This is not a new issue with LLL - it seems that with every satisfied customer they have, there is also a story like Mike's.
The good news is that replacing or refunding sick animals is something they have a lot of experience in. The bad news is that after 10 days they probably won't do it willingly.
There is enough history on the BOI regarding their spotty health issues that members of this forum can determine whether this is part if a pattern or an anomaly.
Once you figure that out, send LLL a message and let them know that members of this forum will not tolerate them not making this right for IUD Mike.
