Advertising disclosure

Last updated: October 25, 2026

Petculator is free to use. It is paid for by display advertising (not active yet; we plan to use Google AdSense). Ads are labeled "Advertisement" and are chosen by the ad network, not by us.

• No affiliate links. We don't earn a commission when you buy a product we mention. If that ever changes, the affected links will be marked and this page updated first.
• No sponsored content. No company pays to appear in a calculator, change a default value or be mentioned in an article.
• Ads are not advice. An ad shown next to a calculator is not a recommendation from us or from any veterinarian.
