I have two kitten which are around 4 weeks old. I'm providinv them a kmr formula from last 6 days. Their poops are not looking fine to me. One of them's poop is greenish with a lot of liquid . Does it happen due to overfeeding. Because from last 3-4 days i was providing 50ml of milk 3 times a day to each of them . I'm providing poops pic here to make it easier to identify their problem.

Hello. At 4 weeks of age, you should be weaning these kittens onto a good kitten food. 50 ml of milk 3 times a day may just be too much for them, especially if the kittens are less than 1 pound. The other very big cause of diarrhea in kittens is intestinal parasites. I would bring a sample of the stool to your veterinarian & have it examined microscopically. If anything is seen, then the appropriate treatment can be started. Thanks for using Petco Pet Education Center, formerly Petcoach.
