Pet Nutrition by the Numbers: Energy Needs, Portions, Treat Budgets & Weight Plans

What you'll build

What you will be able to do

Each lab ends with a concrete result that you build yourself and the checker confirms, cell by cell.

• Calculate the resting energy need of six fictional pets from their body weight with POWER, compare it per kg and see why a dog five times heavier does not need five times the food.
• Look up an illustrative life-stage factor for each pet with XLOOKUP, turn resting energy into a daily energy need, total it for the club and see what a change of life stage does to the numbers.
• Turn each pet's daily energy need into grams and cups per day with the kcal values from fictional food labels, round the grams per meal to the kitchen scale and see how long a bag lasts.
• Split three cats' daily energy between wet pouches and dry food by a kcal share, turn both parts into pouches and grams, and work out how many pouches to buy for a month.
• Set a treat budget as a share of each pet's daily kcal, count the whole treats that fit, check the share really used and reduce the main meal so the day's total stays the same.
• Turn a vet's fictional weight plan for a dog into the first week's change, a 14-week projection with POWER, the number of weeks to the target and a line chart.
• Turn the new food label's 7-day switching schedule into grams of old and new food per day at the same kcal, total the new food used and check how much of the old bag is left.
• Compare three fictional dog foods by price per kg and per 1,000 kcal, cost Bruno's feeding per day and year, name the food that is really cheapest and chart the yearly cost.
