Zell had been sleeping peacefully. But he always slept without an issue in his animal form. Zell had no doubt it was because he was a Katagaria and his body and soul liked resting in his natural state. It just caused a lot of problems when he needed to get up like for the bathroom or the alarm suddenly going off in his house.
The cheetah was up in a blink of an eye and out of his room even faster. He easily followed the new scent to the house and before Zell could fully realize what he was doing he was tackling Seifer to the ground and pinning him there.
