My duck Penelope is living indoors, at least for the cold weather. She has always gotten along with the cats just fine. One of them ignores her, the other actually really likes her, and the third cat has always been... weird and antisocial and spontaneously mean. Lately Penelope and her cat friend have been hanging out by the radiator - cat on the radiator and Penelope on the floor. Today I was in the living room watching TV and I heard a loud quack from the other room and those little slappy feet running away. I checked on her and didn't notice anything wrong until I went to change her diaper a few minutes later. Her right eye had a bloody tear coming from it and she wouldn't open it and I just know that the wrong cat was on the radiator and she got scratched.
(I always gave that cat the benefit of the doubt when nobody else would, but he is not on my nice list ATM.)
I put Penelope in the tub to rinse her eye and she is drinking and eating her favorite mealworms. She hardly ever opens the eye but when she does it looks much more normal than I was worried. Since it is Sunday I can't get her to a vet and I'm very worried about her eye. Does anybody know of something I can put on it to prevent infection or help it heal? We do have some human eye antibiotic creme, but I know that ducks can be very sensitive to certain antibiotics, especially ones that are made for humans. Is this just something that I have to keep an eye on (haha, no pun intended) and hope for the best?
Thank you so much for any input!
