Aww... that's horrible! I'm so sorry for you! ;_;
I've had pets die or put to sleep before, but to have your pet hit by a car, or worse mauled by a dog, you must feel terrible! One thing's for sure, I wouldn't be too angry with your parents. I agree, it was wrong of them to not tell you the truth right out. So, I suppose you should be angry in that respect.... However, I'm sure you can understand how difficult it is to tell someone something like that? Especially when it involved someone they loved so much. They probably hesitated because they were afraid to hurt you.
It was wrong of them, but at least you can sorta see why they would think of doing something like that.
I hope you feel better soon.... It's really awful when something like that happens.
BTW, Carpet, what do you mean by your comment? Fat cats don't show affection or come up to you...? o.O *is confuzzled*
