It is not recommended for cats to eat sultanas due to its harmful compounds.
Sultanas are dried fruits. They usually come from green seedless grapes, which turn gold or yellow after being coated then dried in an oil-based solution. However, sultanas can also be dark brown in colour when made without the drying solution. Just like grapes, it is not recommended for cats to consume sultanas. This is due to an unknown medical compound in the dried fruit, which can cause acute kidney failure in cats.
What to do if your cat accidentally eats sultanas: Get in touch with your veterinarian as soon as possible. Keep a close eye on your pet cat and observe her for any changes in her mood and eating, drinking, or toilet habits. Vomiting and hyperactivity are early signs of food poisoning. Additionally, she may also exhibit these symptoms: diarrhea, abdominal pain, and anorexia.
In summary: High in natural sugar and carbohydrates, sultanas should never be fed to your cat as a treat. Studies have proven that these dried fruits are highly toxic and may cause irreparable damage to your cat. Instead of giving her sultanas, present her with other fruits such as apples, blueberries, mangoes, pineapples, strawberries, and watermelons. Consult with your veterinarian to find out how much and how often you can serve these fruits, making sure they do not go beyond 10% of her total daily calorie intake.
