<human>: Can you condense the text into a few key points?

My cat dusty, is a indoor outdoor cat. For whatever reason, when you try to pet him while hes relaxing outside he'll run way from you into bushes or something. I tried to pet him and he ran into a little strip of trees that separate the (busy) road from our house. I thought little of it because I assumed he had enough sense to stay away from the cars.

I went away to the skate park for some fun. When I got home some guy came over to cut up a giant tree that had fallen on our lawn. He went to the tree and came back a few minutes later and asked us if we *had* a cat. Fuck. Dusty's leg was ripped off and he bled out behind the tree a few feet from our front door. I guess he got hit by a car. I wish I hadn't tried to pet him, and I don't think I'll tell my family I tried to. He had 4 leisurely years on this earth.
<bot>: Inadvertently chased cat into road where he lost a limb, made some poor guy tell my family that my cat was dead, and everyone in the house helped dig the grave.
