How Many Cans of Wet Food for Cat? 7 Simple Ways to Keep Your Cat Healthy

Feeding the right amount of daily wet food for cats is essential for their health and hydration. Many cat owners struggle to determine the right amount of daily wet food for cats to keep their pets healthy.

How many cans of wet food should I feed my cat every day?

If you own a cat, you’ve probably asked this question at least once:

Some people say one can is enough. Others say three. The truth is, there’s no one fixed answer. Every cat is different, and feeding the right amount depends on a few important things.

Let’s break it down in a simple and practical way.

Why Wet Food Is Good for Cats

Cats don’t drink much water naturally. In the wild, they get most of their moisture from food. That’s why wet food is often a better option than dry food. When deciding how much daily wet food for cats to serve, always check the calories per can and your cat’s weight.

Wet food:

• Contains high moisture (around 70–80%)
• Helps prevent dehydration
• Supports kidney and urinary health
• Is easier to chew and digest
• Usually has more protein and fewer carbs

Because of these benefits, many vets recommend adding wet food to a cat’s daily diet. This guide will help you understand how much daily wet food for cats your pet needs based on age and activity. Feeding your cat the right amount of daily wet food for cats helps prevent dehydration and supports urinary health. According to the American Association of Feed Control Officials (AAFCO) standards, high-quality wet food provides essential nutrients for cats.

Don’t Count Cans — Count Calories

Here’s the most important thing most people don’t know:

Cats eat calories, not cans.

Different brands and flavors have different calorie amounts. One small can might have 70 calories, while another can have 180 calories.

So before deciding how many cans to feed, always check the calorie information on the label. When deciding how much daily wet food for cats to serve, always check the calories per can. The PetMD calorie calculator is a great tool to determine your cat’s daily needs.

How Many Calories Does a Cat Need Per Day?

On average:

• A healthy adult cat needs 200–250 calories per day
• Smaller or less active cats need 180–200 calories
• Very active or larger cats may need 250–300 calories

This is just a general guide, not a strict rule. Many cat owners prefer a combination of wet and dry food. The International Cat Care organization provides detailed guidance on the pros and cons of wet food for cats.

So, How Many Cans of Wet Food Is That?

Let’s assume you are using a standard 3 oz (85 g) can.

• If one can has 70–100 calories → feed 2.5 to 3.5 cans per day
• If one can has 120–150 calories → feed 1.5 to 2 cans per day
• If one can has 180+ calories → feed 1 to 1.5 cans per day

Always adjust based on your cat’s weight and activity level. Older cats may need softer food or smaller, frequent meals. The ASPCA Pet Care Resources offers helpful advice on feeding senior cats and maintaining their weight.

Feeding by Cat’s Age

Kittens (Up to 1 Year)

Kittens grow fast and need more food.

• 2–6 months:
  3–4 small meals per day
  Around 3–4 cans daily

  2–3 meals per day
  Around 2–3 cans daily

Never restrict food for kittens unless advised by a vet. Feeding your cat the right amount of daily wet food for cats is important for hydration and overall health. You can also check our guide on Best Dry Cat Food Options to learn how to balance wet and dry meals.
