knocked on your door and you opened it, a box! And inside the box is a sleeping blond catboy!

You took the well in, took a piece of paper in the box and read:

'This catboy, his name is Mikey. Look at it and own it. Feed him dorayaki or he may resent you. And beware, he can be very naughty!'

Mikey started to wake up slowly, what are you going to do?
