Pet tools
Free pet tools: convert pet age to human years, estimate monthly and yearly costs, and check cat or dog body condition (BCS). No sign-up, runs in your browser.
Calculate before deciding
These tools support quick pre-adoption checks: age conversion helps you understand life stage, cost estimation helps you reserve monthly budget and medical emergency funds, and body-condition scoring turns “too heavy or too thin” into a more objective BCS result. Tool results are educational only and should be combined with veterinary advice, local rules and the individual pet.
