Sue,

Bandit will stay in my prayers. I agree it is very frustrating
to only get small answers to the questions in your mind about
what exactly is causing Bandit's problem. Hopefully the tests
will reveal more specific details & that boy can be made healthy
again. I hope you get to go with on next visit to with the Vets
and maybe they can answer more questions & offer more
help for Bandit. Hugs & prayers from Liz & Moki.
