How This Calculator Works
Proper nutrition is vital for your cat's health and longevity. This calculator estimates daily calorie needs using the veterinary standard RER formula: RER = 70 x (weight in kg)^0.75, adjusted by a multiplier for age and activity. Indoor cats typically need fewer calories than outdoor cats due to lower activity levels.
Kittens require significantly more calories relative to their body weight because they are growing rapidly. Senior cats often need fewer calories as their activity decreases, but some seniors may need more if they have difficulty maintaining weight. Always consult your veterinarian for cats with special dietary needs.
The cups-per-day calculation depends on your specific cat food's calorie content. Check the label for kcal per cup. Wet food typically has fewer calories per serving than dry food. Many veterinarians recommend a combination of wet and dry food for optimal hydration and dental health.
Frequently Asked Questions
How many times a day should I feed my cat?
Most adult cats do well with 2 meals per day. Kittens should be fed 3-4 times daily. Some cats prefer grazing throughout the day, but measured portions help prevent obesity.
Should I feed wet or dry food?
Both have benefits. Wet food provides hydration and is often more palatable. Dry food is convenient and can help with dental health. Many vets recommend a combination of both.
How do I know if my cat is overweight?
You should be able to feel your cat's ribs with light pressure. From above, there should be a slight waist behind the ribs. If your cat's belly sags or you cannot feel the ribs, they may be overweight.
