Basil is safe for cats in small amounts. Plain fresh or dried basil is non-toxic and even listed as safe by animal poison experts, so a curious nibble of a leaf is no cause for alarm. It offers a cat little nutrition, though, and large amounts of any greenery can loosen the stool.

Why this answer
Basil is a non-toxic culinary herb, confirmed safe for cats by poison-control references, so unlike many aromatic herbs it carries no oil-based toxicity concern in ordinary amounts. It provides trace vitamins and antioxidants but nothing a complete cat diet lacks, and because a cat's gut is not built for lots of plant fiber, only small nibbles make sense.
Watch for
Mild loose stool if a cat eats a lot of leaves
Occasional vomiting of undigested greenery
How much is okay
A small torn piece of plain basil leaf as an occasional nibble, not a regular addition to meals.
Serve it safely
Rinse fresh basil to remove any pesticide residue before offering.
Tear a small plain leaf; skip pesto and oily, garlicky preparations.
Grow it where a cat cannot strip the whole plant.

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.
