Not toxic, but hard to digest and a choking risk — they can also go rancid and cause stomach upset. Salted or flavoured almonds are worse.
Short answer
One plain almond is unlikely to be toxic, but it's not ideal. Almonds are hard for cats to digest and pose a choking or intestinal blockage risk, especially for a small cat. Watch your cat closely over the next 24 hours for signs like vomiting, diarrhea, lethargy, or loss of appetite. Never offer almonds intentionally, and if you see any worrying symptoms, contact your veterinarian for advice.
