I have two new 5-6 week old rescue kittens. Both went to the vet the day I got them (4 days ago) and have been given deworming medicine. One of the kittens has been having lighter brown, liquid-y stool today. For the first three days I had been feeding them “cat milk” and wet food. Yesterday I started feeding them KMR step 2, as well as wet food. Is this something I should be worried about? She is acting perfectly normal, still playing, sleeping, and eating fine. I have posted a picture of the stool below (she pooped a lot more volume than this, she had just covered the majority of it already so it was not visible).
