I'm sorry but I am going to come across a bit harsh but I can't help it. First of all I think your friend is seriously irresponsible! She should have NEVER left the cat in the dryer in the first place. Would she allow her child to play in the traffic? That little act had the potential to be a disaster which it ultimately became. Part of being a responsible pet owner is to foresee, as much as humanly possible, dangers that our animals might be exposed to. I also think the roommate and her friend are idiots. (Sorry again for the harsh words) I can't imagine anyone not checking to see what the noise was. This story is very upsetting to me and I don't even know the kitty involved but it breaks my heart. I hope your friend and her roommate have learned something.
