Thanks again to everyone for the thoughts, well wishes, prayers and suggestions....
I did call UT yesterday but I had to leave a message... they will call me back.
Then I called Care Credit, as I have had a card with $2000. on it for about a year now, but I've never had to use it. Well, they closed the account! I went back online and filed for another one, which was approved for $1000. I just got off the phone with them and explained I needed to increase the credit to $4000. to cover my dog's surgery and they refused the increase. Oh yeah, love them credit card companies... makes total sense.
Oh and UT did call back.... they did increase their prices by $500, and due 10% more at the end of the month.
And for the good news... both my vet and UT said that the kidney stones do not need to be addressed, they don't touch them, only bladder stones are a concern... so that's a plus....
Let me see what else I can pull out of my hat.... I'll be back...
