🚨 Critical Emergency Warning

DO NOT WAIT FOR SYMPTOMS TO DEVELOP. If your dog or cat has consumed chocolate, cocoa powder, toxic plants, human medications, raisins, or any known chemical toxin—or is exhibiting acute distress, vomiting, tremors, or lethargy—immediately transport your pet to an emergency veterinary clinic or contact an animal poison control hotline:

📞 ASPCA Animal Poison Control: (888) 426-4435 📞 Pet Poison Helpline: (855) 764-7661

1. Informational & Triage Guidance Only

The content, computational scripts, estimators, and reference materials published on CalculusPet (calculuspet.com) are designed exclusively for general educational, academic reference, and preliminary triage orientation.

None of the calculations or textual outputs provided on this site constitute professional veterinary medical advice, physical clinical evaluation, laboratory diagnosis, or formal therapeutic prescription. No Veterinarian-Client-Patient Relationship (VCPR) is formed between CalculusPet, its creators, and any site visitor.

All calculations are processed strictly client-side within your browser. CalculusPet does not collect, log, or transmit any confidential medical data, health records, or pet biological metrics to our servers or third-party advertising partners (such as Google AdSense).

2. Physiological Inherent Variability & Mathematical Limitations

Biological organisms do not adhere strictly to idealized mathematical formulas. Automated calculations must always be interpreted with professional clinical caution due to multiple confounding variables:

A. Theobromine & Chocolate Toxicity: Theobromine concentrations in commercial confectionery fluctuate widely across brands, harvesting seasons, and batch formulations. Dark chocolate cacao content can vary from 50% to over 90%. Moreover, underlying canine conditions—such as pre-existing cardiac arrhythmias, hepatic dysfunction, or age—dramatically accelerate clinical susceptibility to methylxanthine toxicosis.

B. Caloric & Nutritional Calculations (RER / MER): Our Resting Energy Requirement (RER) formula ($70 \times \text{kg}^{0.75}$) follows the World Small Animal Veterinary Association (WSAVA) global nutrition guidelines. However, a pet's actual daily metabolic energy requirement (MER) can deviate by $\pm 20\%$ to $30\%$ based on neuter status, thyroid function, lean muscle mass percentage, environmental temperature, and individual temperament.

C. DNA Epigenetic Canine Age: Our epigenetic age formula ($16 \times \ln(\text{age}) + 31$) is derived from the pioneering research of Wang et al. (Cell Systems, 2020), which mapped conserved DNA methylation changes specifically in Labrador Retrievers. While scientifically validated for canine epigenetic networks, breed life expectancy varies widely between giant and toy breeds.

D. Feline Gestation & Puppy Growth Projections: Estimated due dates (EDD / HPL / ПДР) and puppy weight projections represent statistical medians (e.g., 65-day feline gestation). Natural maternal variation can span between 63 and 67 days without pathological cause.

3. Affirmative Responsibility of the Pet Guardian

As a pet guardian, you hold the legal and ethical responsibility for the healthcare of your animal companion. You should never disregard, delay, or avoid obtaining professional advice from a licensed Doctor of Veterinary Medicine (DVM) due to any output, figure, or status badge displayed on CalculusPet.
