Oh, do I know the feeling of having a chronically ill pet. :( Thankfully, all our current ones are healthy, but that can change. Hopefully not for a long time!

Not superstitious but I will be metaphorically crossing everything I can cross, for it not to be lymphoma. We lost our Leela to lymphoma in '09.

It sounds like at least you have some great support from B. Best of luck to you all!
