How we source and review our data

Pet toxicity is a YMYL (Your Money or Your Life) subject in the truest sense - incorrect information can cost a pet its life. This page explains our editorial standards and sources.

Our commitment

TreatorToxic is an educational lookup tool. Every verdict on this site represents a cross-reference of at least two authoritative sources, with preference for peer-reviewed veterinary toxicology research over single-source reporting.

We will always err on the side of caution. If evidence is conflicting or limited, we display a Caution verdict and state the uncertainty explicitly, rather than providing false reassurance.

Primary data sources

ASPCA Animal Poison Control Center (APCC)

Primary

The world's largest database of veterinary toxicology cases. The ASPCA APCC has operated for over 50 years and processes over 170,000 calls per year. Their Toxic and Non-Toxic Plants database and annual Top 10 Toxins reports are primary references for plant data.

Pet Poison Helpline

Primary

Commercial veterinary toxicology service operated by SafetyCall International. Cross-references with ASPCA data where the two services have overlapping case databases.

Journal of the American Veterinary Medical Association (JAVMA)

Peer-reviewed

Peer-reviewed veterinary research. Primary source for mechanistic toxicology data (how toxins work, dose-response relationships) where ASPCA provides clinical outcome data. Referenced for grapes, xylitol, lily, and acetaminophen feline toxicosis specifically.

Merck Veterinary Manual

Reference

The standard veterinary reference. Used for dose-response information, symptom progression timelines, and treatment protocols.

VCA Animal Hospitals - Toxicology Articles

Clinical

VCA Animal Hospitals are one of the largest veterinary networks in North America. Their educational articles are written and reviewed by board-certified veterinarians.

WSAVA (World Small Animal Veterinary Association)

International

International standards body for small animal veterinary practice. Referenced for global toxicology standards and UK/international data.

How we assign verdict levels

SAFE:The substance is not known to cause harm to the specified species in typical quantities. We still note dose-dependence where relevant and when to remove seeds, pits, or skins.

CAUTION:The substance may cause problems at higher doses, for sensitive individuals, or when combined with other factors. Contact your vet if a meaningful quantity was ingested or if symptoms appear.

TOXIC:The substance causes recognised harm. Veterinary guidance is required. Call ASPCA Poison Control or your vet if ingestion is suspected.

EMERGENCY:Life-threatening at typical doses, or has a critically short treatment window. Rush to an emergency vet and call ASPCA Poison Control en route. Do not wait for symptoms.

Review cadence and corrections

All verdict data is reviewed on an annual cycle, with urgent out-of-cycle updates when significant new research or ASPCA guidance changes an established verdict. Each verdict card displays a "Last reviewed" date.

Veterinary toxicology is an active research field. Grape toxicity mechanisms (recently associated with tartaric acid) and xylitol research in cats are examples of areas where understanding has evolved in the past decade and continues to develop.

To report a data error or suggest a correction, email data@treatortoxic.com with the item name, the issue, and a source reference. We review all submissions.

Limitations and what this site is not

-This site is an educational lookup tool, not a veterinary consultation service.
-Verdicts are for the two species listed (dog and cat) only. Rabbits, birds, reptiles, and other species have very different toxicology profiles.
-Individual pet sensitivities vary. A verdict of Safe or Caution for a species does not mean every individual will respond the same way.
-This site does not cover every substance. If you search for something not in the database, call ASPCA Poison Control directly.
-UK and international species names differ from US names for some substances. We note common synonyms but may not cover all regional product names.
