What to Know
A small but genuinely useful category for pet owners: Pet Food Portion (recently corrected to use separate dog and cat energy-requirement multipliers, since the two species' needs genuinely differ) and Dog Walk Calories cover day-to-day care, while Pet Lifetime Cost and Pet Insurance Cost-Benefit help with the bigger financial picture of pet ownership.
Aquarium Stocking and Puppy Weight Predictor round out the set — the latter is explicitly caveated as a rule-of-thumb estimate, not a breed-specific growth prediction, since real growth varies enormously between breeds.
- Pet AgeConvert your dog's or cat's age into human-year equivalent using the published veterinary age charts.
- Aquarium Volume & Fish StockingCalculate your aquarium’s water volume in gallons and liters, and check a beginner fish-stocking guideline.
- Lifetime Cost of Pet OwnershipEstimate the total cost of owning a pet over its expected lifetime.
- Pet Insurance Cost-BenefitFind the break-even point on your pet insurance quote — how much in vet bills you'd need in a year before the policy actually pays off.
- Dog/Cat Daily Food PortionEstimate your dog or cat’s daily calorie needs based on species, weight, and activity level.
- Puppy Weight PredictorEstimate your puppy’s likely adult weight from its current age and weight using a commonly-cited rule of thumb.
- Dog Walk CaloriesEstimate how many calories your dog burns during a walk, based on weight, duration, and pace.
- Litter Box CostEstimate your monthly and yearly cat litter cost from bag size, price, and how often you change it.
