What do you feed them?
Choose from our food database or enter the calorie number from your bag or can label.
How this works for aquatic pets: We use a percentage-of-body-weight method — no calorie counting needed. Just tell us the food type and number of animals.
For a whole tank, enter the total number of fish. We'll divide the daily portion.
These are typical average values. Use "Enter from label" to match your exact product.
Look for "Calorie Content" or "Metabolizable Energy (ME)" — usually near the ingredients list on the back or side of the bag or can. It reads something like "3,500 kcal/kg" or "350 kcal/cup". Match the toggle above to whichever unit your label shows. Can't find it? Use the list option — it's accurate enough for most foods.
We'll subtract this from the daily food portion.

Feeding a Russian Blue for a healthy weight
Russian Blues are known for being food-motivated and prone to overeating if free-fed, despite a naturally elegant build. Scheduled, measured meals suit them better than a full bowl.
What to feed a Russian Blue
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 Russian Blue?
A 4.5 kg Russian Blue needs roughly 200-240 kcal a day. They can be surprisingly food-driven, so measured meals rather than free-feeding help keep their elegant frame.
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.
