A small piece of plain tofu is not toxic to cats, and its blandness makes it low-risk, but it is a poor protein for a carnivore. Tofu is soy-based, and plant protein does not supply the taurine and amino acids cats get from meat. Soy can also cause gas, and seasoned or fried tofu adds problems.

Why this answer
Tofu is made from soybeans, and while it is protein-rich for a plant food, that protein is incomplete for an obligate carnivore that needs taurine and specific amino acids only animal tissue provides in the right form. Soy is also a common cause of gas and digestive upset in cats, and marinated, fried, or garlic-and-soy-sauce tofu dishes add salt and toxic seasonings on top.
Watch for
Gas, bloating, or loose stool from the soy
Vomiting after a larger serving
Digestive upset from seasoned or fried preparations
How much is okay
A small cube of plain, unseasoned tofu on rare occasion, as a novelty rather than a protein source or meal.
Serve it safely
Offer only plain, unseasoned, cooked or silken tofu in a small piece.
Avoid fried tofu and dishes with soy sauce, garlic, or onion.
Do not use tofu to replace meat protein in a cat's diet.

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.
