so, how would you have felt if Mrs Rice decided not to give Sparkle back to you one day? What if, in her mind, the cat preferred her company and obviously you were abusing the kitty since she kept escaping your apartment to begin with?

Things are not always as they seem. Perhaps Crayon's kitty is just as happy and content in his own apartment as he seems to be in Crayon's. So what if he's shy? The only thing the other people are guilty of is letting the cat get out.
