Yes, if he is 5 to 6 weeks old, he doesn’t need KMR second step. I think this is an advertising ploy on their part to get you to buy more KMR. My opinion only here. You can get some goat’s milk and either mix it with his food, or give it to him in a saucer in addition to the wet food. It’s found in the refrigerated milk section of the grocery, or in the baking aisle in cans and powder. The canned is condensed, so add water 1 to 1. Whenever you change diet, it usually reflects in the poop. He probably has worms also, most kittens do, so when you take him back to the vet, they can give him some worming medication at that time. It doesn’t sound like it’s affecting him greatly, but if it should get worse, make sure to call the vet and ask for advice. You can also add a little canned pumpkin (pumpkin only no spices added) to his wet food to add fiber and help with the diarrhea.
