I will develop a pet age calculator widget in human years

I'm developing a turnkey pet age calculator widget in human years — a small interactive tool that visitors to a veterinary clinic or pet store website open for entertainment and then return to again. Instead of the outdated rule "multiply by seven," I use an approach that accounts for the type of animal, breed size, and the fact that the first year or two of a pet's life, it "matures" much faster than in adulthood. The visitor selects the animal type, optionally specifies the breed or size category, enters the real age — and immediately sees the result in human years with a brief explanation of what this age stage means for health and care.

I handle the entire process: calculation logic, interface, and integration into your existing website design. I create the widget not as a "stuck-on" third-party plugin, but as an organic part of the site — selecting fonts, colors, and spacing to match your current theme. It works correctly on phones, loads quickly, and doesn't pull in heavy external libraries.

This type of tool is often bookmarked and sent to friends — it helps both visitor engagement and your website's search visibility.

What's included in the work:
— separate formulas for dogs, cats, and other common pets with adjustments for breed size
— neat adaptive interface matching your website design
— explanation of the result, not just a bare number
— additionally: advice on the pet's life stage, result card for saving, multiple language versions
— clear code with comments so your team can adjust texts or add an animal type themselves
