All calculators, charts, and articles on Petculate are provided for general informational and educational purposes only. They implement published veterinary formulas, but they are not veterinary advice, and they do not create a veterinarian–client–patient relationship.

• Formulas produce population-level estimates. Individual animals vary with breed, genetics, health status, body condition, and environment, sometimes by a lot.
• Always consult a licensed veterinarian before changing your pet's diet, starting a weight-loss plan, feeding a raw diet, or making decisions about a pregnant, nursing, young, senior, or ill animal.
• Never use this site to delay or replace professional veterinary examination. If your pet seems unwell, contact a veterinarian immediately.
• Petculate and its operators accept no liability for decisions made on the basis of these tools. Use of the site constitutes acceptance of this disclaimer.
