Jen,
First and foremost, let me tell you how truly sorry I am that things have gone so badly, both in with your animals and your personal issues - last I talked to you, I really thought things were looking up on both fronts.
I think that when bad things happen, sometimes we don't necesarily think as clearly as we should sometimes, and lord knows you've had a lifetime's worth of bad things going on in the last year or so. I really think you need to step back and rethink selling these racks...lord knows there's perhaps people out there who could make themselves see past the possible implications of this virus out of their own greed and buy them, but certainly there is no way of knowing if you can truly deem them safe. Even with everything you have tried, you couldn't eradicate the virus - now it seems that a simple dose of bleach is the answer to making certain it's not carried by the racks? I know I surely wouldn't feel confident in such a decision, and I can't imagine how I would feel if I found out that down the road, the virus had been spread to someone else's collection because of selling the racks to them, and they ended up going through the same heartbreak of watching their animals die. Or, they may see then start to die, then quick-like sell the animals off, spreading it even further. I couldn't take that chance, not only for the sake of everyone else's animals, but for the sake of my own sanity as well.
And I do have to address the issue with the G stripe as well....this person taking him back to be "just a pet for his kid brother" is ludicrous at best. If the animal was a carrier, how is he to know that he couldn't be bringing infection back to his collection any time he goes to his brother's? Or his kid brother comes to his house? I really can't believe anyone with an ounce of common sense would take that chance.
