Pecans are not a suitable cat treat. Like other tree nuts they are rich in fat that upsets a cat's digestion, and like walnuts they can develop molds that produce tremor-causing toxins. Candied and salted pecans pile on sugar and salt. A crumb is unlikely to poison a cat, but pecans offer only downsides.

Can cats eat pecans? 🌰

Why this answer
Pecans are a high-fat tree nut, and that fat is poorly suited to a carnivore's digestion, readily causing gastrointestinal upset. Pecans are also susceptible to the same tremorgenic mold toxins as walnuts when they age or get damp, which can affect the nervous system. Candied, salted, and chocolate-coated versions add sugar, sodium, or outright toxic chocolate.
Watch for
Vomiting or diarrhea from the fat
Tremors or twitching if the pecans were moldy
Restlessness or unsteadiness with mold-toxin exposure
How much is okay
None needed; do not make pecans a treat, and keep candied or moldy ones especially far from your cat.
Serve it safely
Keep pecans, pecan pie, and shells out of a cat's reach.
Discard old or damp pecans that could carry mold.
Avoid candied, salted, and chocolate-covered pecans entirely.

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.
