The Thing About Cats and Portion Sizes
Cats are obligate carnivores with a stomach roughly the size of a golf ball. That means two things — they need nutritionally dense food, and they need the right amount of it. Too little and they're not getting the fuel to thrive. Too much and the consequences build quietly, meal by meal, until a weight problem is already established.
This guide covers both kitten and adult cat wet cat food feeding requirements.
Why Wet Food Matters: What's Actually in That Tray or Pouch
Cats evolved consuming prey with a moisture content of around 70–75%. Wet cat food closely mirrors this, which is why it plays such an important role in keeping cats well hydrated — particularly cats who don't drink much water on their own.
Beyond hydration, wet food is highly palatable and easy to digest. For kittens, it's the ideal first format after weaning — soft enough for developing teeth and digestive systems, and nutritionally concentrated enough to fuel rapid growth. For adult cats, it contributes meaningfully to urinary tract health, weight management, and overall meal satisfaction.
ADVANCE™ wet cat food is formulated to be complete and balanced at every life stage, backed by Waltham Petcare Science Institute research, and made with high-quality ingredients. Whether you're feeding trays, pouches, or a combination of both alongside dry food, the principles in this guide apply.
Part 1: Kitten Wet Food Feeding Guide (From 8 Weeks to 40 Weeks)
Kittens are not small adult cats. They need up to three times the calories per kilogram of body weight that an adult cat requires, and those needs shift dramatically across their first 10 months of life. The ADVANCE™ kitten wet food feeding charts below cover both trays and pouches, so you can use whichever format you have on hand.
ADVANCE™ Kitten Wet Food: Trays Per Day
| Age of Kitten | Trays per day |
| 8 weeks | 2 |
| 12 weeks | 21⁄2 |
| 16 weeks | 31⁄2 |
| 24 weeks | 31⁄2 |
| 32 weeks | 31⁄2 |
| 40 weeks | 31⁄2 |
ADVANCE™ Kitten Wet Food: Pouches Per Day
| Age of Kitten | Pouches per day |
| 8 weeks | 3 |
| 12 weeks | 4 |
| 16 weeks | 41⁄2 |
| 24 weeks | 5 |
| 32 weeks | 5 |
| 40 weeks | 5 |
Mixing wet and dry kitten food? Halve the recommended daily quantity of each product. For example, if the guide says 4 pouches per day for a 12-week kitten, feed 2 pouches plus the equivalent half-portion of ADVANCE™ dry kitten food.
Why the Tray and Pouch Amounts Differ
You'll notice that the pouch guide calls for more serves per day than the tray guide. This is because trays and pouches differ in serve size — trays typically contain more food per unit than pouches. The total daily food intake is calibrated to the same nutritional needs; the number of serves simply reflects the format's weight/volume per unit.
If in doubt, check the serving size on the product packaging you're using and use the corresponding chart above.
What's Happening in Your Kitten's First 40 Weeks
The jump in portions from 8 weeks to 16 weeks reflects one of the most energy-intensive phases in any animal's life. At 8 weeks, a kitten has just been weaned — their digestive system is still adapting to solid food, and smaller amounts more frequently is the right approach. By 16 weeks, growth has accelerated dramatically, and energy requirements have nearly doubled to support bone density, muscle development, brain function, and a rapidly maturing immune system.
The plateau from 16 weeks to 40 weeks isn't stagnation — it reflects a phase where growth continues at a consistent rate rather than the explosive early surge. The amounts stay steady because your kitten's needs have stabilised into their peak growth maintenance phase.
How Often to Feed Your Kitten Per Day
Kittens stomachs are small, and regular meals prevent dips in blood sugar and keep energy levels consistent — important for both their wellbeing and their development.
8 weeks to 3 months: 4 meals per day. Meals should be spaced evenly — roughly every 4 hours during waking hours.
3 to 6 months: 3 meals per day. Growth is still rapid, and consistent fuel throughout the day supports it.
6 months onwards: 2 meals per day. Most kittens settle comfortably into a morning and evening rhythm at this stage and can continue this into adulthood.
