How Much Should I Feed My Cat? Daily Portions Explained
Find out how much food your cat needs each day based on their weight, life stage, and diet type. Covers both wet and dry food portions with practical feeding guidance.
Key Technical Takeaways
- •A typical healthy adult cat needs between 200 and 300 kcal per day, depending on size and activity level.
- •Wet food is roughly 75–80% water and is highly beneficial for feline urinary and kidney health.
- •Most commercial cat foods list caloric density (kcal per cup or per pouch) on the packaging — this is the number you need for accurate portioning.
- •Cats do best with measured portions rather than free-feeding dry kibble, which commonly leads to weight gain.
- •Neutered indoor cats have lower calorie needs than intact or outdoor cats.
Getting your cat's daily food portions right is one of the most important things you can do for their long-term health. Too little food leads to nutritional deficiencies; too much leads to gradual weight gain, which is one of the most common health problems seen in domestic cats today.
Step 1: Know Your Cat's Daily Calorie Target
Cats, like all mammals, have a Resting Energy Requirement (RER) — the minimum number of calories needed to support basic organ function at rest. For cats, this is calculated as:
From this baseline, a life stage multiplier gives the total daily calorie target (Maintenance Energy Requirement, or MER):
| Cat Type | MER Multiplier | Typical Daily Target (4 kg cat) |
|---|---|---|
| Neutered indoor adult | 1.2 × RER | ~200 kcal/day |
| Intact adult | 1.4 × RER | ~230 kcal/day |
| Kitten under 6 months | 2.5 × RER | ~415 kcal/day |
| Weight loss target | 0.8 × RER | ~133 kcal/day |
| Pregnant queen (last trimester) | 1.6–2.0 × RER | ~260–330 kcal/day |
Step 2: Find the Caloric Density of Your Cat's Food
Check the bag, pouch, or tin for the Metabolizable Energy content, typically shown as:
- •Dry food: kcal per cup (typically 300–480 kcal/cup)
- •Wet food: kcal per 100g or per pouch/tin (typically 60–120 kcal/100g)
Step 3: Calculate Daily Portions
Dry food example:
- •4 kg neutered indoor cat, 200 kcal/day target
- •Dry food: 350 kcal/cup
- •Daily portion: 200 ÷ 350 = 0.57 cups per day (roughly half a cup, split into two meals)
Wet food example:
- •Same cat, wet food: 85 kcal per 85g pouch
- •Daily portion: 200 ÷ 85 = 2.35 pouches per day
Mixed diet:
If feeding both wet and dry food, apportion calories accordingly — for example, 50% from wet food and 50% from dry, dividing your daily kcal target between the two.
Wet Food vs. Dry Food: Which Is Better?
Both can form part of a complete diet, but they have distinct differences:
Wet Food Advantages:
- •High moisture content (75–80%) — excellent for hydration and kidney health
- •Generally more palatable for picky eaters
- •Lower caloric density (easier portion control for weight management)
- •Closer to a natural prey-based moisture level for cats
Dry Food Advantages:
- •More convenient and cost-effective
- •Longer shelf life once opened (use within a day)
- •Can support dental health if formulated for it
- •Higher caloric density (smaller volume needed)
Many vets recommend incorporating at least some wet food into adult cats' diets, particularly for urinary tract and kidney health.
How Often Should You Feed Your Cat?
Most adult cats do well with two measured meals per day (morning and evening). This is preferable to leaving food out all day (free-feeding), which makes portion control difficult and is a common contributor to feline obesity.
Kittens under 6 months old benefit from three or four smaller meals per day to support their rapid growth.
When to Consult a Vet
Book a check-up if your cat:
- •Has lost or gained noticeable weight without a change in feeding
- •Seems consistently hungry despite being fed appropriate portions
- •Has a known health condition like kidney disease, diabetes, or hyperthyroidism that affects nutritional needs
- •Is a kitten, pregnant queen, or nursing mother with higher specific nutritional requirements
