Sunflowers are safe and non-toxic for cats. Cats can nibble on sunflower petals or leaves without serious harm, but too much sunflower consumption might cause mild digestive upset such as vomiting or diarrhea. The seeds themselves aren't toxic, but sunflower seed shells can be a choking hazard or cause internal irritation, so it's best to prevent cats from eating the seed shells. Sunflower oil is also safe for cats in small amounts and might even provide some health benefits. To keep cats safe and comfortable, it's advisable to keep sunflowers out of their reach or discourage excessive nibbling to avoid digestive issues.
