Why this answer
Certain molds that grow on food, dairy, and nuts produce tremorgenic mycotoxins — toxins that overexcite the nervous system and cause muscle tremors and seizures. Spoiled food may also harbor bacteria and their toxins. A cat scavenging from the trash or compost can meet a concentrated, dangerous dose.
Watch for
Fine muscle tremors or twitching
Restlessness or agitation
Vomiting or diarrhea
Incoordination or staggering
Seizures in serious cases
How much is okay
None — never let a cat eat moldy or spoiled food; discard it where the cat cannot scavenge.
Keep it away
Take out the trash and keep bins closed so a cat cannot raid spoiled food.
Do not offer a cat leftovers that are past their prime or show mold.
Keep compost in a sealed container, away from where the cat roams.

Answer card
No food checked yet.
Type what your cat is eyeing — or already stole — and the answer lands right here, without leaving the page.
Remove access. Take the food away and move your cat to another room.
Note the facts. What was it, roughly how much is missing, and when? Keep the packaging.
Call before symptoms. For chocolate, onion, garlic, grapes, raisins, alcohol, or anything sugar-free (xylitol), call a hotline or your veterinarian now — early treatment is easier and cheaper.
Never do this
Do not induce vomiting, feed milk, salt, or oil, or wait overnight to "see how it goes". Signs of chocolate or Allium poisoning can take hours to days to appear.
Go to an emergency vet immediately if
Your cat is collapsing, twitching or seizing, struggling to breathe, drooling heavily, vomiting repeatedly, or wobbly on their feet.
