Four days ago my rescue cat, Lyla, had to have an emergency c-section due to being too young and small to give birth naturally. Sadly none of the kittens survived. After staying at the vet for 3 days I brought her home yesterday evening. She is eating and drinking fine and doesn't have any behavioral differences from before the surgery, but today she has had an opaque pinkish discharge that has a bit of a metallic odor. From what I have real online discharge is normal after a c-section for about a week, but I haven't found anything describing color, consistency, or smell. If this normal or am I looking an an infection that needs to be treated?
