About the Siamese
Vocal, athletic and intelligent — famously active and interactive. A typical adult Siamese weighs around 3–5 kg (Medium (slender)).
How many calories does a Siamese need?
Calorie needs use the veterinary formula 70 × weight(kg)0.75 (the Resting Energy Requirement), multiplied by a lifestyle factor of ×1.26 for a typical cat at the life stage shown. Enter your own animal's details in the calculator for an exact figure. The Siamese carries a breed metabolic adjustment of ×1.05, already applied below.

Feeding a Siamese for a healthy weight
Siamese cats are naturally slim, active and fast-metabolising; a lean, muscular build is normal. They stay healthiest with plenty of play and a measured diet.
What to feed a Siamese
Cats are true obligate carnivores: they require animal-derived protein, taurine, arachidonic acid and preformed vitamin A. Wet food is strongly recommended as a significant part of the diet because cats have a naturally low thirst drive and are prone to urinary and kidney problems on dry-only diets.
Two to four small meals a day mirrors a cat's natural grazing pattern better than one large meal. Puzzle feeders and timed feeders help indoor cats stay active and prevent begging.
Frequently asked questions
How much should I feed a Siamese cat?
A 4 kg Siamese needs roughly 190-230 kcal a day. Their sleek, active build is natural — feed to maintain that lean, muscular silhouette rather than trying to fill them out.
How much should I feed my cat per day?
A typical 4 kg neutered indoor cat needs about 200-240 kcal a day — roughly 55-65 g of dry food or around 200-230 g of wet pâté. Kittens and active cats need more; use the calculator for a weight-specific figure.
How much wet food should a cat eat daily?
If feeding wet only, a 4 kg cat needs roughly 200-230 g (about 2.5 standard 85 g pouches) of typical pâté per day. Mixed feeders should calculate total calories first, then split between wet and dry.
