Mandy, I just wanted to send some hugs your way for you and your furbaby. This sounds like an awful situation and I hope you get some answers soon.
ScottieDog & DiandPat same hugs for you. It is sooooo hard when our babies have problems
Just a side note, there is lots of good discussion in this thread that might be being overlooked at the original thread is quite old and not really that related to your cases. If you started a new thread you might get some additional advice.
Good luck to all
