The Cost of Feeding a Dog or Cat

In short

Feeding cost depends mostly on your pet's size and energy needs, the food's calorie density and type (dry, wet, fresh), and how many treats you add. A small cat costs far less to feed than a large dog. The most useful comparison is cost per day (calories your pet actually needs), not price per bag. This page explains the variables so you can budget — it does not name brands or prices.

What drives feeding cost

  • Body size and energy needs: a large, active dog eats far more than a small cat.
  • Food type: wet and fresh foods usually cost more per calorie than dry; raw and prescription diets add cost.
  • Calorie density: a more concentrated food means smaller portions, so price per bag can mislead.
  • Life stage and health: growth, pregnancy, or therapeutic diets can change needs and cost.
  • Treats and extras, which add up and should fit within the daily total.

How to compare and budget sensibly

A cheaper bag is not always cheaper to feed.

  • Work out cost per day from the calories your pet actually needs, not the bag price.
  • Use the feeding guide and your vet's input to estimate the daily amount.
  • Factor in treats, dental chews, and any supplements.
  • Remember that a complete-and-balanced food fed correctly is the goal, within your budget.
  • Our Pet Cost Calculator can help you map out ongoing costs.

Budgeting checklist

  • Estimate your pet's daily food amount from the label and vet guidance.
  • Calculate cost per day, not just price per bag.
  • Include treats and extras in the total.
  • Account for life-stage or health-related diet changes.
  • Revisit the budget as your pet grows or ages.

What not to assume

  • Do not assume the cheapest bag is the cheapest to feed — calorie density matters.
  • Do not assume the most expensive food is automatically best for your pet.
  • Do not forget treats and extras when budgeting.
  • Do not cut portions to save money without veterinary guidance.

When to ask a veterinarian

Nutrition is individual, and this page cannot assess your specific pet. Ask a licensed veterinarian — ideally before major changes — especially in these situations.

  • Puppies, kittens, pregnancy or nursing, or seniors — life stages with particular needs.
  • Weight concerns, a changing body condition, or any recommended weight-loss or weight-gain plan.
  • Any diagnosed condition or prescription diet (for example kidney, urinary, diabetic, or allergy diets).
  • Vomiting, diarrhoea, appetite loss, or refusal to eat that lasts or keeps coming back.
  • Before a major diet change, or if you are considering a raw, vegetarian, or home-prepared diet.

The Cost of Feeding a Dog or Cat — Frequently Asked Questions

Why is cost per day better than price per bag?
Because foods differ in calorie density: a pricier, more concentrated food may need smaller portions, making it cheaper to feed per day than a cheaper but less concentrated food. Comparing cost per day reflects what you actually spend feeding your pet.
Is feeding a cat cheaper than feeding a dog?
Usually yes, mainly because cats are much smaller and need fewer calories than most dogs. A large, active dog is typically the most expensive to feed, while a small cat is among the least.
Does FaunaHub recommend budget brands?
No. FaunaHub does not rank or recommend brands and carries no affiliate food links. We explain the factors behind cost so you can budget and choose with your veterinarian.
