How Much Should I Feed My Cat? The Complete Malaysian Feeding Guide
Share
The most common question at any cat nutrition consultation: "How much should I feed my cat?" The answer depends on your cat's weight, age, activity level, and the specific food's caloric density. Here's the complete guide — and why the "follow the bag" advice is often wrong.
Why Bag Feeding Guidelines Are Often Misleading
Pet food bags are required to include feeding guidelines, but these are almost always overestimates. Why? Because overfeeding leads to faster consumption, which leads to faster bag repurchase. The guidelines are also based on the average active adult cat — but most indoor Malaysian cats are less active than the model assumes, and many are desexed (which reduces metabolic rate by 20–30%). Use bag guidelines as a starting point, not a rule.
How to Calculate Your Cat's Daily Calorie Needs
Step 1: Find your cat's ideal weight
Feed to the weight your cat should be, not the weight they currently are. An overweight 6kg cat doesn't need 6kg-worth of calories — she needs calories appropriate for her ideal body weight of, say, 4.5kg.
Quick body condition scoring: Run your hands along your cat's ribcage. You should be able to feel individual ribs easily without pressing hard, with a thin layer of fat over them. If you can't feel the ribs, your cat is overweight. If the ribs are visibly prominent, she's underweight.
Step 2: Calculate resting energy requirement (RER)
RER (kcal/day) = 70 × (body weight in kg)^0.75
For a 4kg cat: 70 × (4)^0.75 = 70 × 2.83 = 198 kcal/day
Step 3: Apply a life-stage multiplier
| Life Stage / Status | Multiply RER by |
|---|---|
| Neutered adult, indoor | 1.2 |
| Intact adult, active | 1.4 |
| Kitten (under 4 months) | 3.0 |
| Kitten (4–12 months) | 2.0 |
| Pregnant (first half) | 1.6 |
| Pregnant (second half) / Nursing | 2.0–6.0 (increases with litter size) |
| Senior (7+ years), less active | 1.1–1.2 |
| Overweight — weight loss target | 0.8 × RER at ideal weight |
Example: 4kg neutered indoor cat → 198 × 1.2 = 238 kcal/day
Practical Feeding Amounts for Dry Food (Tera Diet)
Tera Diet's caloric density is approximately 360–380 kcal per 100g. Using the calculation above:
| Cat Weight | Daily kcal (neutered adult) | Tera Diet per day (approx) |
|---|---|---|
| 3kg | 190 kcal | ~50g |
| 4kg | 238 kcal | ~63g |
| 5kg | 283 kcal | ~74g |
| 6kg (target 5kg) | 265 kcal | ~70g (feed to ideal weight) |
Always check the specific food's caloric content on the bag or product page — these figures are estimates based on Tera Diet's formulation.
How Often Should You Feed?
Adult cats (1–7 years)
Two meals per day — morning and evening — is the most widely recommended feeding schedule for adult cats. It maintains steady blood glucose, prevents excessive hunger, and gives you two daily opportunities to monitor your cat's appetite (a drop in appetite is often the first sign of illness).
Kittens (under 6 months)
Three to four meals per day. Kittens have small stomachs and high energy needs — they need more frequent feeding to maintain blood glucose. From 6–12 months, transition to 3 meals, then 2 as they approach adulthood.
Senior cats (7+ years)
Two meals per day remains appropriate. For senior cats with kidney disease or hyperthyroidism, smaller, more frequent meals (3–4 per day) can improve food tolerance. Work with your vet on the right schedule.
Free feeding (leaving food out all day)
Not recommended for most cats. Free feeding is strongly associated with obesity, and most cats — particularly indoor desexed cats in Malaysia — will overeat when food is always available. Meal feeding gives you control over calories and early detection of appetite changes.
Signs You're Overfeeding or Underfeeding
| Sign | Overfeeding | Underfeeding |
|---|---|---|
| Body condition | Can't feel ribs; rounded belly | Ribs visible; spine prominent |
| Energy levels | Lethargic, sleeps excessively | Restless, crying for food constantly |
| Stool quality | Large, soft stools (excess undigested food) | Small, hard stools |
| Weight trend | Steady weight gain over months | Gradual weight loss |
Frequently Asked Questions
My cat always acts hungry. Am I underfeeding?
Not necessarily. Cats are hardwired to hunt multiple small meals throughout the day — even a well-fed cat may act hungry. Use body condition scoring (can you feel the ribs?) rather than your cat's behaviour to assess whether she's getting enough food. If body condition is healthy, ignore the hunger theatre.
Should I measure food every meal?
Yes — at least until you have an accurate feel for the right amount. Use a kitchen scale, not a cup. Dry kibble varies significantly in density, so volume measurements are unreliable. Even a 10g daily excess adds up to 3.6kg of extra weight per year for a small cat.
My cat lost weight after I switched to Tera Diet. Is that normal?
A small weight loss in the first 1–2 weeks after switching can occur as excess water retention resolves or if the new food is slightly less calorie-dense than the previous food. Weigh your cat weekly and adjust portions if needed. If weight loss continues beyond 3 weeks, consult your vet.
How much should I feed my cat if I'm mixing wet and dry?
Calculate total daily calorie target, then subtract the calories from wet food before calculating the dry food portion. For example: a cat needing 238 kcal/day who gets one 85g wet food pouch (typically 80–90 kcal) needs approximately 150 kcal from dry food — about 40g of Tera Diet.
