Stela switched to two meals a day when she was 14 weeks old and she has been thriving and doing just fine. She is also not a great kibble eater and what works for her is a variety. Just add something yummy to her kibble every day, something different: a spoon of plain yogurt, cottage cheese, pumpkin( it's good to make the stool firmer), chicken, tuna....she will get curious about the new smell/taste and eat it. Works for me! good luck!
