Pet Food Transition Planner

A food switch should hold your pet’s daily energy constant while the mix shifts. The planner takes the pet’s daily kcal target (RER/MER, including scenario adjustments), splits it by the schedule percentage, then converts each day’s split into grams on each food’s own energy density — so the two columns always add up to the same calories.

1. 1

   Step 1

   Species, breed, weight and life stage set the daily energy target

2. 2

   Step 2

   Pick the old and the new food — each food’s kcal-per-cup and grams-per-cup set its own density

3. 3

   Step 3

   Choose the schedule: the standard 7-day switch, or the 10-day one for sensitive stomachs

4. 4

   Step 4

   Follow the day rows — each day lists the exact grams of old and new food to serve

• 1

  Measure each day’s two portions in grams on a kitchen scale — cups hide big errors

• 2

  Serve the two foods mixed in one bowl unless your pet sorts them out

• 3

  Keep water freely available; a food change shifts thirst too

• 4

  Buy the new food in a small bag first so a refusal doesn’t strand a big one

• 5

  Write the day number on the food container so the household stays in sync

• Switching everything in a single day

• Mixing by volume (scoops) instead of energy-matched grams

• Treating one finished 7-day plan as proof of tolerance for the next food

• Changing food and treats at the same time, which hides the cause of any upset
