## The short answer

**Budget from the daily ration, not the price of one box.** Our dated UK examples cost £12.38 for 30 days of dry food at 60g/day, or £33.75–£45 for 30 days of wet food at three to four pouches/day. They are price illustrations for specific adult foods, not a national average or a diet ranking.

If your adult cat already eats and tolerates Felix Favourites in Jelly, the 40-pouch box is a useful pack to compare: it divides neatly into ten days at four pouches daily. [Check the 40 × 85g pack on Amazon](https://www.amazon.co.uk/dp/B0DPJBSQJY?tag=catstandard-21&ref=catstandard.co.uk). Compare its current delivered price with the £15 Tesco reference below; retailer prices differ.

## Cat food cost per month: real pack-price examples

All reference prices below are Tesco regular prices checked on 11 October 2026\. No loyalty offer, subscription saving or delivery charge is included. The wet-food calculation uses the manufacturer’s three-to-four-pouch adult reference; the dry example uses 60g at the 4kg boundary of its feeding table. Both manufacturers say needs vary. Use the label and your cat’s care advice for the actual ration.

Prices: [Tesco’s exact 800g dry-food pack](https://www.tesco.com/shop/en-GB/products/257972929?ref=catstandard.co.uk) and [Tesco’s exact 40-pouch wet-food pack](https://www.tesco.com/shop/en-GB/products/318266803?ref=catstandard.co.uk). Ration references: [Purina ONE manufacturer guide](https://www.purina.co.uk/cat/cat-food/product-purina-one-dry-chicken?ref=catstandard.co.uk) and [Felix manufacturer guide](https://www.purina.co.uk/cat/cat-food/product-felix-as-good-as-it-looks-favourites-selection-in-jelly?ref=catstandard.co.uk). Adult-food examples do not cover kittens or prescribed diets. Do not serve both full example rations together.

The difference is large because the products and amounts differ. A low bill is useful only if the food is appropriate and gets eaten. Your cat will not read the spreadsheet and graciously accept the cheapest row.

## How to calculate your own daily and monthly cost

For dry food: **pack price ÷ pack weight in grams × grams used per day**. Multiply the result by 30 for a 30-day comparison or by 365 for a full-year allowance. Divide the annual figure by 12 when adding it to a monthly household plan.

For pouches: **box price ÷ number of pouches × pouches used per day**. A £15 box of 40 works out at 37.5p a pouch. Four a day uses £1.50 of food daily. That gives £45 for 30 days, but £45.63 per average calendar month over a 365-day year. Twelve 30-day months miss five days; the cat is unlikely to volunteer for those.

If your cat has a mixed diet, calculate the actual wet portion and actual dry portion separately, then add them. Use the mixed-feeding instructions rather than combining two full daily allowances. Treats and food used in games also need to come from the appropriate overall ration.

## Food used is different from cash spent at the till

At 60g a day, 30 days uses 1,800g of dry food. That is £12.38 worth at the reference unit price, but starting with an empty cupboard requires three 800g bags: **£16.50 paid, with 600g left**. The next month starts with that stock.

At four pouches a day, 30 days needs exactly three 40-pouch boxes: **£45 paid**. At three a day, you need 90 pouches: buy three boxes for £45, use £33.75 worth and carry 30 pouches forward. Stock bought ahead is still money spent, even when its consumption belongs to next month.

Starting from no food in stock: 30-day shopping cash

__Starting from no food in stock: 30-day shopping cash__
| Scenario              | Whole packs needed | Cash at reference price | Unopened or usable remainder |
| --------------------- | ------------------ | ----------------------- | ---------------------------- |
| 60g dry food per day  | 3 × 800g           | £16.50                  | 600g                         |
| 3 wet pouches per day | 3 × 40 pouches     | £45                     | 30 pouches                   |
| 4 wet pouches per day | 3 × 40 pouches     | £45                     | No remainder                 |

## When is a bigger pack worth buying?

**Keep the food that works, then compare its pack sizes.** Divide the full delivered price by usable grams or pouch count. Check you are comparing the same adult recipe and pouch weight; an 85g pouch and a 100g pouch are different quantities.

For an established Felix eater, the 40 × 85g Favourites in Jelly pack on Amazon is the verified comparison route here. Our calculations use Tesco’s dated price, so recalculate with the offer you actually choose. We are not claiming Amazon is always cheapest.

Start with a smaller purchase when the food is unfamiliar. Bulk is sensible once you know it will be eaten and you can store it properly. A recurring delivery can help, but check the ongoing price and timing: six weeks of food arriving every four weeks is mainly a cupboard-management project.

### Check before buying

Confirm adult/kitten or prescribed-diet suitability, exact recipe, pack count and weight, expiry, storage instructions and full delivered price. Follow the food’s feeding guidance and individual veterinary advice where needed; do not switch an established diet solely to reproduce our cheapest example.

## Allow for food waste and storage

Weigh what you actually serve and record what you discard over a week. If half a pouch routinely goes uneaten, the budget needs to reflect that use rather than assuming every gram is consumed. Adjust routines appropriately, rather than leaving food out indefinitely to make the figures work.

Follow the exact pack’s instructions after opening. Keep dry food cool and dry and protect the original packaging information. Check the label’s opened-wet-food storage advice before buying several days’ food ahead. [Our food-waste guide](https://www.catstandard.co.uk/how-to-reduce-cat-food-waste/) helps with portions, freshness and ordinary feeding routines.

## Add food to the whole cat budget

Food is one recurring row. Add [monthly litter use](https://www.catstandard.co.uk/cat-litter-cost-per-month/), care, insurance and replacements, then annual bills and initial costs separately. [Our UK cat-costs guide](https://www.catstandard.co.uk/cat-costs-uk/) includes an itemised example, private calculator and printable worksheet.

For a new arrival, ask what food the cat already eats before assembling a large order. Use [the first-cat checklist](https://www.catstandard.co.uk/first-cat-essentials/) for the rest of the setup. Feeding devices are optional: a food budget does not require a fountain or automatic feeder.

## Sources and method

Retailer prices and manufacturer ration references checked 11 October 2026\. Calculations use the exact packs above, consumption rather than purchase frequency, 30 days for comparison and 365 for annual totals, rounded only at the displayed result. Amazon pack identity was separately verified; its current price is not substituted for Tesco’s reference. This researched guide makes no claim to nutritional superiority or owner testing.
