Cats normally attain their moisture from their food and not so much from actually drinking instinctively so eating a purely dry food diet deprives them of this therefore it’s good for all cats to get a balanced diet of both dry and wet food. A premium food (like the kind you get from a Pet Store and not the grocery store), although more expensive does offer better ingredients and is a healthier option. Like the commercials on TV things like gluttons and meat by-products rank high up in the list of ingredients it’s probably not a great product to feed your cats, liken it to feeding them McDonald’s every night.
When entering the world of premium cat food you will come across multiple brands but also food for indoor cats, over weight cats, senior cats, kittens, hairball control, improve skin and coat and on and on. A little research goes a long way to choosing what will work best for your cat, as well if you have to consider other cats in addition to your Bengal.
You don’t need to feed your Bengal a crazy diet, but you do need to be sure you choose a good healthy brand of food and give them a both wet and dry food.
