my cat got into a fight and when he came in I could see the third eye lid.
it freaked me out I was crying like a little baby
I did a google search and a lot of them said bring him
to the vet and get it taken care of so you don't risk permanate damage/blindness .
I brought him the next day,they did the eye cream stuff and his eye looked bettter
within 2-3 days
I was about $200 for the visit/meds..
BUT I would have never forgiven myself if I waited for it to heal by itself and he ended up blind
Good luck! Hope your baby feel better soon.

Don't wait to long to see the vet if it does'nt heal on its own.
