Kilo boy has been with me since the day he was born so to see his energy level drop through the year was hard. He's been eating THK food (Chicken whole grain) for almost a year and I can finally see some spark in him again. He loves it! And so do his brothers so now I'm switching everyone - never going back to dry food (or maybe emergency only kind, like humans have their hurricane kit foods) I use warm water to soak up as much moisture in the food as I can and it really fills him up. We tried the grain free previously but it seemed to leave him still a bit hungry.