A consistent schedule isn't just convenient — it helps establish healthy digestion, reduces anxiety around food, and makes it much easier to notice if your kitten's appetite changes unexpectedly.
Part 2: Adult Cat Wet Food Feeding Guide
Once your cat has transitioned to adulthood — typically between 9 and 12 months for most breeds — their nutritional needs shift from growth-focused to maintenance-focused. Adult feeding guides are structured by current body weight rather than age, because a healthy adult cat's daily food requirement is primarily driven by how much they weigh and how active they are.
ADVANCE™ Adult Cat Wet Food: Trays Per Day
| Weight of Cat | Trays per day |
| 3 kg | 21⁄2 |
| 4kg | 3 |
| 5 kg | 31⁄2 |
| 6 kg | 4 |
| 7 kg | 41⁄2 |
ADVANCE™ Adult Cat Wet Food: Pouches Per Day
| Weight of Cat | Pouches per day |
| 3 kg | 3 |
| 4kg | 31⁄2 |
| 5 kg | 4 |
| 6 kg+ | 5+ |
Feeding guidelines vary between products. The amounts shown here are a general guide only — refer to the packaging for the exact recommended daily amount for your dog's weight and life stage.
Mixing wet and dry adult food? Halve the recommended daily quantity of each. So if your 4 kg cat would receive 3 trays of wet food per day on wet alone, feed 11⁄2 trays plus the equivalent half-portion of ADVANCE™ dry adult food.
When Does a Kitten Become an Adult? Knowing When to Switch
The transition from kitten to adult food is one of the most important feeding decisions you'll make. Switch too early and your growing cat misses the elevated nutrition their development still requires. Switch too late and you're providing growth-formula energy to a cat whose growth phase is done.
For most domestic cats, the transition to adult food happens between 9 and 12 months. Larger breeds — such as Maine Coons or Ragdolls — may not reach full maturity until 15–18 months and may benefit from staying on kitten-formula food slightly longer. When in doubt, your vet is the best person to confirm timing for your individual cat.
When the time comes, transition gradually. Replace roughly 25% of the kitten food with adult food on day one, increasing the proportion over 7–10 days until the changeover is complete. Abrupt dietary changes can cause digestive upset — a slow transition gives your cat's gut microbiome time to adapt.
The Activity Factor: Adjusting Adult Portions for Your Cat's Lifestyle
The feeding charts above are calibrated for a typical adult cat at average activity levels. But indoor and outdoor cats can have meaningfully different energy needs, and desexed cats often require slightly less food than intact cats of the same weight.
Less active or indoor-only cats: Consider starting at the lower end of your cat's weight range and monitoring body condition over 2–3 weeks before adjusting further. Indoor cats who sleep most of the day burn noticeably fewer calories than cats with outdoor access.
Moderately active cats: The chart amounts are your baseline. These figures are built for cats with typical daily activity — some play, some movement, regular rest periods.
Very active or outdoor cats: You may need to increase portions modestly — around 10–15% above the chart amount. Monitor weight and coat condition weekly.
The most reliable guide isn't a number — it's your cat's body.
5 Signs Your Cat's Wet Food Portions Are Right
The charts give you the starting point. Your cat's body gives you the ongoing answer. Here's what well-nourished looks like:
Ribs that are felt but not seen. Run your fingers gently along your cat's sides — you should feel the ribs without needing to press hard, but they shouldn't be visually prominent. A layer of fat you have to dig through to find the ribs suggests overfeeding.
A visible waist. Looking down at your cat from above, there should be a clear narrowing between the rib cage and the hips. No visible waist is a common early indicator of weight gain.
Consistent, engaged energy. A well-fed cat is alert, playful when stimulated, and rests without seeming lethargic. Kittens especially should have sustained bursts of energy through the day.
A coat that shines. Dull, dry, or patchy coats can signal nutritional imbalance. ADVANCE™ wet food includes essential fatty acids specifically to support skin health and coat condition from the inside.
Leaving nothing behind — or not finishing at all. If your cat consistently eats everything and seems to want more, a modest portion increase may be warranted. If food is regularly left uneaten, reduce portions slightly rather than persisting with wastage.
