Veterinarians can only evaluate nutrition when the diet history is specific. Bring: brand and exact formula names, dry vs wet proportions, measured daily amounts, treat types and counts, table food, and every supplement with dosing directions. Include recent changes in appetite, stool, water intake, and activity. This level of detail helps the veterinarian decide whether the plan needs a medical workup, a calorie adjustment, or a nutrient-density correction rather than another add-on.
Also note household context: multi-cat feeding competition, puzzle feeders, recent moves, new pets, or litter box changes. Stress can shift eating patterns and stool quality, making nutrition outcomes more variable. A clean timeline—what changed first, what changed next—often reveals that the “diet problem” began before the diet change, which is exactly the kind of clarity that shortens the path to a durable plan.
