🐾 Pets

Give your pets the best care with our veterinary-science-based calculators. The dog and cat food calculators use Resting Energy Requirement (RER) formulas and life-stage activity multipliers recommended by veterinary nutritionists to determine how much to feed your pet based on their weight, age, activity level, and food calorie density. The pet age calculator uses modern formulas that account for breed size in dogs and specific aging patterns in cats, going beyond the outdated 7-year rule.

Why This Matters

Overfeeding is the number one cause of pet obesity, which affects over 50% of dogs and cats in developed countries and leads to serious health problems including diabetes, joint disease, and shortened lifespan. Proper portion sizing based on your pet's specific characteristics can add years to their life. Our calculators help you find the right amount based on veterinary science, not just the generic guidelines printed on food packaging.
