My cats are my children. When I get home, I greet them and hug them and tell them i missed them. They push their noses against mine and sometimes they will even try to lick me.
Some people believe that cats do not show as much emotion as dogs or humans. I personally do not believe this. My cats show emotion, every day its just taking the time to understand what they wanted. Of course they show and tell when they are hungry. They are smart enough to act cute to get our attention and follow them to their food bowl. The emotion i enjoy the most is knowing when the are content. The purring and showing their bellies lets me know that i am being a good owner. Its a nice feeling knowing someone counts on you and needs you like an actual child. Having cats really brings joy in my life.
