Alright Blooper, I'll start with yours since it's the easiest and I'm too tired right now for extensive reading :P

First: I'm not comfortable approving an ability that lets a character move faster than the max for their stated tier, even temporarily. Until or unless LeeRoy decides an ability like that would be okay, I'm going to have to say no to the 400 mph blurring in tier 3.

Second: What exactly does extreme stealth do?

Third: Could you elaborate on the properties of the bo staff?

Fourth: The only physical ability of his that you mention is his speed. What about his strength? Durability? Agility and coordination? If his speed comes from the strength of his legs, can he also jump really high? What about his senses (aside from night vision)? Are they heightened like other felines?

Fifth (and this is just more of an observation): If his fur is only half an inch long, he wouldn't have anywhere to hide a medical kit. He could certainly still carry one, but his fur wouldn't be long enough to conceal it.
