I dont think he was being agressive. JUst sounds like the normal post bathh zoomies that do sometimes get out of control
Keely gets them after every bath time. It seems like there way of saying `Thank god its over and Im out of that stupid bath, my momma was trying to drown me!`kinda thing..lol.. And as for the peeing in the house. He probably drank some bath water and he needed to pee reaaly bad. Keely sometimes does that too. And he may have been damp and didnt want to go outside because its cold? I know keely has also done that..lol
