Calculators
Precision nutrition made simple. Enter your pet's details and get a science-aligned daily feeding estimate — by weight, life stage, and activity level.
Why It Matters
Precision Feeding — Not Guesswork
Overfeeding and underfeeding are the two most common nutrition mistakes pet owners make. These calculators give you a science-based starting point — always refine with your vet.
Why Portion Matters
Even a 10% daily excess can lead to obesity within months in small animals. Consistent, weight-appropriate portions are the single most impactful feeding decision you can make.
Life Stage Nutrition
Puppies, adults, and seniors have fundamentally different caloric and nutrient needs. A one-size feeding approach is one of the most common — and avoidable — nutrition errors.
When to Adjust
Use body condition scoring monthly. If ribs are hard to feel, reduce by 10%. If they're too prominent, increase. A calculator gives you the start point — your pet's body tells the rest.
Dog Feeding Calculator
Estimates daily dry food intake based on weight, life stage, and activity level. Results are a starting guide — adjust based on body condition scoring.
Cat Feeding Calculator
Cats are obligate carnivores with unique caloric needs. This calculator accounts for lifestyle, weight, and diet type to estimate daily intake across wet and dry food.
Rabbit Feeding Calculator
Rabbits require unlimited hay as the dietary foundation. This calculator gives pellet and vegetable portions based on body weight.
Bird Feeding Calculator
Portion sizes vary significantly by species size. Select your bird type to get a daily pellet, seed and fresh food estimate.
Horse Feeding Calculator
Horse forage requirements are calculated as a percentage of bodyweight. Estimates daily hay and concentrate needs by weight and workload.
Reptile Feeding Guide
Select your species for a tailored feeding frequency and prey/food size guide.
Aquatics Feeding Guide
Overfeeding is the most common cause of poor water quality. Select your fish type for daily feeding frequency and portion guidance.
Feeding Tips
Four Rules Every Pet Owner Should Know
Calculators give you a starting point. These four principles help you refine from there.
Read the Label
Every food has a different caloric density. Always check kcal/kg or kcal/cup on the label — don't assume serving sizes from one brand apply to another.
Transition Slowly
Switch foods gradually over 7–10 days: 25% new / 75% old → 50/50 → 75% new → 100% new. Abrupt changes cause digestive upset in most species.
Monitor Body Condition
Weigh your pet monthly and use species-appropriate body condition scores. A healthy weight is the single best predictor of longevity across all species.
Consult Your Vet
Animals with medical conditions require individually tailored nutrition plans. Never rely on a calculator alone for a sick animal.

Always consult a licensed veterinarian or veterinary nutritionist before making significant dietary changes, particularly for animals with existing health conditions.
