<human>: Can you succinctly summarize the text in 1-3 sentences?

So I was woken up this morning to a guy banging on the door and ringing the bell constantly. When I wandered over to answer the door some random neighbor was standing there. He told me there was a cat on our roof with a bag over its head. I look up onto the roof and low and behold there was a cat squatting at the peak of our roof with a fracking bag on its head.

I rushed back inside and grabbed some shoes. Then went to the garage and grabbed a ladder. I get up on our roof with it being tile and having rained the night before it was slippery as could be. At one point I tried to do a crouching walk up the roof and slipped, and for at least a moment one of those iconic Hollywood person falling off the roof scenes ran through my head. The cat decided it wanted nothing to do with the idiot try his best to fall off a roof so it ran to the far corner at the front of the house. Once there, my neighbor got on the fence near by and was able to grab at the bag and pull it off before the cat ran away like a pussy.
<bot>: Cat was on my roof with a bag on its head. I tried to kill myself by slipping off the roof and got a large bruise on my knee to helped save a cat.
