We feed twice a day. Once around 7:30am when we eat breakfast and then again around 5-5:30om. She rarely eats right when we serve her and mostly just grazes throughout the day (based on what I observe on weekends). I like for her to have food available to eat when she feels like it. She’s always eager to eat a hard boiled egg or piece of treat, right when we offer it, though! I can’t imagine picking up the bowl in 15 minutes—seems so strict to me.
