I was beginning to despair of my two cats ever becoming friends. The new kitten was rowdy and playful and Charley wanted nothing to do with him. Honestly I was afraid she would hurt him, she was so mean. It didn't phase Clyde at all, though. He continued to stalk her, pouncng until she'd kick his butt so thoroughly he'd back off for a bit to lick his wounds and rethink strategy.
Otis never minded about Clyde. Clyde could chew Otis' tail to his heart's content. He chewed Otis' legs like chicken bones, chewed his ears like rags.
Otis let the kitten do as he pleased, only sitting on him now and again to get a break.
Then we noticed a slow change in Charley. She was curious, getting closer and closer and even...playing! with Clyde.
