Jeez, I am so sorry to hear that. It's amazing how many blog entries there have been in the past few days about pets suddenly dying. I hope that isn't a harbinger of bad things to come, I've been hoping that 2008 is a whole lot better than last fucking shit year! I hope you're ok and it doesn't get you down too much. R.I.P Edgar.
Sorry about the news, it probably was something he ate alright. I am worried about the ferrets here because they have been spending a lot of time out in the cold.
