ASPCA Animal Poison Control — People Foods to Avoid Feeding Your Pets · reviewed 2026-08-07 · confidence: high
Why
Same salt and fat problem in a much smaller animal, plus onion or garlic powder in most flavors.
Signs to watch for if your cat has eaten potato chips and crisps
Drinking and urinating far more than usual
Vomiting and diarrhea
Wobbliness or weakness
Tremors or seizures at high intake
Signs can lag by a day or more, so no symptoms does not mean your cat is clear — call rather than watch.
What to do now
Don't feed it. If your cat has already eaten some, call your vet or poison control with the amount and the timing and follow their advice.
Never induce vomiting and never give any medicine unless a vet tells you to — it can do more damage than the poison. What we will and won't tell you.
Safer alternatives for cats
A small piece of plain cooked chicken or turkey
Plain cooked fish, boneless and unseasoned
A vet-approved commercial cat treat, kept to under a tenth of daily calories
Cat grass grown indoors instead of houseplants
Fresh water — a fountain tempts many cats to drink more
