Vet Online.
If your cat has green discharge from the eyes and nose, the problem is now bacterial (as opposed to viral) and you need to see the vet with her. They will not get over this on their own. They need antibiotics. I would also be very concerned about feline herpes which is common in cats.
So - step 1 - go ahead and see the vet with her.
Let me know if you still have questions.
