Recently found a stray and took her to the vet. She had worms and diarrhea, I guess caused by the worms and her anus was really sore and it looked really bad. Vet gave me some medicine for her to intake 2 times a day for 7 days. Her poop looks a bit more solid but her anus looks a little watery and pink. Is this normal for my cat to be healing this way?
