Hi! It's been roughly 15-20 days that Maggie has been shifted to protein rich diet from urinary s/o diet. Some part of her stool colour appears black. We've got her Fecal evaluation, liver function and B-12 tests which all seems to be normal (as explained by her doctor). Even today some part of it was still black and pale green along with the normal stool colour. She is active, eating well and stool consistency is normal. Should it still be concerning?
