For those unsure about choosing cat food. This guide covers complete and balanced nutrition standards, differences between dry and wet food, the unique nutritional needs of kittens, adult cats, and senior cats, the pros and cons of grain-free diets, and how to handle poor appetite.
When it comes to maintaining your cat's health, choosing the right food every day is one of the most important management tasks. Cats are "obligate carnivores," requiring their own unique set of nutrients that differ from dogs or humans. With countless food options available on the market, understanding "what criteria to use when selecting" directly impacts your cat's longevity and well-being.

Complete and Balanced Nutrition Food (AAFCO Standards)
When a cat food package displays "complete and balanced nutrition," it means that food and water alone provide all the nutrients your cat needs.
Japan's Pet Food Association adopts the component standards set by AAFCO (Association of American Feed Control Officials). Complete and balanced foods contain all approximately 40 nutrients cats require, including protein, fat, vitamins, minerals, and taurine in appropriate amounts.
Foods labeled as "general food" or "treats," on the other hand, are supplementary and lack nutritional completeness on their own. Always choose "complete and balanced nutrition" foods as your cat's main diet. Treats should comprise no more than 10% of your cat's daily caloric intake.
Reading Ingredient Labels
Ingredients are listed on the package in order of weight. Since cats are carnivores, foods with specific animal protein sources like "chicken," "salmon," or "turkey" listed first are ideal. Vague terms like "meat meal" or "poultry by-products" have unclear quality, so choose foods with specific ingredient names when possible.
Using Dry and Wet Foods Effectively
Dry Food (Kibble)
Moisture content: 10% or less
Advantages: Easy to store (about one month after opening), economical, provides some tartar control, good for free-feeding
Disadvantages: Cats may drink less water, increasing risk of urinary tract disease
When feeding only dry food, it's especially important to ensure fresh water is always available. To encourage water intake, place water bowls in multiple locations, or use an automatic water fountain for cats that prefer running water.
Wet Food (Canned and Pouch)
Moisture content: 70-80%
Advantages: Naturally increases water intake, high palatability, helps prevent urinary tract disease, recommended for cats with kidney disease
Disadvantages: Must be refrigerated and consumed within 24 hours of opening, more expensive, promotes tartar buildup
Combination Feeding
Many veterinarians recommend mixed feeding, using dry food as the main diet with wet food as a topping or supplement. For example, feeding dry food in the morning and wet food in the evening increases water intake while balancing cost and management.
Nutritional Needs by Life Stage
Stage
Characteristics
Food Selection Tips
Feeding Frequency
Kitten (up to 1 year)
Rapid growth
High protein, high calorie kitten formula
3-4 times daily
Adult (1-7 years)
Maintenance
Calorie control focus
2 times daily
Senior (7+ years)
Declining function
Easy to digest, kidney-considerate
2-3 times daily
Kittens (Up to 1 Year)
Growing kittens need more energy, protein, and calcium than adults. Choose foods labeled "kitten formula" or "all life stages." Split daily portions into 3-4 meals to prevent hypoglycemia. Weaning begins around 4 weeks of age, and by 8 weeks, kittens can eat dry food.
Adult Cats (1-7 Years)
"Adult cat" foods are appropriate. Adjust portion sizes based on weight and activity level, focusing on obesity prevention. Indoor cats are less active and gain weight easily, making "indoor cat" formula a good choice. For a 4kg adult cat, daily caloric needs are roughly 200-250 kcal.
Senior Cats (7+ Years)
Digestion and kidney function decline, making easily digestible, high-quality protein essential along with reduced phosphorus and sodium. Consider transitioning to "senior formula" around 7-8 years of age. Prescription diet from a veterinarian is necessary if kidney disease develops. Since appetite often declines, increasing the proportion of wet food is effective.
The Grain-Free Debate
Grain-free foods have become more common, but grains aren't necessarily harmful to cats. Cats can digest grains to some degree. What matters more than grain content is overall nutritional balance and ingredient quality.
The FDA investigated a potential link between some grain-free dog foods and dilated cardiomyopathy (DCM) in dogs, but no clear issues have been reported in cats. If you suspect grain allergies, it's worth trying grain-free food under veterinary guidance, but understand that "grain-free" doesn't necessarily mean "higher quality."
Addressing Poor Appetite
Warm it up: Warming wet food to body temperature (around 37°C) releases aromas and improves palatability
Switch foods: Long-term repetition can lead to boredom. However, abrupt changes cause diarrhea, so transition gradually over 7-10 days
Check for stress: Environmental changes, friction with other cats, or illness can trigger appetite loss
Change the dish: Some cats prefer shallow bowls that don't press against their whiskers (whisker fatigue prevention)
Split into multiple meals: Reducing portion size while increasing frequency may help
If your cat hasn't eaten anything for more than 24 hours, there's a risk of hepatic lipidosis (fatty liver), so consult your veterinarian immediately. Fasting is especially dangerous for overweight cats.
Food Storage and Freshness Management
Food quality depends heavily on storage methods. Dry food especially undergoes oxidation after opening, losing not just flavor but nutritional value as well.
Dry food: Transfer opened bags to airtight containers and store in a cool, dark place. Use within one month for best quality. Large bags offer better value but lose freshness faster—1-1.5kg bags are recommended for single-cat households
Wet food: Transfer to another container, refrigerate, and consume within 24 hours. Discard anything left at room temperature for more than 30 minutes
Freezing: You can freeze wet food in portions. Thaw in the refrigerator naturally; avoid microwaves due to uneven heating
Beyond diet management, oral care is also essential for health. For information on preventing tartar and gum disease in cats, see Complete Guide to Dog Dental Care (which covers common oral care principles for both dogs and cats).
Shop with Confidence on Brochoku
Preparing your cat's diet should begin before bringing them home. Brochoku lets you purchase kittens directly from cat-specialist breeders and confirm in advance what food they're currently eating and feeding amounts. After bringing your kitten home, transition to new food gradually over 1-2 weeks rather than abruptly. Consider purchasing your cat from Brochoku to ensure you bring home a healthy kitten in optimal condition.
