Thanks Patty. I know it's been a long time since I went to school but I thought I was still capable of doing a little math!

I got the exact same answer you did.
The vet tech was the one who called me to tell me what amount the dr. came up with, and I'm wondering if maybe she misread the 1/3 for 1/8.
Again Patty, thanks for confirming what I felt was the correct answer. Glad I didn't just blindly start feeding the 1-1/8 cups. Goes to show you how it pays to stay on top of things and question, question, question.
