Sue, I'm sorry I'm getting in on this so late.
I just can't belive that Smiley has Addison's (and that the vet bill was $1574.80 ).
Rachel's right, this must be your parents mission. I'm glad they are able to afford to give her the monthy shot.
Please tell them that they and Smiley are in my thoughts and prayers.
Please keep us updated when you can.
Anna
