Senior Cat Nutrition Guide & Worksheet

This guide provides general ranges. Cats are obligate carnivores and need high-quality animal protein plus plenty of moisture. Always consult your veterinarian for dietary recommendations specific to your cat's health conditions.

1 Daily Calorie Requirements by Weight

Body Weight Weight Range Less Active Senior Moderately Active Active Senior
Petite Under 7 lbs 110 – 140 cal 130 – 160 cal 150 – 180 cal
Average 7 – 11 lbs 140 – 200 cal 160 – 230 cal 180 – 260 cal
Large 11 – 15 lbs 200 – 260 cal 230 – 290 cal 260 – 320 cal
Extra Large Over 15 lbs 260 – 320 cal 290 – 360 cal 320 – 400 cal

A rough rule of thumb is about 20 kcal per pound of healthy body weight per day. Overweight or underweight seniors need a vet-guided plan, not these averages.

2 Recommended Nutrient Ranges

Nutrient Wet / Canned Dry / Kibble Why It Matters
Protein 40 – 50% 35 – 45% Obligate carnivores need ample animal protein to hold muscle
Fat 18 – 30% 15 – 22% Concentrated calories help underweight seniors
Carbohydrate Under 10% Under 25% Lower carbs suit diabetic and weight-prone cats
Moisture 70 – 80% 8 – 12% Wet food supports hydration and kidney health

Percentages are on a dry-matter basis except moisture. Wet food is generally preferred for seniors because the added water supports hydration and the kidneys. Consult your vet for specific recommendations.

4 Therapeutic Diets for Common Senior Conditions

Condition Diet Goal Key Features Notes
Kidney / Renal Disease Reduce kidney workload Restricted phosphorus, controlled high-quality protein Wet renal diets help with hydration; very common in seniors
Hyperthyroidism Manage thyroid hormone Limited iodine (e.g. Hill's y/d) Must be fed exclusively; no other food or treats
Diabetes Stabilize blood sugar Low-carbohydrate, high-protein, often canned Pair with consistent feeding times and vet monitoring
Weight Management Safe weight loss Controlled calories, higher protein to spare muscle Never crash-diet a cat; risk of fatty liver
Urinary / Bladder Reduce crystal risk Controlled minerals, increased moisture Wet food and water intake are protective
Dental Disease Comfortable eating Softened or wet food, warmed to release aroma Painful mouths reduce appetite; address dental care
Gastrointestinal Ease digestion Highly digestible, sometimes novel protein Helpful for chronic vomiting or loose stool
