Yeah, I know how you feel Bridge.  I cried when I wrote the chapter and again when I was double checking the proof reading. I was going for honest feeling here. 

I've had cats all my life as well.  We had to put our first one down when I was just about 8.  She had cancer and was suffering.  This was after having one surgery too.  I couldn't go into the room.  It was too hard.  I sat in the car playing with a stuffed animal when they did it.  I hated talking about it for years.  It still bring a tear to my eye almost 20 years later. 

Yeah, Harry is going to feel bad about it for a while.  At least he has people who will make sure to remind him whenever he does feel it was his fault, that it wasn't.
