Although I agree with you, manga =/= anime. Of course, that would most likely be the case if the anime actually followed the storyline presented for them in the games correctly. :/
Also, what the hell is wrong with your eyes? They look NOTHING alike. o_O Please, tell us how they look alike before randomly saying they do just to connect them as being something more. (: One more thing, Sakaki's Persian was NEVER shown to dislike being in a Monster Ball. The only reason he keeps it out like that is to parody your typical, cliché villain in movies where the main villain owns a cat and constantly keeps it on his lap and pets it. You don't see Satoshi constantly giving Pikachu a back-rub, do you?!
