5-6 times is normal, plz follow the guidelines on the packet if u wanna know the exact amount of feed to be given. Divide that amount equally into 4-5 portions and give to your kitten every 3-4  hrs

5 to 6 times pooping with normal consistency stool is normal. If the stool is in abnormal color and consistency then it needs to be checked

It is ok if the poop consistency is fine. This frequency will decrease as age advances. However, whatever feed you are using make sure you adhere to the guidelines on the package and do not exceed the quantity. Kittens have a small stomach capacity. So ensure that you feed him small meals throughout the day rather than two large meals.
