We're a small operation, but we aim to reply within a few days. The fastest way to get a useful answer:
- Formula or data errors: tell us which calculator, what you entered, what it returned, and — if you have one — a link to the source you believe is correct. Verified corrections ship within days.
- Calculator requests: describe the question you were trying to answer; that matters more to us than the tool name.
- Everything else: partnerships, press, or just saying your dog is a good dog (noted, and correct).
Please don't email pet health emergencies — we're not veterinarians and email is the wrong speed. If your pet may have eaten something toxic, call your vet or the Pet Poison Helpline at 855-764-7661 (US) right away.