The Hydration Bonus: Why Wet Food Helps More Than You Might Think
Cats have a naturally low thirst drive — an evolutionary hangover from their desert-dwelling ancestors who got most of their water from prey. This means cats fed exclusively on dry food often live in a state of mild chronic dehydration, which over time can place strain on the kidneys and urinary tract.
Wet cat food changes this equation significantly. At 75–80% moisture, a single tray or pouch of wet food contributes meaningfully to your cat's daily water intake in a way that a dry bowl of kibble simply cannot. For cats prone to urinary issues, or those who consistently drink very little, incorporating wet food into the daily routine isn't just about flavour variety — it's a practical contribution to long-term health.
This is as true for kittens building their urinary systems as it is for seniors managing existing health conditions.
Transitioning to ADVANCE™ Wet Cat Food: A 7-Day Guide
Whether you're switching brands, introducing wet food for the first time, or moving from kitten to adult formula, go gradually. A sudden change in diet — even to a higher-quality food — can cause digestive upset in cats, who tend to be even more sensitive to dietary change than dogs.
Days 1–2: Serve 75% current food, 25% ADVANCE™ wet food.
Days 3–4: Serve 50% current food, 50% ADVANCE™ wet food.
Days 5–6: Serve 25% current food, 75% ADVANCE™ wet food.
Day 7: Serve 100% ADVANCE™ wet food.
If your cat shows signs of digestive sensitivity — loose stools, reduced appetite, or vomiting — slow the pace and extend the transition to 14 days. Some cats are more cautious about new foods than others, and patience here pays off.
Also Feeding Dry Food?
Wet food and dry food work best as a team — and if your cat eats both, the dry side of the equation has its own science worth knowing. Did you know that the size of a cat's daily dry food portion needs to change the moment you add wet food to the mix? And that indoor cats often need noticeably less than the bag suggests? Get the full picture in the ADVANCE™ Dry Cat Food Feeding Guide, with complete daily portion charts by weight and life stage, plus everything you need to balance a mixed diet with confidence.
Frequently Asked Questions
How many pouches of wet cat food should I feed my cat per day?
For ADVANCE™ wet cat food, adult cats need 3 pouches per day at 3 kg, rising to 5+ pouches per day at 6 kg and above. Kittens need between 3 and 5 pouches per day depending on age, with the peak at 24 weeks and beyond. Always check the serving size on your specific product and use the charts above.
How many trays of wet cat food should I feed my adult cat per day?
For ADVANCE™ adult wet cat food, the daily tray guide starts at 21⁄2 trays for a 3 kg cat and increases to 41⁄2 trays for a 7 kg cat. Use your cat's current body weight to find the right daily amount.
How much wet food should I feed my kitten at 8 weeks?
At 8 weeks, ADVANCE™ kitten wet food guide recommends 2 trays per day (tray format) or 3 pouches per day (pouch format), divided across 3–4 small meals. This increases as your kitten grows — by 16 weeks they'll need 31⁄2 trays or 41⁄2 pouches per day.
Can I mix ADVANCE™ wet and dry cat food?
Yes — and a combination diet is recommended by most Australian vets for cats at all life stages. When mixing, simply halve the recommended daily amounts of both wet and dry food. The nutritional profile of each product is designed so that halving both delivers a complete and balanced daily intake.
When should I switch my kitten from kitten wet food to adult wet food?
Most cats are ready to transition between 9 and 12 months. Larger breeds may benefit from staying on kitten food until 15–18 months. When you make the switch, do it gradually over 7–10 days to avoid digestive upset.
How often should I feed my adult cat wet food per day?
Adult cats do well on 2 meals per day — morning and evening. Their daily wet food portion should be divided equally between both meals. Kittens under 6 months need 3–4 smaller meals per day.
Why does my cat seem hungry even after the correct portion?
Some cats eat quickly and appear to want more even when nutritional needs are met. If body condition is healthy, the portion is right — try dividing the daily amount into 3 smaller meals instead of 2 to extend meal satisfaction across the day. If your cat is genuinely losing weight on the chart amount, consult your vet to rule out any underlying health factors.
