Cat food cost
Cat food cost per month.
Cat food cost is easier to compare when price is normalized by calories. Price per pound helps with dry food, but price per 100 kcal is usually more useful across dry and wet formats.

| Food scenario | Typical use case | Estimated daily cost | Estimated monthly cost | Best metric |
|---|---|---|---|---|
| Budget dry food | Cost-focused adult cat plan | $1.05 | $32 | $/lb and $/100 kcal |
| Mixed wet and dry | Common blended routine | $1.58 | $48 | $/100 kcal |
| Mostly wet food | Higher-moisture feeding pattern | $2.89 | $88 | $/100 kcal and $/oz |
What this misses
This page compares cost, not medical suitability. Diet changes, prescription diets, and health concerns should be discussed with a veterinarian.
Monthly method
Why the calorie method gets closer to the real bill.
Cat food cost per month is not the same as bag price or can count. The useful number is what a daily feeding target costs over 30.44 days.
Start with total package calories. For dry food, the label may show kcal per cup or kcal per kilogram. For wet food, it may show kcal per can, tray, pouch, or serving. Convert that into total package kcal, divide the current price by that number, then multiply by your cat's daily target.
This keeps wet and dry comparisons from becoming misleading. A dry bag can look cheaper by weight while a wet case may look expensive by count; price per 100 kcal translates both into feeding cost.
Use this monthly page for the household estimate, then use the product calculator when you want to sort example rows by cost per 100 kcal. If a food is prescription, therapeutic, or tied to a medical plan, keep the diet decision with your veterinarian and use CatCost only for budget planning.
