Calculators for dogs and cats

Seven tools, each with its source named. None of them makes up a number — where the published formula does not hold, it says so instead of guessing.

• How much food per day The daily portion in grams of a real food, not just calories — with the rule that picked it.
• Dog age in human years No “times seven” myth — the logarithmic epigenetic-clock relation (Wang et al., 2020).
• Cat age in human years On the AAHA / AAFP / International Cat Care chart, with the life stage.
• Ideal weight and BCS Not from a breed table but from ribs, waist and profile — the 9-point scale, step by step.
• Daily water intake The daily fluid need including what arrives in wet food — and when drinking is a reason to see a vet.
• Can we go out? Hot asphalt, heat risk and winter salt — a verdict from measured thresholds, not an invented surface temperature.
• What a pet costs per year Your own figures, added up by category — and the list of items people forget.
• Energy in pet foods The calories in 100 g of kibble, wet food, raw or treats — and the portion that follows.
