Human Foods and Medications That Are Toxic to Pets
A lot of ordinary household items are more dangerous to pets than people expect, often because pets process them very differently than we do. This isn't an exhaustive list, but it covers the ones that come up most often.
Foods to keep away from pets
- Chocolate — the darker and more concentrated (baking chocolate, cocoa powder), the more dangerous, especially for dogs
- Xylitol — a sugar substitute found in sugar-free gum and some peanut butters; extremely dangerous for dogs even in small amounts
- Grapes and raisins — linked to kidney failure in dogs; the exact mechanism isn't fully understood, so there's no known 'safe' amount
- Onions, garlic, and chives — can damage red blood cells; cats are especially sensitive
- Alcohol and caffeine
- Raw bread dough containing yeast — it can expand in the stomach and produce alcohol as it ferments
Medications that are dangerous — even common ones
- Human pain relievers like ibuprofen and naproxen — toxic to both dogs and cats, with very little margin for error
- Acetaminophen (paracetamol) — particularly dangerous for cats, where even a small amount can be fatal
- Any human medication, supplement, or leftover pet medication not specifically prescribed by a vet for that exact pet
Plants worth knowing about
- Lilies — every part of the plant, including pollen and even water from a vase, can cause fatal kidney failure in cats specifically
- Sago palm
- Certain spring bulbs, like tulips and daffodils
If your pet may have gotten into something
Note what they ate, roughly how much, and when — this matters a lot for how a vet or poison control line can advise you. Call your vet or a pet poison control hotline right away rather than waiting for symptoms to appear; for a lot of these, treatment is most effective in the window before symptoms start.
Don't induce vomiting unless a vet or poison control specifically tells you to — for some substances (and in some animals), that can do more harm than the toxin itself.
Known or suspected ingestion of a toxin, medication, or anything on this list is one of the few situations PetCare always flags as urgent regardless of other symptoms — if you're unsure whether something your pet got into is dangerous, treat it as a reason to call your vet or a poison control line immediately rather than wait for an app's assessment.
