How CatCalc Rates Human Foods for Cats
Our method for labeling foods Avoid, Caution, or Small treat: evidence limits, preparation rules, and why we separate dog advice from cat advice.
By CatCalc editorial team · Updated 2026-11-02. General information only—not veterinary advice. We are not veterinarians.
Purpose of the ratings
The Can Cats Eat…? pages answer a practical question: if a cat steals a bite—or an owner is tempted to share—what is the honest risk framing? We are not a poison-control center and we do not provide doses, LD50 figures, or treatment protocols.
Each food page uses a visible label (for example "Do not feed" or "Small treat · cooked"), a short conclusion, a longer "why," food-specific detail when available, and a handling section. Related links point to similar foods so you can compare raw vs cooked eggs, or onions vs garlic, without relying on one generic paragraph.
Three buckets, with nuance
Avoid / do not feed covers foods with well-established hazards for cats (such as chocolate, alcohol, Allium family plants, cooked bones) or foods where evidence is limited in cats but sharing still has no benefit (such as grapes and raisins, where dog kidney injury is established and cat data are sparse). Limited evidence is stated plainly—we do not copy dog toxicity claims onto cats without saying so.
Caution covers foods that may be tolerated in tiny amounts by some cats but bring lactose, salt, fat, incompleteness, or preparation risks (milk, tuna as a staple, raw fish, ham).
Small treat covers plainly prepared items that are generally non-toxic in small portions (cooked unseasoned chicken, plain pumpkin) but still must stay inside the treat calorie budget and never replace a complete cat diet.
Sources we lean on
We prioritize ASPCA people-food hazard guidance, Pet Poison Helpline toxin pages, AAHA/AAFP life-stage definitions for calculator context, Cornell feeding guidance, WSAVA nutrition resources, and clearly marked primary literature when a claim is unusual (for example xylitol in cats). When cat-specific data are thin, we say so. Each page shows a real revision date from our content calendar.
What we refuse to claim
We do not promise that a food "cures" digestion, urinary issues, or behavior. We do not invent case studies, fake vet reviewers, or made-up percentages of cats affected. We do not treat social-media anecdotes as evidence.
How to use the tools together
Check safety on a food page, then portion with the calorie calculator. Life stage from the age calculator is a reminder to match diet type (kitten vs adult vs senior monitoring)—not a medical age certificate. Practical follow-ons: label guide, kitten checklist, senior log.
Corrections welcome
If a page is unclear or a source link moves, email us from the Contact page with the URL and suggested fix. We would rather revise wording than defend a thin or misleading sentence. Cat safety depends on that habit.
Pages in the food section share navigation patterns for consistency, but each item keeps its own conclusion, why-text, handling steps and extra notes so the advice is not a copy-paste verdict with only the food name swapped.
FAQ
Why do some "no" foods say evidence is limited?
Because honesty matters for your cat. If dog data dominate the literature, we warn you not to feed the item and we avoid claiming a proven cat-specific mechanism we cannot support.
Can a "small treat" food become harmful?
Yes—large amounts, seasonings, bones, xylitol-containing brands, or using treats as meals can turn a generally safe food into a problem. Read the preparation section every time.
