Growing up we lived in the country for a few years. We had a big yellow tabby tom cat named Tomasina. He was the stud of the area and acted like it...one night he played and played like a little kitten for the longest time with me. Then all of a sudden he remembered who he was...got up shook himself off (and looked a little sheepish as if he just realized what he'd been doing) and walked off...me and my mom just laughed and laughed at him!
