Mixed feeding can be a good routine for many households. Wet food adds moisture and often feels more satisfying. Dry food is convenient and easy to portion. The hard part is the math.
Quick answer: choose a daily calorie target, subtract treats, then split the remaining calories across wet and dry food. A 70/30 split means 70 percent of food calories from wet food and 30 percent from dry food.
Why calories beat cans, cups and scoops
Wet food contains far more water than dry food. Cornell Feline Health Center notes that canned cat food has a moisture content of at least 75 percent, while dry food is much lower in water. That means a large-looking wet portion can still have fewer calories than a small-looking dry portion.
This is why BowlMath splits by calories first. Once the calories are assigned, it converts them into cans, grams or cups.
Example: a 70/30 wet and dry cat food split
Imagine your cat's food budget after treats is 220 kcal/day.
If the wet food is 95 kcal per can, that is about 1.62 cans per day. If the dry food is 380 kcal per cup, that is about 0.17 cups per day. If you know the gram weight per cup, BowlMath can also show grams.
When to use fixed wet first
Use fixed wet first when the wet food package is the real-world constraint. For example, maybe one pouch per day fits your budget and routine. Enter that fixed wet amount, then let BowlMath calculate the dry food that fits the remaining calories.
- Good for single-serve pouches.
- Good when your cat expects a certain wet meal.
- Good when you want less leftover opened wet food.
When to use fixed dry first
Use fixed dry first when your cat already gets a measured kibble amount, or when an automatic feeder dispenses dry food. Enter the fixed dry amount, then calculate the wet food that fits around it.
- Good for automatic feeders.
- Good for households where dry food is measured in grams.
- Good when wet food is the flexible part of the plan.
How many meals should the split become?
Cornell says adult cats can often be fed once or twice daily, while kittens usually need more frequent meals. Many owners still choose 2, 3 or 4 meals because it fits the cat and the household better. BowlMath breaks the daily result into those meal counts.
Is 70 percent wet and 30 percent dry best?
It is a useful default, not a rule. The best split depends on your cat's appetite, hydration, medical needs, body condition and the foods you use.
Can I mix wet and dry food in the same meal?
Many owners do, but portion the calories first. If your cat leaves mixed food uneaten, separate meals may be easier to track.
What if my dry food only says kcal/kg?
Enter kcal/kg and measure the dry food in grams. BowlMath converts kcal/kg into kcal per gram for the portion calculation.
If your cat is underweight, overweight, diabetic, on a therapeutic diet or eating poorly, ask your vet before changing portions.
