If you are someone who loves and wants to figure out what your cat is trying to communicate, you'll find that you can learn a great deal simply by observing how your cat interacts with you. Through their body language and through their vocalizations, you'll find that cats are always trying to get their point across, whether they are looking for attention or are feeling scared and nervous and need to be left alone.
The first thing that you will notice is that there is a lot to say when it come comes to your cat's voice. If your cat lives with humans and no other cats, you'll find that they can be quite vocal, and that this is something that can increase over time. Everyone knows that a purr is a happy thing, but you'll find that other vocalizations mean different things as well. A high, kittenish mew can mean that your cat needs some attention and petting, while a hiss or a spit means that it's time to give your cat its space. Sometimes, you'll find that cats can imitate human tones or even sounds that you hear around the house.
You cat expresses a lot of feelings with their tail. Take a look at their tail. If they are hunting it will twitch from time to time, as well as their back. The more upset your cat gets the more their tail thrashes around. When it poofs up that means they're scared of something.
Have you ever noticed that your cat is pushing on you with his forepaws? A cat who is doing this is often feeling content or sleepy and they might do it on their favorite people or even on their bed or their favorite toy. This is a motion that is strongly associated with milk and comfort for your cat. Sometimes cats will knead to show that they are uncomfortable, but for the most part, they are doing this because they are feeling good. Another sign that your cat is comfortable is that they might sprawl over on their backs or roll around.
Another good sign to watch for is heading butting. Head butting you on your head or face is a form of hello. They would do this to another cat in their pack if there was one. Rubbing their lips on you or anything else means it's a safe zone, or a marking of their territory. If you are approaching them and they fall to their side that means they have a great sense of trust in you. This could turn into a sign of affection by them rolling around on their backs.
Take a little time and figure out your cat. This will come in handy when your training them, or trying to stop excessive meowing. The don't meow for no reason at all. They are trying to tell you something is NOT ok. Plus, it will connect you and further deepen your relationship with your cat.
