Thanks Lorna for the info. What I got stuck on was the word "compensated" don't know why, just never hear it with IR before.

Anyway I found the IR calculator
http://www.freil.com/%7Emlf/IR/ir.html and passed all the information on to my vet.

Thanks for catching this! Alita and I appreciate it very much! I will keep her on an IR diet. I feel blessed this was caught early before she foundered!

Now on to getting her COPD under control.
