Cats can eat a wide variety of fruits. Feeding your cat foods such as cranberries will not harm them.
Overall, it's important to note that cats do not require fruits. While fruits are beneficial to cats, your cat can get all of their essential nutrients from protein.
You can feed your cat foods such as blackberries, cranberries, blueberries and raspberries. Fruits can be choking hazards if the portions are too large, so you should always give portions that are small enough for your cat to chew easily.
