Proper communication with your cat is possible. Cats are intelligent creatures and although they cannot express themselves with words they can communicate with body language and sounds. These signs of communication are consistent throughout the species.
Did you know when a cat says "meow" it is directed at a human not another cat. This means your fury friend is trying to communicate with you. Perhaps your cat is glad to see you or desires a treat. This is a cats way of getting your attention. This is good as long as it does not get to excessive. This might develop into a habit where there cat starts to "meow" during the night thus disturbing you sleep. That would not be good for health. Pay attention to you cat during the day, especially before you leave the house and after you return from work. Give you cat attention when they need it. You will sleep better and you cat will be much happier.
