Hi Crystal - I wanted to PM you, but I see you're not set up for PMs. Anywho, just wanted to show you this book I ordered:
Amazon.com: Small Animal Clinical Nutrition:... .
While most folks wouldn't find this book too thrilling, I know I will - and I thought you'd probably understand my excitement over the book's 1192 pages of animal nutrition!!! LOL. I will also check, once I receive it, if there is any info on cal/phos - and I could always scan it for you if it proves helpful. Woo hoo!
