Free Pet Food Portion calculator with clear step-by-step results.
Splits a daily calorie target between wet and dry food by calories rather than by weight, which is essential because wet food is roughly a quarter the energy density of kibble. Feeding equal weights of both would deliver far fewer calories than intended.
Calorie split
Wet kcal = target x wet share; dry kcal = target - wet kcal
Grams required
Grams = kcal / (kcal per 100 g) x 100, for each food
General guidance only. Calorie targets and diet composition should be set with a veterinarian, especially for pets with kidney, urinary, diabetic or gastrointestinal conditions.
On the label as metabolisable energy, usually per 100 g or per can. If only per cup is given, weigh a cup - cup weights vary widely between kibble shapes.
Not inherently, provided total calories are controlled and both foods are complete. The common error is feeding a full portion of each rather than splitting the allowance.
