She got through the spay just fine, and is super tired. She's just getting plenty of peace and quiet right now. The vet said that it could be an abrasion of her lymphatic tissues, or it could have been caused by parasites (though they didn't find any during her spay). Or, this abnormality could just be "normal" for her body. We should have the results of the biopsy next week. I hope it's nothing major
