A 5kg cat requires approximately 150g a day, or, 1050g over a week.
As a general guide, a small 4kg cat will require between 135-180 calories per day, which equates to around 130-205g of wet cat food, however, this will vary depending on the brand and type of food you choose.
To meet your cat's energy needs with wet and dry food, we recommend dividing the total feed by 3 and then feeding as follows: Give your cat 2/3 of the amount of food in the form of wet food and divide it into two rations (e.g. breakfast and dinner).
Most cats need 4-5 ounces of canned food per day, total. Pate-style varieties tend to be higher in calories per can than the varieties that more resemble people food with chunks and gravies- this can be useful when trying to fine-tune the number of calories per day being consumed.
In general, you can feed an average-sized adult cat one 3-ounce can per 3 to 3½ pounds of body weight daily. You should adjust this amount depending on whether you also feed your cat dry kibble. Your veterinarian may also recommend feeding more or less wet food depending on your cat's weight, health and other factors.
Example: Wet food
Cats weighing from 4 to 5kg should get between 265 and 310g per day.
How often should cats eat wet food? What do vets recommend? Wet food is not a special meal or an occasional treat. Cats can and should eat wet food every day because it agrees with the feline digestive system better than dry or semi-moist food.
For a 4 kg sterilized cat, which prefers to stay warm to sleep and has an energy requirement of about 200 kcal, a can of 85 g per day wet and a ration of 30 g of dry will be sufficient.
Feed 1 can per 3 to 3-1/2 pounds of body weight daily. Divide into 3 or more meals. Continue to adjust as needed to maintain your kitten in ideal body condition and avoid excess weight gain. Refrigerate unused portion.
The ideal weight of a cat can vary depending on the breed; however, for the majority of domestic cats, 10 pounds or 4 to 4.5 kg is considered a healthy weight. Larger domestic cat breeds are usually considered to be any cat that weighs over 11lbs or 5kg and some, like the Maine Coon, can weigh up to 25 pounds or 11kg.
So how much fluid should a cat drink every day? An adult cat needs between 50 ml and 70 ml fluid per kilo body weight every day.
A: 60 g in one cup of cat food. So, 5g is almost a tenth of a cup.
For a normal healthy 9 lb cat, the right amount of food is about a half cup of regular dry food (ballpark 350 kcal per cup).
Rule-of-Thumb Cat Calorie Calculator
A rule-of-thumb for calorie requirements for a normal adult cat is 20 to 33 calories per pound depending on their energy level. A 10-pound indoor cat should eat about 200 calories and an outdoor active cat can eat about 330 calories per day.
If you feed your cat wet food, one pouch per mealtime should be enough. If your cat doesn't eat the whole pouch, you could refrigerate it and when your cat is hungry again, gently warm the food back up in the microwave.
If your cat is hungry all the time, it could be a sign of a serious health issue like hyperthyroidism, diabetes or cancer. This handy guide looks at possible causes of overeating, symptoms to look out for and what to do if you're concerned about your cat's feeding habits.
As a general average, if you are feeding a commercially produced high-quality dry food with a good quality protein source, then an indoor cat would be fed about 1/3 to 1/2 cup of food per day. This amount of quality food is approximately between 167–250 calories.
Storing wet cat food
If you open a can of wet cat food and you only use half, keep the other half in the fridge and cover it securely. Specially designed can lids will keep them well sealed, but cling film works well too.
Canned food is more expensive per energy calorie than kibble due to the high water content and the packaging. Another disadvantage to canned cat food is that for some cats, canned food may contribute to periodontal disease.
The best way to tell whether your cat is eating enough is by monitoring their intake, tracking how much they're eating and leaving. Feeding your feline a high-quality diet – one that meets all their nutritional requirements – will not only keep them fighting fit, it should also stop them begging.
