When Mordecai was just a kit, he was stolen by foxes. They never had the intention to harm him, not at all. Surprisingly, they raised him as their own. When he was old enough, Mordecai set off on his own with the belief he was a fox himself. It wasn't till' he came across a pond that he looked at his reflection only to find out he's a cat! He's brushed off that nonsense now, but every now and then he runs with the foxes as if he were of their own.
