CatFeedingCalc.com was created with a simple but important mission: to help cat owners, breeders, rescue organizations, and veterinary professionals calculate precise, science-based cat feeding portions using internationally recognized feline nutrition standards.
Every day, millions of cats are overfed or underfed because their owners rely on vague feeding guidelines on pet food packaging. These guidelines are often inaccurate and don't account for individual factors like neuter status, activity level, life stage, or health conditions. Our calculators change that by applying the same formulas used by veterinary nutritionists worldwide.
Our tools are designed for:
We've developed 9 specialized calculators, each tailored to a specific feline life stage or feeding scenario:
Calculate daily calories and food portions for adult cats based on weight, neuter status, and activity level using WSAVA RER/MER formulas.
Age-based feeding calculator for kittens 2-12 months, with growth calorie adjustments and meal frequency recommendations.
Low-metabolism calorie targets for cats 7+ years, with considerations for kidney health and joint support.
Extra nutrition calculator for pregnant queens (all trimesters) and lactating mothers with multi-kitten support.
Safe calorie deficit planner with BCS-linked feeding adjustments for gradual, healthy weight loss.
Convert equivalent calorie portions between dry kibble, canned wet food, and raw food diets.
Compare feeding requirements between large breeds (Maine Coon, Ragdoll) and small breeds (Siamese, Singapura).
Compare annual cat food costs across all 50 US states with 2026 sales tax rates and local tax considerations.
Project monthly and yearly cat food total consumption with budget estimates for single or multi-cat households.
All our calculators and recommendations are based on the most current, scientifically validated sources in feline nutrition:
We regularly review these sources for updates and revise our calculators accordingly. Our goal is to provide the most accurate, up-to-date feline nutrition calculations available online.
While we strive for maximum accuracy, we acknowledge that feline nutrition is both a science and an art. Individual cats may have unique needs that our calculators cannot fully account for. That's why we always recommend:
