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.
How Much to Feed a Senior Cat. Most senior cats will have about the same caloric needs as an adult cat— roughly 280 to 360 daily calories depending on the normal lean weight—as long as they are healthy. Some older cats will actually have an increase in energy requirements.
Becker, the most important thing in feeding senior cats is to provide them with the highest quality protein. Feeding a highly digestible protein that contains high moisture content makes it so much easier for their aging organs to process. Raw or “gently cooked” fresh food is an excellent diet for elderly cats.
Cats’ appetite changes as they grow older. For some felines this means a bigger appetite and looking for indulging treats more often. However, it’s best to make sure the vet rules out the medical conditions mentioned above before blaming the senior years for your cat’s newly-found love for food.
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.
Wet food is easier for many senior cats to manage and the increased moisture content is important for digestion and kidney health as well. If your cat insists on dry food, try using moisture-rich wet food as a topper.
Well-recognized causes of weight loss in old cats include chronic renal disease, diabetes mellitus, hyperthyroidism, inflammatory bowel disease (IBD), exocrine pancreatic insufficiency, and dental problems. Dental disease can contribute to weight loss in senior cats.
It is a metabolic disorder caused by an excess of thyroid hormone. It occurs most commonly in cats over the age of 8 years and is more common as cats get older. The classic sign is a cat that is more active and eating tons of food without gaining weight.
Some of the common causes of an increased appetite are: Worms: Worms, or intestinal parasites, feed off what your cat eats and steal most of the nutrition from their food. This means that cats eat and still feel hungry, as they’re getting very little of their diet’s nutritional value.
The natural changes that happen with aging can make a cat hungry all the time, too, Dr. Murphy says. As animals get older, their ability to digest fat and protein decreases while their energy requirements increase, she says, adding that in cats, the shift happens at around age 13.
If the cat owner is feeding a good quality dry food, that has a good quality protein, then the indoor cat needs only approximately 1/3 to 1/2 cup of food each day. Most high quality foods have approximately 500 calories per 8 ounce cup of food. The major protein source of the food is very important.
If the cat eats dry food, the correct dose of food is about 40 grams for each kilo of weight, and the total divided by three, because dry food is more concentrated than wet and to obtain the same requirement, a smaller amount is needed.
