Poor Baby! The swollen right eye could be due to an injury or an eye infection. The diarrhea could be due to intestinal worms, GI illness, a change in diet, eating something rotten, or a foreign body. Given the eye problem, she will need to see a vet first thing in the morning. Any eye problem needs to be checked out promptly, as leaving it untreated can lead to vision loss. Please take her into a vet first thing the morning, where the vet can treat her eye and the diarrhea. Best of luck.
