Who runs this
PetMathStudio is written and maintained by James Wu. Builds calculator-driven research sites for niche audiences. On PetMathStudio, runs source-first dog and cat calorie, weight, age, growth, toxicity, and pregnancy calculators — sourcing tier built on NRC, WSAVA, AAFCO, AAHA, and Cornell Vet.
What this site is for
PetMathStudiois for pet owners who want real numbers — not vibes — when they're working out how much food their dog actually needs, whether their cat is at a healthy weight, or what their puppy is going to weigh full-grown. Most pet calculators online are either ad-padded blogs with no sourcing, or clinical-grade tools designed for vets and veterinary students.
This site cites NRC, WSAVA, AAFCO, and AAHA directly, runs on the same math your vet uses, and shows the formulas — written for owners doing the math themselves. Predictive calcs (puppy adult size, dog age, weight projections) render as labeled ranges with visible assumptions, not single numbers, because that's how the underlying research actually works.
