\u274c Quick Answer: NO \u2014 chocolate is TOXIC to cats.<\/strong>
Cats are even more sensitive to theobromine<\/strong> than dogs. Even a small amount of dark chocolate can be fatal to a cat. If your cat has eaten chocolate, contact your vet immediately<\/strong>.<\/p>\n<\/div>\n

Why Cats Are Even More Vulnerable<\/h2>\n

While both cats and dogs are sensitive to theobromine, cats metabolise it even more slowly<\/strong>. The lethal dose for cats is approximately 200 mg of theobromine per kg of body weight<\/strong> \u2014 and because cats are typically smaller than dogs, it takes far less chocolate to reach dangerous levels.<\/p>\n

For perspective: a typical 4 kg cat could be fatally poisoned<\/strong> by as little as 20g of dark chocolate<\/strong> (roughly 4 squares).<\/p>\n

          Frequently Asked Questions<\/h2>\n

          Can cats eat chocolate?<\/h3>\n

          No, never.<\/strong> Chocolate contains theobromine which is even more toxic to cats than to dogs<\/strong>. Even small amounts can be fatal.<\/p>\n

          Is white chocolate safe for cats?<\/h3>\n

          Theobromine risk is minimal<\/strong>, but white chocolate is still harmful due to high fat and sugar content, which can cause pancreatitis and digestive upset.<\/p>\n

          How much chocolate is toxic to a cat?<\/h3>\n

          Even a tiny amount can be dangerous. For a 4 kg cat, 10g of dark chocolate<\/strong> (2 small squares) can cause serious poisoning. 4g of cocoa powder<\/strong> can be fatal.<\/p>\n

          My cat licked a tiny bit of chocolate \u2014 should I worry?<\/h3>\n

          A tiny lick of milk chocolate is unlikely to cause severe problems, but monitor closely for any symptoms. If you’re unsure, call your vet for guidance.<\/p>\n
