Cats have ways to show that they love you! If your cat slowblinks at you,headbutts,purr,meows a lot and kneads, then this is your cat's way of showing affection! However, if your cat meows, then it could just mean that they need or want something such as food. If your cat uses a high-pitched meow then this could mean that they are saying hello. Their diet is lots of protein ,but not many carbohydrates.
