Koko may have intestinal parasites still or colitis. She may have some food indiscretion or sensitivity. I suggest you take a fresh stool sample to your vet for a fecal exam. If she has parasites, she will need to be wormed/receive medication against the type of parasites present, again. sometimes worming has to be repeated. If she has a food indiscretion you will have to change her diet. Best to take her for a recheck to your veterinarian and discuss diet options with him.

    Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Lexi! At a minimum I would take a stool sample to your Vet. Causes of diarrhea in young animals are: intestinal parasites, viral or bacterial infections, food allergies/intolerance, tritrichomonas, intestinal diseases like IBD, pancreatitis. Kittens do need to be dewormed a few times and start their vaccines around 7-8 weeks. You can try changing her brand of kitten food and start a probiotic like Purina Fortiflora. But if she has yet to be dewormed or see a vet it is time to do so. I wish Lexi the best!
