<human>: Hey, so I've never really owned a cat before. I just moved back in with my parents (sad times) and they purchased a cat when I moved out two years ago. 

The cat spends the daytime outside, and at night I open the door and go "kitty!" and it comes running inside. For the first few minutes it eats and wants to be petted. Then it goes NUTS. It will plop down on my lap, laying on it's back, and if you try to touch it it will claw at you in a playful way but it still freaking hurts. It tries to play with my computer wires, scarves, anything string-like. I played with some yarn with the cat but after half an hour I was done and the cat was not. When I try to go to bed the cat is jumping off the top of the piano/other furniture, getting into the boxes (still unpacking from the move) and will generally scratch things and knock things over until I get up and turn on the light. Then it looks at me like "I didn't do it!" As for just trying to kick the cat out, my room is the only room the dog can't get in to so the cat won't leave. Are all cats so playful? I don't have any cats toys or anything, do I need some? How do you tire cats out?

Give me the gist of the text in a nutshell
<bot>: this cat is super playful and way too hyper at night, what do I do to wear it out so I can get some sleep?
