It's common for people to think that feeding their cats less food is the best way to help them lose weight. But, as it turns out, it's not that simple. In fact, the best way to help your cat lose weight is to switch their food to a highprotein, lowcarb wet food. This way, your cat will feel full and satisfied from the quality ingredients in their food, instead of always feeling hungry from eating a smaller amount of carbheavy kibble.
