Why this answer
Crackers are baked refined flour with a surprising amount of added salt, and cats need very little sodium. Regular sharing adds up quickly in a small body, and many popular crackers are seasoned with onion or garlic powder, concentrated allium forms that damage feline red blood cells. The carbohydrate itself offers a cat nothing.
Watch for
Increased thirst and urination after a salty snack
Vomiting or diarrhea
Weakness or pale gums from red-blood-cell damage if the crackers were onion- or garlic-seasoned
How much is okay
None routinely; a nibble of a single plain unsalted cracker at most, and never garlic- or onion-flavored ones.
Serve it safely
Choose only plain, unsalted crackers if you offer any at all.
Avoid flavored, cheese, and seasoned crackers with onion or garlic powder.
Break off only a crumb rather than a whole cracker.

People Foods to Avoid Feeding Your Pets
ASPCA Animal Poison Control Center — Multi-species veterinary toxicology list covering alcohol, chocolate, caffeine, citrus, coconut, grapes and raisins, macadamia nuts, milk and dairy, nuts, onions, garlic and chives, raw meat and eggs, salty snacks, xylitol, and yeast dough.
Allium spp Toxicosis in Animals
Merck Veterinary Manual — Onion, garlic, leek, and chive toxicosis: organosulfur oxidants cause Heinz-body hemolytic anemia; cats are notably more sensitive than dogs; raw, cooked, and powdered forms are all hazardous.
Feeding Your Cat
Cornell Feline Health Center, Cornell University College of Veterinary Medicine — Feline nutrition fundamentals: cats are obligate carnivores; complete balanced cat food should be the diet base; treats should stay a small share of daily calories.
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.
